The slow quakethe longest ever recordedended in disaster in 1861. The central section of the San Andreas Fault usually moves by quietly creeping, but new research suggests it's hosted some serious earthquakes in history. But then the rate jumped suddenly, with the land sinking up to 10 millimeters a year until the 1861 temblor ripped through the region. Now, scientists working on such systems have discovered that the bigger the tremor, the longer it takes to issue an alertgiving people little time to prepare for the big one, but lots of time to brace for a ho-hum event. By Scientists just confirmed a 30-foot void first detected inside the monument years ago. 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. SPORTIVOHo letto e compreso l'informativa sulla protezione dei dati personali. Mexico and Japan adopted earthquake early-warning systems years ago, but they are still imperfect (both have issued false alarms). The quakes can't be felt, but they may be linked to the regular magnitude-6 temblors on the fault. However, alerts are not earthquake predictions, rather they indicate that an earthquake has begun, and shaking is imminent. 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. Official websites use .gov a TIME subscriber. May/June 2022. In the next 30 years, California has a 99.7% chance of a magnitude 6.7 or larger earthquake and the Pacific Northwest has a 10% chance of a magnitude 8 to 9 megathrust earthquake on the Cascadia subduction zone.
