Explosive eruptions are powerful volcanic events characterized by the violent release of gas, ash, and magma. These eruptions occur when pressure builds up in a volcano due to the accumulation of magma and gases. When the pressure exceeds the strength of the rock, it results in a sudden explosion, sending materials high into the atmosphere. During an explosive eruption, materials such as volcanic ash, pyroclastic flows, and lava fragments can be ejected at high speeds. These eruptions can pose significant hazards to nearby communities, affecting air quality and causing destruction. Famous examples of explosive eruptions include the Mount St. Helens eruption in 1980 and the Krakatoa eruption in 1883.
