Newsletter: Unprecedented insight into how earthquakes start, via new research
Good morning, and welcome to the Essential California newsletter. It’s Wednesday, Aug. 21, and I’m writing from Lodi.
It is almost surprising, given the near infinite amount of things that you can bet on online in 2019, that no bookmakers appear to be offering odds on when the next big earthquake in California will occur.
Perhaps society isn’t as far gone as one might fear, if we’ve yet to offer up that particular brand of opportunistic ugliness. (There are, however, plenty of options to bet on the San Jose Earthquakes, a Bay Area Major League Soccer team. It should also be noted that sports betting remains illegal in California.)
But bookies aside, the odds of not if but when are a mental calculation all Californians constantly make as they build their lives in this seismically active state. For researchers, the ability to reliably predict the next major quake remains the “Holy Grail of earthquake science.”
Unfortunately, we are no closer to predicting the exact timing and epicenters of big earthquakes. But there is new research that provides unprecedented insights into how seismology works, as my colleague earthquake reporter extraordinaire Rong-Gong Lin II detailed in a story published Tuesday.
“One of the biggest questions in earthquake seismology is how earthquakes get started,” as seismologist Daniel Trugman, the lead author on a new study, told Lin.
Trugman’s research reveals that the vast majority of earthquakes we feel come soon after smaller ones, with even moderate quakes likely to occur after a series of less-powerful ones. The results of the study suggest, as Lin writes, “that it’s possible that all moderate and large quakes are preceded by something smaller, but getting to that conclusion would require more studies.”
