- Updated January 01, 2017. The eruption of the volcano at Krakatoa in the western Pacific Ocean in August 1883 was a major disaster by any measure. The entire island of Krakatoa was simply blown apart, and the resulting tsunami killed tens of thousands of people on other islands in the vicinity.

Krakatoa One of the most powerful volcanic explosions in the history of the world occured at Krakatoa in the last century. Krakatoa was formerly a volcanic island located between Java and Sumatra. It was located near a region where the Indo-Australian plate subducts under the Eurasian plate.

List of new islands Another noted new island is Anak Krakatau (the so-called child of Krakatoa, which formed in the flooded caldera of that notorious volcano in Indonesia), which emerged only in 1930. Ample rainforests have grown there, but they are often destroyed by frequent eruptions.

- • Named for the colossal Krakatoan eruption of 1883. • The pyroclastic flows were associated with the collapse of the summit of the volcano and subsequent collapse of the volcanic structure • Collapse was due to the eruption of the pyroclastic material which was so rapid it left part of the magma chamber vacant

Types of volcano Shield volcanoes. Shield volcanoes erupt thin, 'runny', lava that forms a gently sloping structure. Where a volcano produces low viscosity, runny, lava it spreads far from the source forming a volcano with gentle slopes. This type is called a shield volcano.Mauna Kea and Mauna Loa are shield volcanoes. They are the world's largest active volcanoes, rising nearly 9 km above the sea floor around the island of Hawaii.hen magma erupts at the surface it can form different types of volcanoes depending on the viscosity, or stickiness, of the magma, the amount of gas in the magma, and the way in which the magma reached the surface. Different types of volcanoes include stratovolcanoes, shield, fissure vents, spatter cones and calderas.

Hawaiian Volcanoes Are Giant Shield Volcanoes Kilauea volcano Kilauea is one of the most active volcanoes on our planet. The volcano began the longest rift-zone eruption in historic times on January 3, 1983. Lava fountains formed in the rift zone about ten miles below the summit caldera.Powerful eruptions threw molten rock high in the air building a cinder cone.he Big Island of Hawaii was created by five volcanoes: Mauna Kea, Mauna Loa, Kilauea, Kohala Volcano and Hualalai Volcano.The tallest volcanoes in the Pacfic Ocean are Mauna Kea and Mauna Loa. Mauna Kea is the tallest volcano in the Hawaiian chain. It is 4,205 meters (13,796 feet) above sea level.

Types of volcanic eruptions Mauna Loa erupted from NE rift zone vents high on the volcano in the early AM of 6 July 1975; lava flowed toward Mauna Kea. (image from USGS HVO website) Mauna Loa, or Long Mountain in Hawaiian, is located on the island of Hawaii. It is pictured above rising 13,680 ft. (4,170 m) above sea level (this photo was taken from over Loihi seamount, some 30 km or so to the south). Since 1832, Mauna Loa has erupted 39 times; its last eruption was in 1984.

- Shield volcanoes are formed when a large amount of free-flowing lava spills from a vent and spreads widely. The lava gradually builds up a low, broad dome shaped mountain. The famous Mauna Loa in Hawaii is a shield volcano.Thousands of separate, over lapping lava flows, each less then 50 ft thick, formed Mauna Loa.This picture demonstrates the shield volcano.he lava gradually builds up a low, broad dome shaped mountain.

Krakatoa erupts Krakatoa erupts. The volcanic island of Krakatoa near Indonesia erupts on this day in 1883, killing thousands in one of the worst geologic disasters of modern times. The beginning of the amazing events at Krakatoa in 1883 date to May 20 when there were initial rumblings and venting from the volcano, which had been dormant for about 200 years.

Krakatoa Facts Overview. 1  Krakatoa is one of many volcanoes located along an area around the Pacific basin where two huge tectonic plates meet. 2  Krakatoa has erupted repeatedly throughout history, but its place in the record books is due to the series of massive explosions which took place on 26th and 27th August 1883.rakatoa Facts. Krakatoa, arguably the most famous volcano of all time, whose eruption generated the loudest sound ever recorded and went on to inspire one of the most famous paintings of all time, as well as a Hollywood film.

The Biggest Blast from the Past (Exploding Volcano Photo Blog) Anak Krakatau has grown at an average rate of five inches (13 cm) per week since the 1950s. This equates to an average growth of 6.8 meters per year. The island is still active, with its most recent eruptive episode having begun in 1994. Quiet periods of a few days have alternated with almost continuous Strombolian eruptions since then.

Krakatoa The shock waves from the explosion were recorded on barographs worldwide for days afterward. In 1927, a new island, Anak Krakatau , or Child of Krakatoa, emerged from the caldera formed in 1883 and is the current location of eruptive activity. Historical significance The most notable eruptions of Krakatoa culminated in a series of massive explosions over August 26–27, 1883, which w Express yourself.

Volcano Stratovolcanoes or composite volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that gives rise to the name. Stratovolcanoes are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions.trato/composite volcanoes are made of cinders, ash, and lava. Cinders and ash pile on top of each other, lava flows on top of the ash, where it cools and hardens, and then the process repeats. Classic examples include Mt. Fuji in Japan, Mayon Volcano in the Philippines, and Mount Vesuvius and Stromboli in Italy.

Mauna Kea Mauna Kea is considered to be a dormant shield volcano in what is commonly known as the post-shield stage. Submarine eruptions began to build Mauna kea from the sea floor around ~0.8 million years ago. The basaltic shield stage of volcanism began by at least 0.3 million years ago.

It has erupted from three main areas: its summit and two rift zones. Most of Kilauea's eruptions are relatively gentle lava flows.ype: Shield volcano with a cinder cone.

- Some say that Diamond Head isn't a volcano. It is rather like a vent of the Ko'olau Range that was formed. After the eruption that formed Diamond Head, the Ko'olau Range became extinct.Punchbowl Crater and Koko Head is also considered as an extinct volcanic vent because it was formed around the time of the Honolulu Volcanic Series. None of these volcanic vents were formed by the Mount Ka'ala volcano though.fter the eruption that formed Diamond Head, the Ko'olau Range became extinct.
