The figure of 230,000 dead is based on a historical conflation of this earthquake with earthquakes in November 1137 on the Jazira plain and on September 30, 1139 in the Azerbaijani city of Ganja.

You can try to fit an earthquake location on the map just to see how the procedure goes. Note that the earthquake arrives first on station C, so C is a good first guess for the location. Many earthquakes in California occur between 2 and 12 kilometers depth and we will guess a 6 kilometer depth.

The second general type of earthquake wave is called surface wave, because its motion is restricted to near the ground surface. Such waves correspond to ripples of water that travel across a lake. The wave motion is located at the outside surface itself, and as the depth below this surface increases, wave displacement becomes less and less.

HYPO71, a computer program for determining hypocenter, magnitude, and first-motion pattern of local earthquakes, was first released in 1971. It is perhaps the first earthquake location program that achieved worldwide usage, as evidenced by the fact that about 1000 copies of the HYPO71 manual were requested and distributed (Lee, 1990).
