Do many small earthquakes mean a big one is coming?

Scientists finally know how big earthquakes start: With many smaller ones. Faults likely weaken or change before a large earthquake, new research has found. The vast majority of earthquakes we feel come soon after smaller ones, according to new research that provides unprecedented insights into how seismology works.

Although several natural ‘warning signs’ have been proposed (ranging from frog behaviours to cloud patterns), there remains no known way to robustly determine when or where an earthquake might occur prior to its rupture.

What would happen if the San Andreas fault broke?

If a large earthquake ruptures the San Andreas fault, the death toll could approach 2,000, and the shaking could lead to damage in every city in Southern California — from Palm Springs to San Luis Obispo, seismologist Lucy Jones has said.
