While it was once believed that the Newport-Inglewood and Rose Canyon fault lines were separate and ran their own course, a new study has confirmed they’re actually connected – and capable of triggering a 7.4 earthquake.
We’ll talk about it in this issue.
THE STUDY AT A GLANCE
Researchers with the Scripps Institution of Oceanography at the University of California San Diego and the Nevada Seismological Laboratory teamed to conduct the study.
Together, they looked at both fault systems and found that the two form an unbroken fault running underwater and stretching from San Diego Bay to Seal Beach in Orange County and on-land to the Los Angeles basin.
PREVIOUS ACTIVITY FOR FAULT SYSTEM RUNNING JUST OFF-SHORE
While most of the fault system is off-shore, it’s never more than 4 miles out.
Relying upon data from past and current seismic surveys, researchers were able to determine that the most recent significant rupture of the fault system happened in 1933 and was centered in Long Beach. It was a 6.4 quake that killed 115 people.
The on-shore segment of the fault system has experienced about 3 or 5 ruptures in the past 11,000 years.
THREAT POSED TODAY
The densely populated regions of Southern California and Tijuana, Mexico are the areas at most risk for serious damage from a quaked triggered along the fault system. Even a moderate quake would have a major impact on the region.
EARTHQUAKE INSURANCE IN CALIFORNIA
As you know, California law dictates that homeowners insurance providers offer earthquake coverage to policyholders. It’s up to you whether or not you want to purchase it.
