- Indicates Newport-Inglewood fault more important than previously thought
- Risk in the next 30 years of ‘big one’ increased from about 4.7% to 7.0%
- However, study says risk of smaller quakes has actually gone down
A huge fault in the Earth’s crust near Los Angeles is leaking helium, researchers have found.
They say the unexpected find sheds new light on the Newport-Inglewood Fault Zone in the Los Angeles Basin.
It reveals the fault is far deeper than previously thought, and a quake would be far more devastating.
It follows a report from the U.S. Geological Survey has warned the risk of ‘the big one’ hitting California has increased dramatically. Continue reading
- Simulation of a magnitude-7 quake on the San Andreas Fault. Seismic waves radiate outward, then deep into L.A.
A seismology study by scientists from Stanford and MIT, published in the journal Science on Friday, finds that if the Big One hits the San Andreas Fault near Palm Springs, some seismic waves will travel near the path of the 10 Freeway into the heart of Los Angeles, where the city and its suburbs will suffer stronger ground motions than previously believed. Downtown L.A. will endure three times the shaking of surrounding areas, scientists now say. Continue reading
