In Alaska, for example, researchers discovered one event that lasted at least nine years, only realizing they were looking at a slow quake after the creeping surface halted in 2004, Mallick says. The discovery of such a slow-moving earthquake promises to help scientists grasp the surprising variety of ways our restless planet movesand the deadly potential for these silent events to spark much more potent quakes. September 2022. If you do have supershear rupture, you can then expect stronger shaking intensities, which then can translate into larger possibilities for damage.. MyShake provides earthquake early warnings in California, Oregon, and Washington for estimated magnitude. The team initially thought the change was due to a shifting region where two tectonic plates lock together, but they weren't sure of the precise cause. Tomorrow marks 323 years since the last Cascadia Subduction Zone earthquake. published 10 May 21. Before joining The Times, she worked as the senior London correspondent for GlobalPost (now PRI) and as a reporter and assignment editor at the Cambodia Daily in Phnom Penh. 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. A subduction zone is a collision between two of Earth's tectonic plates, where one plate sinks into the mantle underneath the other plate.
