the volcanic features both landward and seaward of the Andesite Line. “The term andesite line predates the geologic understanding of plate tectonics.” In that it was the term first used to describe the unique structure of the gushing destructive volcano boundary. This term used for the first in 1912 by a man known to be Patrick Marshall of New Zealand. The andesite line is located in the Pacific Ocean basin where it stands as the most significant geological region as once again its unique characteristic

Nonexplosive Eruptions * Most common type * Laval flows from them calmly. (can be huge amount) Explosive Eruptions * Rarer than nonexplosive eruptions * Are very destructive as pyroclastic materials are flung into the air. 7. What materials erupt from a volcano?

that produced these explosive eruptions (VEI 3>=3; 2001-2012) is the strato-volcano. The nature of these volcanoes in general. Is that they have deadly pryoclastic flows of hot fragments and toxic gases the explosive nature comes from silica in the magma. The few other types of volcanoes are shield‚ cinder and complex (compound) volcanoes. One type of volcano is‚ Etna this volcano is also entitled a “strato volcano” it produces violent activity including lots of ash‚ lava and gas which causes

historic eruptions have a lot in common. For example‚ both were preceded by tremors and small earthquakes in the days leading up to both of the explosions. Another example is that both are the same type of volcano called a stratovolcano that spew a lot more ash and pumice than other types of volcanos. The final example is that both spewed tons of ash and pumice and in both situations that was why they were considered deadly. Those are examples of the similarities these
