A new report from the University of California San Diego’s Scripps Institution of Oceanography has discovered that one fault line in the state could produce a 7.3-magnitude earthquake.
The Newport-Inglewood and Rose Canyon fault systems runs offshore from the San Diego Bay up to land through the Los Angeles basin. Prior to the report, the two systems were considered to be separate, but a recent study by the Institute have proven them to be one continuous system.
If the offshore segments of the system rupture, a 7.3-magnitude quake could occur. A ruptures onshore could produce even stronger quakes.
The Newport-Inglewood Rose Canyon fault system was responsible for a 6.4-magnitude quake in Long Beach that killed 115 in 1933.
