LAB EXERCISE, INTENSITY ANALYSIS OF AN EARTHQUAKE
This photograph shows some of the damage caused by the great 1906 San
Francisco earthquake and resulting fires. The latter were initiated
by an unfortunate combination of broken gas lines and broken electrical
power lines. For more photographs like this one, check out the
excellent site, called The
San Francisco Earthquake, prepared by the United State Geological
Survey. Here's the latest USGS web site on the Great San Francisco
earthquake, complete with animations, on the occasion of the 100
The great 1906 San Francisco earthquake was caused by a sudden movement (displacement) along the San Andreas Fault, which cuts through the State of California from the southern border with Mexico to just north of San Francisco. The San Andreas fault is a transform plate boundary separating the Pacific plate and the North American plate.
The lab exercise is organized in two parts: (1) you will examine the nature of the movement along the San Andreas Fault, and (2) you will do an intensity analysis of the 1906 San Francisco earthquake.
