Where are earthquakes most likely to occur in Southern California?
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.
Why does Southern California have so many earthquakes?
The driving force of earthquakes in California is movement along the San Andreas Fault and the many associated faults within the San Andreas Fault System that form the tectonic boundary between the Pacific and North American tectonic plates.
What is seismic zone D?
Seismic Design Category D -Corresponds to buildings and structures in areas expected to experience severe and destructive ground shaking But NOT located close to a major fault. Sites with poor soils are a good example.

What parts of California will be affected by the big one?
The ‘Big One’ is a hypothetical earthquake of magnitude ~8 or greater that is expected to happen along the SAF. Such a quake will produce devastation to human civilization within about 50-100 miles of the SAF quake zone, especially in urban areas like Palm Springs, Los Angeles and San Francisco.
What are the earthquake fault zones in California?
The Pacific Northwest: The Cascadia Subduction Zone. The biggest earthquakes in the country are not in California.
What is earthquake zone 1?
The country sits on the Pacific ‘Ring of Fire’, an arc of intense seismic activity that stretches through Southeast Asia and across the Pacific basin. The country accounts for about 20 per cent of the world’s earthquakes of magnitude 6 or greater.
What are earthquake zones?
Seismologists often use the term seismic zones to mean areas where the seismicity likely shares a common cause. For the purposes of calculating probabilistic ground motions for seismic hazard assessment, seismic zones imply regions on a map which have a common areal rate of seismicity.
