300
This is anything that comes out of the volcano
What is pyroclastic material
300
In order to determine the epicenter of the earthquake, scientists use this method that involves the arrival times of p and s waves at three different locations.

This occurs when oceanic crust moves under continental crust
What is subduction
500
This volcano is low-lying, wide-spread and has very low viscosity magma
What is shield volcano
500
This earthquake hazard occurs when water gets into the loose layers of dirt under ground
