temblor

It’s been an unusually active year for earthquakes in Los Angeles, as Thursday morning’s magnitude 4.7 Malibu temblor shows.

The 1989 temblor was a magnitude 6.9 and centered in the Santa Cruz Mountains.

This year also marked the 30th anniversary of Los Angeles’ last destructive earthquake: the magnitude 6.7 Northridge temblor.

Over that time period, Jones said, there was an average of eight to 10 independent sequences of earthquakes annually that included at least one temblor of magnitude 4 or greater.

A magnitude 3.2 earthquake struck off the coast of Malibu on Saturday afternoon, the latest temblor this month to rumble along the Southern California coast.
