Explanation:

The San Andreas Fault is a transform - type plate boundary. Transform faults are where two tectonic plates slide past each other horizontally. Earthquakes that occur along transform faults are called transform fault earthquakes. A tsunami is a large ocean wave usually caused by an underwater earthquake, landslide, or volcanic eruption, but the question is specifically about the type of earthquake. A volcanic eruption is a different geological phenomenon from an earthquake, involving the release of magma, ash, etc. from a volcano.
