Earthquake alerts are rapidly becoming available to more people around the globe thanks to partnerships among scientists, policy makers and industry. More powerful earthquakes take a longer time to develop, so alerts for the most severe shaking would only go out at the last minute; people at most distances from the epicenter would receive no warning at all before the S wave hit, the researchers write this week in Science Advances. Earthquakes along strike-slip faults can cause tsunamis in certain contexts, a new model shows and such faults exist right off parts of California. "A lot of people have suggested that these bigger, longer slow-slip events are possible," says Laura Wallace, a geophysicist at the University of Texas at Austin and GNS Science in New Zealand, who was not part of the study team.

Authorities Still, the subtle shifts of the subsurface potentially load strain on adjacent zones along a fault, which could increase the risk of a bigger temblor nearby. Their languid energy release means they cause subtle shifts at the surface, so they weren't discovered until GPS technology had improved enough to chart such minuscule changes. Earthquake Alert!
