Earthquake faults in Southern California.
Earthquake faults in Southern California.

 

In a recent article in the LA Times, U.S. Geological Survey seismologist Lucy Jones said. “Every earthquake makes another earthquake more likely.” That makes one pause doesn’t it?!?

After a relatively quiet period of seismic activity in the Los Angeles area, the last five months have been marked by five earthquakes larger than 4.0. That hasn’t occurred since 1994, the year of the destructive Northridge earthquake that produced 53 such temblors.

Over the next two decades, there were some years that passed without a single quake 4.0 or greater. Earthquake experts said 2014 is clearly a year of increased seismic activity, but they said it’s hard to know whether the recent string of quakes suggests that a larger one is on the way.

Quakes in the magnitude 4 range are large enough to be felt over wide areas but generally too small to cause much damage. The largest this year was a magnitude 5.1 in La Habra, which caused several million dollars in damage.
