This version of the ShakeAlert system is produces both point source and line source earthquake solutions, has added ground motion estimation products, and the number of false and missed events has been reduced. In action in California, an alert was sent to some 2.5 million people as a magnitude 4.5 earthquake struck the Los Angeles suburb of El Monte last September, de Groot said. More than 55 earthquakes have struck off the Oregon coast, but the swarm is not likely to trigger any danger to those on land. What if we could clean them out? Earthquakes need to be at least a magnitude 4.5 for the USGS' ShakeAlert system to even consider send out warnings to devices that are seeing at least weak shaking, or Level 3 on the intensity. When an earthquake begins, fast-moving P waves are detected, and emergency information can be disseminated before the arrival of slower-moving surface waves. Current building codes are already designed to accommodate the possibility of a supershear-strength earthquake, said Elizabeth Cochran, a seismologist with the U.S. Geological Survey in Pasadena. An earthquake of approximately magnitude 9 in 1700 in Cascadia could have instead been three or four slightly smaller, but still devastating, quakes.

Slow earthquakes have only been recognized since the late 1990s, when they were initially spotted in the Pacific Northwest of North America and in the Nankai region off the coast of Japan. The sensor network has reached target density in the Los Angeles, San Francisco Bay and Seattle metro regions and version 2.0 of the ShakeAlert production system has been deployed. February 2022. If you do have supershear rupture, you can then expect stronger shaking intensities, which then can translate into larger possibilities for damage.. Violent Supershear Earthquakes Are More Common Than Previously Thought Oct. 31, 2022 About 14% of magnitude 6.7 or greater strike-slip earthquakes since 2000 have been supershear.
