But there's a lesser known fault running through the heart of the San Diego, and it has the attention of emergency planners. The scenario earthquake ruptures a 65-km-long section of the Rose Canyon fault that lies just offshore of San Diego, California, and Tijuana, Mexico. We know all about the San Andreas Fault. Fault Name Index Rose Canyon Fault Zone. The Rose Canyon fault, an extension of the Los Angeles Newport-Inglewood fault, runs along the coast and beneath downtown San Diego.
The Rose Canyon fault in California generates powerful tremors almost twice as frequently as previously believed, and it could trigger a 7.4 magnitude earthquake. San Diego Earthquake Scenario. In this scenario, the rupture starts near the northern end of the fault and propagates to the south. A scenario study on a 6.9-magnitude earthquake on the Rose Canyon fault zone paints a bleak picture, saying the San Diego region could suffer "devastating consequences." San Diego's Rose Canyon Fault is at a greater risk of triggering powerful earthquakes than experts had first believed. In a recent report, earthquake geologists and engineers say this fault is the biggest earthquake threat to San Diego, capable of earthquakes of magnitude 6.9. Fault Name Index Rose Canyon Fault Zone. Type of Fault: right-lateral strike-slip Length: about 30 km Nearest Communities: San Diego, La Jolla, Linda Vista Most Recent Surface Rupture: Holocene, in part; otherwise, Late Quaternary Slip Rate: 1.1 mm/yr; could be greater if unmeasured parallel segments carry a significant amount of slip OVERVIEW. The Scenario earthquake is a M6.9 crustal strike-slip Rose Canyon Fault rupture with a length of 69km, slip of a maximum of 2m, and an epicenter depth of 7.7km. Type of Fault: right-lateral strike-slip Length: about 30 km Nearest Communities: San Diego, La Jolla, Linda Vista Most Recent Surface Rupture: Holocene, in part; otherwise, Late Quaternary Slip Rate: 1.1 mm/yr; could be greater if unmeasured parallel segments carry a significant amount of slip
San Diego’s Rose Canyon fault produces powerful earthquakes more frequently than once believed, but a major temblor isn’t imminent, according to researchers from San Diego State University. The scenario earthquake ruptures a 65-km-long section of the Rose Canyon fault that lies just offshore of San Diego, California, and Tijuana, Mexico.
In this scenario, the rupture starts near the northern end of the fault and propagates to the south. Scenario for a Magnitude 6.9 Earthquake on the Rose Canyon Fault For Earthquake Risk Reduction in the San Diego Region . Today, it’s believed the Rose Canyon fault ruptures in a big earthquake of something approaching a magnitude 7 about every 700 years — give or take 400 years or so. A geology professor at San Diego State University shows us where you can see signs of the Rose Canyon Fault and how dangerous it could be.
