Hesse's journal reports: ...on the 19th [of November 1681] we again lifted anchor and proceeded first to the north of us to the island of Sleepzie (Sebesi), uninhabited, ... and then still north of the island of Krakatou, which erupted about a year ago and also is uninhabited. The ash was also hot enough to burn down … It had two elevations, of which the taller, called the Peak of Krakatoa, rose 2750 feet above the sea. (In November 1681, a pepper crop was being offered for sale by inhabitants. Krakatoa was quiet until December 1927, when a new eruption began on the seafloor along the same line as the previous cones. The "Child of Krakatoa," which was formed after the infamous 1893 eruption in Indonesia, is one of the most active volacanos in the world. Krakatau Krakatau (Krakatoa), is said to have created the worst volcanic eruptions in history, in 1883. The death toll recorded by the Dutch authorities was 36,417, although some sources put the estimate at more than 120,000. Collapse of the former volcanic edifice, perhaps in 416 AD, had formed a 7-km-wide caldera. It was formed sometime within the past million years, when the two plates collided and the Indo-Australian plate began sliding under the Eurasian plate. There were three volcanic cones on Krakatoa island: Rakata, (820 m or 2,690 ft) to the south; Danan, (450 m or 1,480 ft) near the center; and Perboewatan, (120 m or 390 ft) to the north. The eastern side of the island has been extensively vegetated by trees and shrubs, presumably brought there as seeds washed up by ocean currents or carried in birds' droppings (or brought by natives and scientific investigators). The British heavy metal band Saxon also released a song about the 1883 eruption of Krakatoa, called "Krakatoa", on the 2010 re-release of its 1985 album Innocence Is No Excuse. The caldera is part of a volcanic island group (Krakatoa Archipelago) comprising four islands: two of which, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption. Thus, the former volcanic cones were not blown into the air, as was first believed, but sank out of sight, the top of the volcano collapsing as a large volume of magma was removed from the underlying reservoir. The eruption was also reported by a Bengali sea captain, who wrote of the event later, but had not recorded it at the time in the ship's log. This in­di­cates that the is­land sub­sided into an empty magma cham­berat the end of the erup­tion se­quence, rather than hav­ing been de­stroyed dur­ing t… In February 1681, Johann Wilhelm Vogel, a Dutch mining engineer at Salida, Sumatra (near Padang), on his way to Batavia (now Jakarta) passed through the Sunda Strait. The caldera is part of a volcanic island group (Krakatoa Archipelago) comprising four islands: two of which, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption. According to the official records of the Dutch East Indies colony, 165 villages and towns were destroyed near Krakatoa, and 132 were seriously damaged. An Indonesian martial arts action film, Krakatau (1977), starring Dicky Zulkarnaen and Advent Bangun, also set the story on the mountain. At least 36,417 people died, and many more thousands were injured, mostly from the tsunamis that followed the explosion. From descriptions and drawings made by HMS Discovery, the flora appears to have been representative of a typical Javan tropical climax forest. ... Sunda Strait to Sumatra) got to witness rain of volcanic ash as well as pumice (a very light and porous volcanic rock formed when a gas-rich froth of glassy lava solidifies rapidly) (Geology, 2005).

At this convergent plate boundary, the Indonesian-Australian plate is sub-ducting underneath the Eurasian plate. On the morning of Aug. 26, 1883, the residents of the island of Krakatoa in the Sunda Strait of Indonesia, then-Dutch East Indie, arose like it was any other day. Near the volcano, masses of floating pumice were so thick as to halt ships. Christoph Sator/picture alliance/Getty Images Krakatoa Volcano eruption caused atmospheric pressure disturbances that caused sea level disturbances. The 1883 eruption of Krakatoa (Indonesian: Letusan Krakatau 1883) in the Sunda Strait began on the afternoon of Sunday, 26 August 1883—with origins as early as that May—and peaked on the late morning of Monday, 27 August 1883, when over 70% of the island of Krakatoa and its surrounding archipelago were destroyed as it collapsed into a caldera. The detonations of the eruption were heard up to 5000km radius. Krakatoa was apparently uninhabited, and few people died outright from the eruptions. Krakatoa itself was formed in the aftermath of an earlier eruption that created the nearby islands of Verlaten, or Sertung, and Lang, or Panjang. The Sunda Strait was first mentioned by Arab sailors circa 1100. The island group of Krakatoa (or Krakatau) lies in the Sunda Strait between Java and Sumatra. It was orig­i­nally pro­posed that the is­land had been blown apart by the force of the erup­tion. Anak Krakatau is a basaltic andesite cone that has grown following the famous caldera-forming 1883 eruption of Krakatau. From a biological perspective, the Krakatau problem[30] refers to the question of whether the islands were completely sterilized by the 1883 eruption or whether some indigenous life survived. In 2017, the height of Anak Krakatau was reported as over 400 m (1,300 ft) above sea level;[8] following a collapse in December 2018, the height was reduced to 110 meters (361 ft). The fate of north­ern Kraka­toa has been the sub­ject of some dis­pute among ge­ol­o­gists. There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018. On December 29, 1927, Anak Krakatoa emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa. [25]:9, While seismic activity around the volcano was intense in the years preceding the cataclysmic 1883 eruption, a series of lesser eruptions began on 20 May 1883. There were three explosive volcanoes that made formed the island of Krakatoa in 1883. About two dozen variants have been found, including Crackatouw, Cracatoa, and Krakatao (in an older Portuguese-based spelling). In July 1880, Rogier Verbeek made an official survey of the islands, but was only allowed to spend a few hours there. It is estimated that more than 36,000 people died. Updates? Eventually, a fourth island, named Anak Krakatau (meaning "child of Krakatoa" in Indonesian), broke water in August 1930 and produced lava flows more quickly than the waves could erode them. The remnants of this eruption formed Verlaten and Lang Islands. A great glowing fire, which reached the sky, came out of the last-named mountain; the whole world was greatly shaken and violent thundering, accompanied by heavy rain and storms took place, but not only did not this heavy rain extinguish the eruption of the fire of the mountain Kapi, but augmented the fire; the noise was fearful, at last the mountain Kapi with a tremendous roar burst into pieces and sank into the deepest of the earth. Most of the material was new magma brought up from the depths of the Earth, most of it distended into pumice or completely blown apart to form ash as the gas it contained expanded. Ash was propelled to a height of 80 km (260,000 ft). Krakatau (Krakatoa) is said to have created the worst volcanic eruptions in history in May 1883. Summer temperatures in the northern hemisphere fell by an average of 0.4 °C (0.72 °F) in the year following the eruption.[28]. More than 36,000 people were killed. By the 1880s, the islands were without permanent inhabitants; the nearest settlement was the nearby island of Sebesi (about 12 km or 7.5 mi away) with a population of 3,000. (3) Show the stages in the process in which Krakkatau collapsed and then Hnak Krakatoa formed in the course of volcanic eruptions. Anak Krakatoa was formed by the 1883 eruption. Sometime within the past million years, the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash. The islands have become a major case study of island biogeography and founder populations in an ecosystem being built from the ground up in an environment virtually cleaned.[29]. Krakatoa is a volcano in Indonesia that lies at the convergent boundary between the Eurasian and Indo-Australian tectonic plates. Where is Anak Krakatoa? See Krakatoa documentary and historical materials, This article is about the volcanic island (group). How­ever, most of the ma­te­r­ial de­posited by the vol­cano is clearly mag­matic in ori­gin, and the caldera formed by the erup­tion is not ex­ten­sively filled with de­posits from the 1883 erup­tion. It resumed on June 19 and became paroxysmal by August 26. Krakatoa is a volcano in Indonesia that lies at the convergent boundary between the Eurasian and Indo-Australian tectonic plates. The surrounding region was plunged into darkness for two and a half days because of ash in the air. The boat glided over crystal clear water, over an extensive and highly beautiful submarine garden. Ans: – Eruption in 1883 -> Island collapsed two thirds destroyed -> Underwater -> Volcano created -> 1927. That was the Krakatoa itself. See the fact file below for more information on the Krakatoa or alternatively, you can download our 24-page Krakatoa worksheet pack to utilise within the classroom or home environment. Explosions diminished throughout the day, and by the morning of August 28, the volcano was quiet. ... Further, the University of Guelph report said, "giant dust cloud that formed and spread caused darkness in areas more than a 400km radius around the blast.”Darkness was witnessed from the time of eruption till the 28th of August across the Sunda … After the explosion, only a small islet remained in a basin covered by 900 feet (250 metres) of ocean water; its highest point reached about 2,560 feet (780 metres) above the surface. The island group of Krakatoa (or Krakatau) lies in the Sunda Strait between Java and Sumatra. Handl built a house and planted a garden with "four European families and about 30 coolies". Krakatoa is a stratovolcano (composite volcano).A stratovolcano is usually a wide hill that inclines steeply towards the top.Krakatoa was formed due to small eruptions, where the runny, hot lava escaped through the earth and spread out. Together, the islands are a part of the Indonesian island arc … Anak Krakatau, … The eruption produced a massive explosion 10,000 times more powerful than the … It was formed sometime within the past million years, when the two plates collided and the Indo-Australian plate began sliding under the Eurasian plate. At a convergent boundary, one plate sub-ducts under another. [20] These have been tentatively dated as having occurred in 850, 950, 1050, 1150, 1320, and 1530. There were also the tree-covered islet near Lang (Poolsche Hoed) and several small rocky islets or banks between Krakatoa and Verlaten. The rising smoke column of this island can be seen from miles away; we were with our ship very close to shore and we could see the trees sticking out high on the mountain, and which looked completely burned, but we could not see the fire itself.[21]. Its explosive eruption in 1883 was one of the most catastrophic in history. A new island volcano rose above the waterline a few days later. Magma is rising up all along that boundary, making Indonesia a very active area. Even so, there must have been an eruption around this time. Krakatau is directly above the subduction zone of the Eurasian Plate and the Indo-Australian Plate where the plate boundaries make a sharp change of direction, possibly resulting in an unusually weak crust in the region. The explosions were so violent that they were heard 3,110 km (1,930 mi) away in Perth, Western Australia, and the island of Rodrigues near Mauritius, 4,800 km (3,000 mi) away. We also sell mugs, in case you need something to drink our delicious coffee from, and we offer gift cards in several different denominations. At a convergent boundary, one plate sub-ducts under another. A German, Johann Handl, obtained a permit to mine pumice in October 1916. Corals of every shape and hue were there, some resembling sunflowers and mushrooms, others cabbages from 1 to 36 inches (3 to 91 cm) in diameter, while a third type bore a striking likeness to the rose. [20] His lease of 8.7 square kilometres (3.4 sq mi) (basically the eastern half of the island), was to be for 30 years. formation - Krakatoa A composite volcano, such as Krakatoa, is formed when runny lava escapes through a fissure in the earths crust and spreads out. (The Indonesian name for the volcano is Krakatau.) Last earthquakes nearby. In Klaus Teuber's board game Seafarers of Catan, the "Krakatoa Variant" is a scenario involving an island composed of three volcano tiles.[33]. [32] The island was a prominent part of the plot of '"Crack of Doom," episode six of the Irwin Allen television series The Time Tunnel in 1966. What is the highest mountain range in South America? In the 1953 film Fair Wind to Java, an American sea captain and a pirate leader race one another to recover a fortune in diamonds hidden on Krakatoa, which begins its final eruption as they search the island for the treasure. Ancient Krakatoa formed in 419 AD and still exists today in Indonesia. Krakatoa, Indonesian Krakatau, volcano on Rakata Island in the Sunda Strait between Java and Sumatra, Indonesia. He was able to collect samples from several places, and his investigation later proved important in judging the geological impact of the 1883 eruption. This eruption was believed to have been even more violent than Krakatoa's 1883 eruption, and also the one that created Krakatoa's original caldera, which resulted in the creation of Verlaten Island and Lang Island. The volcano was formed by the subduction of the Indian-Australia Plate under the Eurasian Plate. Of considerable interest to volcanologists, this has been the subject of extensive study since 1960. Krakatoa, which is located in Indonesia, is a caldera, meaning it is a large hollow land formation shaped like a cauldron and formed by previous volcanic events. Frequent strombolian activity. A 2019 view of the lake on the Indonesian volcano Anak Krakatoa, which emerged in 1927 from the caldera formed in 1883, with the volcano Krakatoa in the background, between the islands of Sumatra and Java. Life quickly recolonized the islands, however; Verbeek's visit in October 1884 found grass shoots already growing. Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. It is, however, in a somewhat fragile position, and the vegetated area has been badly damaged by recent eruptions. Krakatoa itself was formed in the aftermath of an earlier eruption that created the nearby islands of Verlaten, or Sertung, and Lang, or Panjang. By the 24th of June ash from the eruption reached 20,000 feet (6 km) during the eruptions. August 11- A serious period of time, where ash was piling rapidly on Krakatoa and small eruptions took place. Since the 1883 eruption, a new island volcano, called Anak Krakatau ("Child of Krakatoa"), has formed in the caldera. Anak Krakatoa (English: "Child of Krakatoa") is an island in a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. ‘1883 explosion heard around the world’ Anak Krakatoa formed over years after the explosive eruption of the Krakatoa volcano in 1883, one of … In February 1780, the crews of HMS Resolution (1771) and HMS Discovery (1774), on the way home after Captain James Cook's death in Hawaiʻi, stopped for a few days on Krakatoa. [22] Neither Vogel nor Hesse mention Krakatoa in any real detail in their other passages, and no other travellers at the time mention an eruption or evidence of one. The plates involved in Krakatau are the Eurasian plate and the Indonesian-Australian plate. At its peak, Krakatoa reached a height of 790 m (2,600 ft.) above sea level. Omissions? It was orig­i­nally pro­posed that the is­land had been blown apart by the force of the erup­tion. Hot springs boiling furiously up, through many fathoms of water, were found on the eastern side of Krakatoa, 150 feet (46 m) from the shore. Later, at least two more cones (Perboewatan and Danan) formed and eventually joined with Rakata, forming the main island of Krakatoa. Written by then-guitarist John Curulewski along with Paul Beaver and Bernie Krause, the song tells the story of Krakatoa's eruption and the subsequent return of life to the island. At some point in prehistory, an earlier caldera-forming eruption had occurred, leaving as remnants Verlaten (or Sertung); Lang (also known as Rakata Kecil, or Panjang); Poolsche Hoed ("Polish Hat");[15] and the base of Rakata. He occupied the south slope of Rakata from 1915 to 1917, when he left due to "violation of the terms of the lease." Perboewatan, was the northern most volcanic cone. It is located in between the Islands of Java and Sumatra. Further eruptions at the volcano since 1927 have built a new islands, called Anak Krakatau (child of Krakatoa). Note: Vogel returned to Amsterdam in 1688 and published the first edition of his journal in 1690. Krakatoa is infamous for its violent Plinian eruption in 1883, that destroyed the previous volcanic edifice and enlarged its caldera. Rakata was the only volcanic cone to partially survive the 1883 eruption. It is his party that is believed to have inadvertently introduced the black rat to the island. Explosive volcanoes - Krakatoa eruption. Krakatoa, or Krakatau (Indonesian: Krakatau), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa Archipelago) comprising four islands: two of which, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the famous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption. In 1809, a penal colony was established at an unspecified location, which was in operation for about a decade. On May 20, 1883, one of the cones again became active; ash-laden clouds reached a height of 6 miles (10 km), and explosions were heard in Batavia (Jakarta), 100 miles (160 km) away, but by the end of May the activity had died down. Ancient Krakatoa formed in 419 AD and still exists today in Indonesia. The renowned volcano Krakatau (frequently misstated as Krakatoa) lies in the Sunda Strait between Java and Sumatra. The volcano released huge plumes of steam and ash lasting until late August.[26]. They make up the axis of the Indonesian island arc system produced by northeastward subduction of the Indo-Australian Plate. A high wall of water is formed that is initially higher than 100 metres driven by the shocked water, basalt and air. Thornton mentions that Krakatoa was known as "The Fire Mountain" during Java's Sailendra dynasty, with records of seven eruptive events between the 9th and 16th centuries. The plates involved in Krakatau are the Eurasian plate and the Indonesian-Australian plate. Vogel spent several months in Batavia, returning to Sumatra in November 1681. Krakatoa itself was formed in the aftermath of an earlier eruption that created the nearby islands of Verlaten, or Sertung, and Lang, or Panjang. The discharge of Krakatoa threw into the air nearly 5 cubic miles (21 cubic km) of rock fragments, and large quantities of ash fell over an area of some 300,000 square miles (800,000 square km). Collapse of the former volcanic edifice, perhaps in 416 AD, had formed a … Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. The fine dust drifted several times around the Earth, causing spectacular red and orange sunsets throughout the following year. August 25- Explosions amplified and the ash cloud rose, allowing the volcano to be in paroxysmal stage. The eruption destroyed two-thirds of the island of Krakatoa. Anak Krakatoa (English: "Child of Krakatoa") is an island in a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. A large part of the 1947 children's novel The Twenty-One Balloons by William Pene du Bois takes place on Krakatoa, where several families have established a wealthy and fanciful colony based on fictional diamond mines on the island. Articles from Britannica Encyclopedias for elementary and high school students. This prediction came true on 29 December 1927, when a submarine lava dome in the area of Perboewatan showed evidence of eruptions (an earlier event in the same area had been reported in June 1927). After the dust settled, the island of Krakatau would begin to develop a new volcano known as Anak Krakatoa, “Child of Krakatoa.” This new volcano is active and has been erupting since its 1927 formation from the caldera volcano formed after the Krakatoa eruptions. Since 1927 Anak Krakatau [Bahasa Indonesia,=child of Krakatau], an island and volcano, c.360 ft (110 m), has gradually risen from the sea in the caldera formed by the 1883 eruption. Before the eruption, the volcano stood 790 m above sea level. In his diary he wrote: ...I saw with amazement that the island of Krakatoa, on my first trip to Sumatra [June 1679] completely green and healthy with trees, lay completely burnt and barren in front of our eyes and that at four locations was throwing up large chunks of fire. In which country are the Southern Alps located? Eruptions in the area since 1927 have built a new island at the same location, named Anak Krakatau (which is Indonesian for "Child of Krakatoa"). Hence the name Anak Krakatoa, which means “Child of Krakatoa. Christoph Sator/picture alliance/Getty Images Krakatoa is a modular explosive device used for explosive ordnance disposal (EOD) or demolitions developed by the British company Alford Technologies. Anak Krakatau is a volcanic island located in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. In early 1928 a rising cone reached sea level, and by 1930 it had become a small island called Anak Krakatau (“Child of Krakatoa”). The Anak Krakatoa volcano in Indonesia - the so-called "Child of Krakatoa" - was formed by one of the most deadly volcanic disasters in modern history. Our editors will review what you’ve submitted and determine whether to revise the article. Collapse of the ancestral Krakatau edifice, perhaps in 416 AD, formed a 7-km-wide caldera.Remnants of this ancestral volcano are preserved in Verlaten and Lang Islands; subsequently Rakata, Danan and Perbuwatan volcanoes were formed, coalescing to create the pre-1883 Krakatau … Let us know if you have suggestions to improve this article (requires login). Inside the actual device is C4, and this is used to form the copper into an explosively … Our coffee comes in standard (ground), espresso, whole bean, and single serve cups. The fate of north­ern Kraka­toa has been the sub­ject of some dis­pute among ge­ol­o­gists. Sometime in the late 17th century, an attempt was made to establish a pepper plantation on Krakatoa, but the islands were generally ignored by the Dutch East India Company. At 1:00 pm of that day the first of a series of increasingly violent explosions occurred, and at 2:00 pm a black cloud of ash rose 17 miles (27 km) above Krakatoa. Last year, unbeknownst to the world, it was close to unleashing something similar. In more recent years, it has been the subject of a 2006 television drama, Krakatoa: Volcano of Destruction and again in 2008 as Krakatoa. One of the deadliest volcanic events to ever occur was the 1883 eruption of Krakatoa. Krakatoa is a volcano in Indonesia. However, the volcano’s collapse triggered a series of tsunamis, or seismic sea waves, recorded as far away as South America and Hawaii. With an estimated Volcanic Explosivity Index (VEI) of 6,[3] the eruption was equivalent to 200 megatons of TNT (840 PJ)—about 13,000 times the nuclear yield of the Little Boy bomb (13 to 16 kt) that devastated Hiroshima, Japan, during World War II, and four times the yield of Tsar Bomba, the most powerful nuclear device ever detonated at 50 Mt. Also called Krakatau, Krakatoa is located along an area in the Pacific known as the Pacific Ring of Fire. Note: The dating of these events is currently unknown. [18] Keys explores what he believes to be the radical and far-ranging global effects of just such a putative 6th-century eruption in his book Catastrophe: An Investigation into the Origins of the Modern World. On the same ship were several other Dutch travellers, including Elias Hesse, a writer. The eruptions were initially of pumice and ash, and that island and the two islands that followed were quickly eroded away by the sea. From Krakatau to Bali (16-days study and photo tour to Java, Indonesia) The device is designed to fire a number of different projectiles, operates both in air and underwater, and can be used in a vertical or horizontal orientation. Handl found un-burned wood below the 1883 ash deposits while digging, and fresh water was found below 5.5 metres (18 ft). Indonesia has over 130 active volcanoes,[14] the most of any nation. [5] The pressure wave from the third and most violent explosion was recorded on barographs around the world. Krakatoa Island (Krakatau in Indonesian) is a part of Indonesia and lies close to the Java Sea. As much as 200 feet (60 metres) of ash and pumice fragments had accumulated on Verlaten and Lang islands and on the remaining southern part of Rakata. Krakatoa has been featured as a subject and a part of the story in various television and film dramas. From 1927 till today, in its place now lies the Child of Krakatoa Island as a new volcano has emerged since the eruption of 1883. Prior to the 1883 eruption, … Krakatoa is a modular explosive device used for explosive ordnance disposal (EOD) or demolitions developed by the British company Alford Technologies.The device is designed to fire a number of different projectiles, operates both in air and underwater, and can be used in … Distant Effects of the Krakatoa Eruption . http://ratemyscience.com/ Publish your projects or ideas FREE at Rate My Science. [7] The hillsides were typical of tropical climate; large flocks of parrots, monkeys in great variety, wild-mango and orange groves—a superb scene of plants and flowers of every description, glowing in vivid tints of purple, red, blue, brown, and green—but not water or provisions.[24]. Over the years, three new cones were formed, merging into a single island. In 2018, as Anak Krakatoa violently erupted, its middle suddenly collapsed, triggering a tsunami that claimed more than 400 lives on the islands of Sumatra and Java. The huge waves created when Krakatau erupted were responsible for most of the 36,000 deaths associated with the eruption. (The Indonesian name for the volcano is Krakatau.) (According to Winchester, Handl arrived in 1917 and stayed there for four years.) Subduction is a geological process by which one edge of a crustal plate is forced sideways and downward into the mantle below another plate. There has been sporadic eruptive activity at the site since the late 20th century, culminating with a large underwater collapse of the volcano which caused a deadly tsunami in December 2018, follo… These types of volcanos are typicaly tall and have steep sides. The volcano has an infamous past and with the present continuation of activity (e.g. They found a freshwater and a hot spring on the island. Tsunami Waves Generated by the Explosion of the Krakatau (Krakatoa) Volcano Undoubtedly, the atmospheric pressure waves from the three gigantic eruptions of Krakatoa on August 26 and 27, 1883, which proceeded the fourth paroxysmal explosion, gave rise to tsunami like waves.
