Earthquake hazard zones define areas subject to three distinct types of geologic ground failures: fault rupture, where the surface of the earth breaks along a fault; liquefaction, in which the soil temporarily turns to quicksand and cannot support structures; and earthquake-induced landslides. A 3.6 magnitude earthquake was recorded Sunday morning in Los Angeles, the U.S. Geological Survey said.

Show quakes near me! Earthquake hazard zones define areas subject to three distinct types of geologic ground failures: Although strong ground shaking is responsible for most earthquake-related damage, these zones identify areas where earthquake hazards other than structural shaking specifically ground failures during an earthquake are more likely. The zones trigger geologic and engineering investigations that can identify and mitigate the ground failure hazard before construction begins, thereby making the structure itself more resilient to potential shaking. This zone is capable of generating a magnitude 9 (or larger), Very large earthquakes occurring close to the coast could cause. A particular area can be "having a lot of earthquakes" for many different reasons, and we usually cannot tell why.
