It’s only the fourth time in the 88 years of modern records that such a swarm has occurred in this part of California — a region that raises concern among seismologists for the chance that it can trigger a significant earthquake on the San Andreas fault. https://www.latimes.com/california/story/2020-08-10/swarm-of-earthquakes-shakes-salton-sea-area-raising-worry-about-the-san-andreas
In general, there’s a 20% chance of a magnitude 7 or larger quake on this part of the San Andreas fault over the next 30 years. https://www.latimes.com/california/story/2020-08-10/swarm-of-earthquakes-shakes-salton-sea-area-raising-worry-about-the-san-andreas
Monday’s swarm “does increase the chance of a big earthquake on the San Andreas somewhat,” said USGS research geophysicist Morgan Page. “So it’s definitely something to watch.” Read more from @ronlin: https://www.latimes.com/california/story/2020-08-10/swarm-of-earthquakes-shakes-salton-sea-area-raising-worry-about-the-san-andreas
