why did eyjafjallajokull erupt answers?
165015
The cause of Eyjafjallajökull's explosive eruption seemed to be the meeting of one body of magma, made up mostly of the common volcanic rock basalt, with another type of magma within the volcano, consisting largely of silica-rich trachyandesite.

When a volcano erupts it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but on the long term the ash layer, which contains many useful minerals, will be converted to a very fertile soil. Nearly everywhere volcanoes are located people use the rich soil for farming.

Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts. ... If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

The fires had ignition sources. ... Some fires were by scumbags lighting them and some were by lightning. Then we had a combination of things that were the cause of the high voracity of the fires. We are going through a very bad drought.

Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup). It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it.

Volcanoes are formed by eruptions of lava and ash when magma rises through cracks or weak-spots in the Earth's crust. A build up of pressure in the earth is released, by things such as a plate movement which forces molten rock to exploded into the air causing a volcanic eruption.

Japan earthquake, tsunami fears heighten after oarfish sightings. Whilst scientists believe earthquakes are not necessarily a prelude to volcanic eruptions, the Japanese people believe they sometimes are. And given the massive shake Osaka felt before Mount Fuji blew in 1707, they may have good reason.

A strong explosive eruption at Okmok began abruptly at 1143 on 12 July after about an hour of rapidly escalating earthquake activity. Ash and gas from the initial explosions reached at least 15 km (50,000 ft) a.s.l on 12 July and drifted as a large cloud S and E above the North Pacific.

History of eruptions and current monitoring Eyjafjallajökull last erupted in 1821, and the eruption continued intermittently for around two years. A major eruption then began at a nearby volcano, Katla, in 1823.

Volcanic activity has been a big part of the Earth's history, but only after the Earth's surface cooled to form the crust. Indirectly yes.

This eruption caused the melting of large amounts of ice, leading to flooding in southern Iceland. ... One of the main effects of the eruption and the ash cloud that followed, was the closure European airspace for seven days.
