earthquake prediction bay area 2020

In 2015, UC Berkeley researchers suggested that the Hayward Fault may be connected to the nearby Calaveras Fault, which, if true, would mean the potential for a more powerful quake. It’s quite the stretch compared to its bigger neighbors, with only about an eight percent chance to blow by 2043. The South Bay rang in the new year with an earthquake near Morgan Hill late on New Year’s Day, which the U.S. Geological Survey (USGS) initially measured at a respectable, but not particularly worrisome, 3.9 in magnitude.

The fault zone is part of the larger San Andreas fault system, which also includes many of the other major Bay Area faults on this list. The East Bay has a higher earthquake risk than the San …

Circles are earthquake locations, red indicates an earthquake in the past hour, orange the past 24 hours, and yellow the past 7 days. Tuesday is the second in three days that Milpitas saw two earthquakes in one day: on Sunday, a 3.4-magnitude quake with a depth of 5.3 km hit around 3:54 p.m.. Later, at 10:16 p.m., another 3.4-magnitude quake went off. Although it’s certainly capable of producing a large and disastrous quake, this fault zone hasn’t made waves in a long time; the last big one here was prior to 1775, and possibly as far back as 1200 CE. Where things get weird—and potentially more difficult to predict—is where faults meet.

Whereas the southern part of the Hayward Fault can connect to the Calaveras Fault with frightening regional implications (see below), the northern section is more likely to synch with Rodgers Creek; this simulation of a 7.2 magnitude quake affecting both faults shows major shaking extending as far as San Jose in only 40 seconds. Two minutes after 9 a.m., a third earthquake hit, registering a magnitude of 3.3 at a depth 4.3 km. An earthquake swarm of at least three small temblors ranging from 2.7 to 3.3 in magnitude rattled the shoreline of the Calaveras Reservoir east of Milpitas Tuesday morning -- … “If you have really weak material almost like talcum powder, talc, then you can get the fault moving, creeping along slowly instead of getting stuck and having a larger event,” Cochran said. Although generally more quiet than its immediate neighbors, this fault has caused several quakes of 6.0 or greater around Moraga Hill in the past 200 years. Earthquake scientists estimate that there is a 72% probability of a magnitude 6.7 or greater earthquake in the Bay Area in the near future. To learn more or opt-out, read our Cookie Policy. The maximum magnitude a fault can produce depends on its size, but since, as previously noted, fault zones are technically many faults rather than one, their apparent lengths can be deceptive, with some areas stronger than others. A 2018 USGS model predicted that 7.0 magnitude quake centered under Oakland would cause hundreds of deaths and more than $80 billion in damages—even in a best-case scenario. By the time it gets as far north as Lands End, it reaches over three miles west of SF. The state capital city has experienced the effects of … “It’s just California, it is what it is,” said Norman Arnold, of Milpitas. Skateboarders Bomb One of the City’s Biggest Hills for Black Lives, Once a Sign of Blight, Boarded-Up Windows Provide Canvases for Artistic and Political Expression, Here’s Why the Golden Gate Bridge Was Singing, S.F. The fault lies not in our stars but miles below our feet—which, of course, is a problem for anyone living and working in the seismically unstable Bay Area with its ever-ticking geological clock.

2020-10-26 12:42:40 UTC at 12:42 October 26, 2020 UTC Location: Epicenter at 37.292, -121.666 15.2 km from Seven Trees (9.2 miles) San Francisco Bay Area, California MILPITAS (CBS SF) — An earthquake swarm of at least three small temblors ranging from 2.7 to 3.3 in magnitude rattled the shoreline of the Calaveras Reservoir east of Milpitas Tuesday morning — the second time in three days that multiple earthquakes shook the area. The Maacama is part of the San Andreas system and has been called its “sister fault”—hopefully, that remains an estranged relationship. SF’s first sanctioned tent city provides safe—albeit temporary—shelter during pandemic, SF’s best furniture and home design shops. The Hayward Fault, in general, is weaker than its San Andreas neighbor, topping out at quakes of about 7.5 in magnitude. Reignite your apartment or home with a small refresh or total makeover at these shops specializing in furniture and home decor.
