How do earthquakes cause tsunamis?
When tectonic plates collide and one plate slides under each other.
What is the definition of a transform boundary?
When two tectonic plates slide past each other.

How does a transform boundary cause a earthquake?
Two tectonic plates grind agaist each other at the boundary.
How are earthquakes formed?
Most occur at fault zones where tectonic plates collide or slide against each other.
What is the definition of tsunami

What is the definition of mercalli scale?
A twelve-point scale for measuring the intensity of an earthquake, ranging from I-XII (1-12).
