DENDROLOGY

Detailed explanation-1: -Greater Bay Area. The greater San Francisco Bay Area has a high likelihood of future damaging earthquakes as it straddles the San Andreas fault system-the major geologic boundary between the North American and Pacific tectonic plates.

Detailed explanation-2: -Since the formation of the San Andreas Fault system 25-30 million years ago, the juxtaposition of the Pacific and North American plates has formed many faults in California that accommodate lateral motion between the plates.

Detailed explanation-3: -The shake table was installed in Parkfield, California, which is situated right on the San Andreas Fault midway between San Francisco and Los Angeles. It is sometimes referred to as the “earthquake capital of California”, due to the large number of M6. 0–6.5 earthquakes that have occurred over the past 150 years.
