Anak Krakatau, one of the world's most active volcanoes, is in the alert level for the Anak Krakatau volcano amid signs of increased activity, Probable intrusion of magma at depth, which can lead to magmatic eruption.

When magma travels up through a volcano's vent, bubbles of gas also appear. All the gas builds up pressure, which causes the magma to explode out of the volcano. When magma is thin, the gas bubbles can rise and pop easily volcanoes located over thin magma don't have very large explosions. While volcanoes can be destructive, they are also responsible for creating rich agricultural soil, minerals like gold and silver, diamonds, hot The Soufrière Hills volcano is an active, complex stratovolcano with many lava domes forming This period lasted for another 60 weeks, after which there were major dome collapses and two periods of explosive The following is a list of Montserrat settlements destroyed the eruption of the Soufrière Hills volcano.
