GEOLOGY

Detailed explanation-1: -Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.

Detailed explanation-2: -Several hazards may affect the area around the volcano, such as lava flows, pyroclastic flows, lahars, jökulhlaups and landslides or debris avalanches.

Detailed explanation-3: -Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.

Detailed explanation-4: -Put simply, a volcano is an opening in the Earth’s surface. The word “volcano” comes from the Roman name “Vulcan”. Volcanoes are often found at meeting points of “tectonic plates”. Volcanoes can also occur over “mantle plumes”. More items
