A network of undersea faults off the coast of Southern California could produce huge quakes that could send tsunami waves crashing into Los Angeles, new research suggests.
Earthquakes are the result of plate tectonics, or shifting plates in the crust of Earth, and quakes occur when the frictional stress of gliding plate boundaries builds and causes failure at a fault line. In an earthquake, elastic strain energy is released and waves radiate, shaking the ground. Scientists can predict where major temblors might occur in a general sense, but research does not yet allow forecasts for specific locations or accurate predictions of timing. Major earthquakes, some generating tsunamis, have leveled entire cities and affected whole countries. Relatively minor earthquakes can also be induced, or caused by human activity, including extraction of minerals from Earth and the collapse of large buildings.
The powerful aftershock that struck Nepal today (May 12) could trigger deadly landslides on slopes already weakened by the April 25 earthquake, experts said.
