As a volcano becomes active‚ it gives off numerous warning signs that are picked up by volcanologists; hundreds of small earthquakes are caused as magma rises through cracks in the earth’s crust‚ temperatures rise as activity increases and the volcano will start to release gases. The techniques available for predicting and monitoring volcanic activity are becoming increasingly accurate‚ and many volcanoes are constantly being monitored‚ such as Mount Etna. Anyone sharing a region with a volcano should

also known as Mount Calayo (/kəˈlɑːjoʊ/‚ literally "Fire Mountain") is an active volcano on the island of Mindanao in the Philippines. It is 4.5 kilometres south of the city of Valencia‚ province of Bukidnon‚ and 81 km southeast of Cagayan de Oro City BACKGROUND The low cone is grass-covered and andesitic-to-dacitic in composition.

with flow with high velocities. The pyroclastic flow that was seen at the eruption of Mount St Helens‚ USA in 1980 was a result of dense gas and ash combinations. It travelled a total of 25km north of the volcano and had a top temperature of 700’c. The flow was slowed down by ridges around the volcano but it contributed to a $450 million in damages to forestry.

“The Eruption of Mount St. Helens” On May 18th‚ 1980‚ in Washington State‚ the volcano‚ Mount St. Helens erupted. This eruption caused widespread terror throughout the towns surrounding the mountain. The magma from the volcano burned up the forest and killed most of the animals in the area. It affected the wildlife greatly because‚ after the eruption‚ the ecosystem was burned and smoldered thus killing thousands of animals in the region. This eruption was the deadliest of all the volcanic activity

The volcanic peak in this area is called Chances Peak‚ which had been dormantdormant: A volcano is classed as dormant when it is temporarily inactive but not fully extinct. for over 300 years. Then in 1995‚ the volcano began to give off warning signs of an eruption (small earthquakes and eruptions of dust and ash). Once Chances Peak had woken up it then remained active for a period of five years. The

learn about for scientists. A fumarole is a vent in the ground that has heated up groundwater to such a point that it is only steam when it reaches the surface. Most of the time fumaroles form around areas of high volcanic activity‚ or by a dormant volcano. All fumaroles have a long‚ irregular shaped tube that is usually at least a few miles deep and filled with groundwater at the bottom. Pressure built up from tectonic movement can instantly heat up the groundwater and then shoot it up constantly.

wasn’t a name for volcano? Well thanks to the huge eruption in Pompeii a name was created‚Οὐεσούιος. This is because no one in their area was experiencing volcanic eruptions. Therefore‚ when the Volcano called Mt. Vesuvius was showing signs of eruption‚ the people didn’t know because no one was alive to see or be around for the last eruption of Mt. Vesuvius. Pompeii’s volcano Mt. Vesuvius showed many signs of eruption‚ but no one knew it was going to erupt. But the volcano was showing signs

preparation. Common volcanic hazards include: Pyroclastic flows‚ Ash clouds and mudslides. Pyroclastic flows are high-density mixtures of hot‚ dry rock fragments and hot gases that move away from the vent of the volcano at high speeds. They can reaches speeds moving away from a volcano of up to 450 mph and the gas can reach temperatures of about 1‚000 °C. They will catch fleeing victims and kill them instantly thus making them a devastating hazard. Volcanic ash is formed during explosive volcanic
