Seismic Hazards -- Maps, Probabilities, and EQ Engineering

A seismic zone could be one of three things:A region on a map in which a common level of seismic design is required. This concept is becoming obsolete.An area of seismicity probably sharing a common cause. Example: "The New Madrid Seismic Zone."A region...
Seismic hazard is the hazard associated with potential earthquakes in a particular area, and a seismic hazard map shows the relative hazards in different areas. The maps are made by considering what we currently know about: 1) past faults and earthquakes...
Building code maps using numbered zones, 0, 1, 2, 3, 4, are practically obsolete. 1969 was the last year such a map was put out by this staff. The 1997 Uniform Building Code (UBC) (published in California) is the only building code that still uses such...
Determining your risk with regard to earthquakes, or more precisely shaking from earthquakes, isn't as simple as finding the nearest fault. the chances of experiencing shaking from an earthquake and/or having property damage is dependent on many...
Published maps will only provide generalized, uninterpreted information about specific areas. Every property consists of a unique combination of geologic and structural factors that must be considered to determine what might happen to a house during an...
You should consider the following factors when deciding whether or not to get earthquake insurance:proximity to active earthquake faultsseismic history of the region (frequency of earthquakes)time since last earthquakebuilding construction (type of...

Unfortunately, this is almost the same question as "Can you predict earthquakes?" A particular area can be "having a lot of earthquakes" for many different reasons, and we usually cannot tell why.Sometimes there are many earthquakes because they are part...
Within the next 30 years the probability is 60% that an earthquake measuring >=6.7 will occur in Southern California.
