An earthquake is defined as any seismic activity that is caused by either humans or is natural. This activity then creates seismic waves. Earthquakes can be cause by many things, such as, instable faults, volcanic activity, mud slides, land slides and nuclear testing.

High ranked earthquakes are anything measuring above a 5 and have the potential to severely damage structures. Homes can slide off their foundations, or slide off slopes if built with stilts on a hillside an even suffer cracked slabs and destroyed cripple walls. 

California has over 60% of all earthquake risk cumulatively across the country and approximately 2000 faults. This equates to 102 earthquakes per day and 37,000 annually. 

High-risk regions can be verified on the California Governors Office of Emergency Services. Click here to read more info and determine if your home is in an earthquake hazard area. http://myhazards.calema.ca.gov/
