Since this is not my area of expertise, I searched Google under the key words "earthquake wave" to get these possible sources:

I hope this helps. Thanks for asking.

Thank you for using the Jiskha Homework Help Forum. How interesting that you say it is NOT a Tsunami. Here is something from the Tsunami Website on how this wave is caused:

What is a tsunami?
A tsunami (pronounced tsoo-nah-mee) is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life.

The large wave created by some earthquakes that is not a tsunami is called a seismic wave. Seismic waves are vibrations that travel through the Earth's layers as a result of an earthquake or other seismic activity. They are responsible for causing shaking and vibrations on the Earth's surface. There are different types of seismic waves, including P-waves (primary waves) and S-waves (secondary waves), which travel through the Earth's interior, and surface waves, which travel along or near the Earth's surface. These seismic waves can cause significant damage to structures and infrastructure, depending on their intensity and proximity to populated areas. If you want more information about seismic waves, you can search for "seismic waves" on reputable websites such as Wikipedia or educational institutions' websites.
