Glossary of earthquake terms

 

diagram of block and spring

When the force trying to make the block (m) slip becomes greater than the frictional force causing it to stick, the block will slip.

Stick-slip
Stick slip refers to the fast movement that occurs between two sides of a fault when the two sides of the fault become unstuck. Stick-slip displacement on a fault radiates energy in the form of seismic waves, creating an earthquake.
