The San Andreas Fault is a very active fault line that stretches across the central west coast of North America. The fault and earthquakes are caused by a transform boundaries between the plates. How does a transform boundary cause an earthquake?

The two plates slam into one another; increasing momentum and starting an earthquake.

One plate slides underneath the other, causing it to rise up, creating an earthquake.

The plates slide horizontally past one another, increasing stress; once the stress is strong enough, the plates can cause an earthquake.

The plates slide vertically past one another, rising and falling; the friction from this action causes the earthquake.
