On January 23rd 1973 a new volcano unexpectedly erupted in the Vestmannaeyjar archipelago‚ southwest of Iceland. The new volcano was a fissure 1.25 miles long and only 1100 yards from the center of town‚ also named Vestmannaeyjar. The new volcano was named Heimaey. The town was mostly evacuated over the next few days and the lava slowly flowed towards town and the mouth of the harbor for the next seven months. Vestmannaeyjar is the only good harbour in that part of Iceland‚ and was the base for a

Philippine provinces of Zambales‚ Tarlac‚ and Pampanga. Mount Pinatubo is part of a chain of composite volcanoes along the Luzon arc on the west coast of the island. The arc of volcanoes is due to the subduction of the Manila trench to the west. The volcano experienced major eruptions approximately 500‚ 3000‚ and 5500 years ago. Up to 800 people were killed and 100‚000 became homeless following the Mount Pinatubo eruption‚ which climaxed with nine hours of eruption on June 15‚ 1991. On June 15‚ millions

plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning. There are volcanoes that form away from plate boundaries in areas that are called “hot-spots”. An example of “hot-spot” volcano formation is the Hawaiian Islands. Figure 1: (Kreger‚ 2010) The image above shows that volcanoes are created by hot magma that rises from the Earth’s core and expels through the cracks of the upper mantle and ocean crust. The movement of the Earth’s

What is Volcanic Eruption? A volcano can be simply defined as a rupture or an opening on the crust of a planet like earth. This opening allows hot ash‚ molten rock and gases to blow off from the underground spaces. Volcanoes generally acquire shape of a mountain. Volcanoes are usually found at places where tectonic plates get converged or diverged. But there existence at a particular place depends upon many environmental and geological factors. Volcanoes can also occur at a place because of

Mount St. Helens. Mount St Helens is a volcano in a national park in Washington State‚ USA. It had been thought to be dormant for many years‚ until in 1980‚ when it suddenly burst to life.

Decade Volcano by the United Nations. From about 35‚000 to 15‚000 years ago‚ Etna experienced some highly explosive eruptions‚ generating large pyroclastic flows‚ which left extensive ignimbrite deposits. Ash from these eruptions has been found as far away as Rome‚ 800 km to the north. Eruptions of Mount Etna: 2001‚ 2002–2003‚ 2004–2005‚ 2008-2009 and 2011 I It’s been nearly 350 years since Mt.

Though it is near those borders‚ the volcano is in the Democratic Republic of the Congo. The latitude and longitude of Mt. Nyiragongo is 1.5167° S‚ 29.2500° E. Those are the introductory facts to exploring Mt. Nyiragongo; it is very much more than that though. Mt. Nyiragongo is a stratovolcano‚ a composite-cone volcano. It is on the African plate

A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population ’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area without
