Earthquake

EQ mapAn earthquake is a sudden and sometimes catastrophic movement of a part of the earth’s  surface. Earthquakes result from the dynamic release of elastic strain energy that radiates seismic waves.


Earthquakes typically result from the movement of faults, which are zones of deformation within the Earth's upper crust. The word earthquake is also widely used to indicate the source region itself. The earth's lithosphere is a patch work of plates in slow but constant motion. Earthquakes occur where the stress resulting from the differential motion of these plates exceeds the strength of the crust. The highest stress (and possible weakest zones) are most often found at the boundaries of the tectonic plates and hence these locations are where the majority of earthquakes occur.

Be Prepared:
  • Create a Family Earthquake Plan
  • Know the safe spot in each room, (under sturdy tables, desks, or against inside walls).
  • Know the danger spots, (windows, mirrors, hanging objects, fireplaces and tall furniture).
  • Conduct practice drills. Physically place yourself and your children in safe locations.
  • Learn first aid and CPR (cardiopulmonary resuscitation)
  • Decide where your family will reunite, if separated.
  • Keep a list of emergency phone numbers.
  • Choose an out-of-state friend or relative who family members can call after the quake to report your condition. Carry emergency contact cards with out-of-state contact phone numbers.
  • Develop a portable/auto survival kit for work and travel.
