\n Scientists have warned that last year\u2019s Ridgecrest quakes in Southern California have increased the risk of a major San Andreas Fault earthquake.<\/p>\n

The quakes, warn catastrophe modeling company Temblor, have placed stress on the Garlock Fault that links the Ridgecrest Faults with the San Andreas Fault. In a blog post, Temblor CEO Ross Stein and Shinji Toda of Tohoku University explained that if the Garlock Fault ruptured in a large shock, \u201cit would likely trigger a San Andreas earthquake north of Los Angeles.\u201d<\/p>\n

A paper on the research has been published in the Bulletin of the Seismological Society of America.<\/p>\n

\u201cIn our study, we developed a new method to forecast future seismicity,\u201d Stein and Toda wrote in the post. \u201cThese forecasts are not earthquake predictions, which have so far proven impossible. Rather, they are probabilistic, framed in the language of chance. We use past seismicity, the stress imparted by recent large and moderate earthquakes and the equations governing how fault friction varies in time and space (\u2018rate-state friction\u2019) to estimate the likelihood of future earthquakes of different sizes.\u201d<\/p>\n

The experts used machine learning technology<\/a> in their analysis, which estimates a 2.3 percent chance of a magnitude-7.7 Garlock Fault rupture in the next year. \u201cThis is 100 times higher than its annual chances in the \u2018UCERF3\u2019 benchmark model for California, which is jointly issued by the [U.S. Geological Survey], the Southern California Earthquake Center, and the California Geological Survey,\u201d Stein and Toda wrote.<\/p>\n

The scientists calculate that if the Garlock Fault ruptured to within about 30 miles of its junction with the San Andreas Fault, \u201cit would raise the probability of a San Andreas rupture extending to the southeast, on the so-called \u2018Mojave section,\u2019 by a factor of about 150.\u201d<\/p>\n

\u201cThat translates into a 50\/50 chance of a San Andreas Mojave section rupture (with a range, 25 percent-67 percent), either immedia<\/a>tely following a Garlock quake, or after some delay,\u201d they added.<\/p>\n

Set against this backdrop, they estimate that the net chance of a large San Andreas earthquake in the next 12 months is 1.15 percent. \u201cWhile small, this probability is 3.5-5.0 times higher than the annual chance of a large San Andreas earthquake in the \u2018UCERF3\u2019 benchmark model for California,\u201d they added.<\/p>\n

Given the small likelihood of a large San Andreas earthquake in the next year, the scientists say no one should panic.<\/p>\n

\u201cBut, as we have seen during the COVID-19 pandemic, low probability chain-reaction events do occur in nature, and when they do, their consequences can be great,\u201d they explained. \u201cIt is the responsibility of scientists to assess the likelihood of such events, and then to bring them to the attention of the public and decision-makers.\u201d<\/p>\n

Seismologist Lucy Jones, who was not involved in the study, described the analysis as \u201celegant\u201d in a tweet, but added that it \u201cassumes a reason for quake triggering that is not consensus.\u201d<\/p>\n

Context. The chance of a San Andreas quake is up slightly,
<\/br>IF a Garlock quake happ<\/a>ens because of Ridgecrest, and
<\/br>IF this model is correct. It’s elegant, but assumes a reason for quake triggering that is not consensus. https:\/\/t.co\/gg2SDahQmV<\/p>\n

\u201cThe possibility of a San Andreas quake AT ANY TIME should already be part of your planning or you shouldn\u2019t be in California,\u201d she wrote, in another tweet.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
