L.A. #Earthquake . . Be Prepared

  • Southern California has about 10,000 earthquakes each year, though most are so small that they are never felt.

  • Of those, 15-20 are greater than magnitude 4.0.

  • Large earthquakes create an aftershock sequence that can produce many additional earthquakes of all magnitudes for many months.

  • Earthquakes can occur in any type of weather - cold, hot, rainy or dry. There is no such thing as “earthquake weather.” so earthquake preparedness should be 24/7.

  • The San Andreas Fault is not a single, continuous fault, but rather a fault zone consisting of many different segments. Its fault system is more than 800 miles long.

  • Most earthquakes occur at depths of less than 50 miles below the Earth’s surface.

  • Only four states Florida, Iowa, North Dakota and Wisconsin have not had earthquakes in the past 30 years.

  • Alaska is the most earthquake-prone state, with a magnitude 7 quake or greater occurring nearly every year.
