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 Quake: 1906 San Francisco Earthquake, prepared by the United State Geological Survey, especially the section on CASUALTIES and DAMAGE, where this photograph came from.  Here's the latest USGS web site on the Great San Francisco earthquake, complete with animations, on the occasion of the 100 year anniversary.

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.

PART 1: The San Andreas Fault. For printing a copy of the ANSWER SHEET.

PART 2: Intensity analysis.  For printing a copy of the ANSWER SHEET.
