Mount Tambora
Mount Tambora (or Tamboro) is an active stratovolcano, also known as a composite volcano, on the island of Sumbawa, Indonesia. Sumbawa is flanked both to the north and south by oceanic crust, and Tambora was formed by the active subduction zone beneath it. This raised Mount Tambora as high as 4,300 m (14,100 ft),[4] making it formerly one of the tallest peaks in the Indonesian archipelago. After a large magma chamber inside the mountain filled over the course of several decades, volcanic activit -
Manuna Loa
Big Island, Hawaii
19.47 N, 155.60 W,
summit elevation 4170 m
shield volcano
Mauna Loa volcano is one of the tallest mountains in the world. When measured from its base on the sea floor, it rises more than 17,000 m (56,000 feet). Mauna Loa volcano is in its longest historical period of inactivity, 25 years. Mauna Loa volcano is spreading because its size is large compared to the thin basal layer -
Krakatoa
Krakatoa, or Krakatau, is a volcanic island situated in the Sunda Strait between the islands of Java and Sumatra in Indonesia. The name is also used for the surrounding island group and the volcanoes as a whole. Krakatoa was dormant until 1883, when it erupted catastrophically. By August 11, three vents were regularly erupting on the volcano. During this time tides were unusually high, and phenonema such as windows suddenly shattering were commonplace. Ships at anchor were sometimes tied -
Mount Pelee`
The residents of St Pierre living in Martinique, a French island in the Caribean Sea, had lived for over 2 centuries in the shade of "their" volcano. By 1902 they even had become familiar with the volcano, as if it was a dragon that was sleeping in peace in their back-yard. The strato volcano, called Mount Pelée, was approximately 1400 metres high, cone-shaped and took up a surface of 100m2 on the north part of Martinique. Two enormous black clouds of volcanic material (nuées ardentes) wer -
Mount St. Helens
Mount St. Helens is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles south of Seattle, Washington, and 50 miles northeast of Portland, Oregon. Shaken by an earthquake measuring 5.1 on the Richter scale, the north face of this tall symmetrical mountain collapsed in a massive rock debris avalanche. In a few moments this slab of rock and ice slammed into Spirit Lake, crossed a ridge 1,300 feet high. -
Nevado del Ruiz
Nevado del Ruiz volcano in central Colombia, 130 km WNW of Bogota, is a broad, glacier covered volcano. A relatively small eruption in 1985 caused a devastating mud flow that killed almost 25,000 people in the town of Armero, marking one of the worst volcanic disasters in history. Sadly, this tragedy could have been easily avoided if clear warnings by volcanologists had been taken seriously. -
Mount Pinatubo
The Pinatubo eruption on 15 June 1991 was the second largest volcanic eruption of the 20th century.
Pinatubo is a complex of lava domes located 100 km NW of Manila city, Luzon Island, Philippines.
Prior to the eruption, Pinatubo was a little known volcano and it had been dormant for 400 years. There were no known historic eruptions. Before the eruption in 1991 Pinatubo was 1745 m high (ca. 250 m more than now), and was only 200 m higher than the nearby peaks. -
Eyjafjallajokull Iceland volcano
The volcano of Eyjafjallajokull, located on Iceland's northern coast, has caused the disruption of air traffic across the European continent and a local flood, following an increase in volcanic activity over the last two days. Seismic activity started around Christmas 2009, and led to an eruption on 20 March 2010. The volcanic activity has been ongoing since then, but only in the last number of days has the activity escalated to the extent that we are seeing now.
