NASA Study Improves Understanding of LA Quake Risks

A new NASA-led analysis of a moderate magnitude 5.1 earthquake that shook Greater Los Angeles in 2014 finds that the earthquake deformed Earth's crust across a broad region encompassing the northern Los Angeles Basin and northern Orange County.

Setting of the La Habra quake. Red dots show the magnitude 5.1 main shock, magnitude 4.1 aftershock and magnitude 5.4 Chino quake in 2008. Relocated aftershocks are green dots. Modeled faults are in brown, with the heavier reddish brown line denoting the bottom of the fault and labeled with italics. Credits: NASA/JPL-Caltech
