What is a normal fault?
200
a giant wave caused by undersea earthquakes.
What is a tsunami?

These are locations on earth away from plate boundaries where volcanic activity occurs.
What is a hot spot?
200
This is a high level area made by many layers of lava from cracks in the ground.
What is a lava plateau?
200
this earthquake wave can travel through both liquids and solids.
What are primary waves?

What is a strike-slip fault?
400
a scale based on numerical strength of seismic waves
What is the Richter scale?
