What’s up in earthquake country?
A compelling new report authored by two U.S. Geological Survey (USGS) researchers found that three powerful California faults have been strangely — almost impossibly — quiet for the last 100 years. Digging into the soil around these faults, Glenn Biasi and Kate Scharer found that big, ground-rupturing earthquakes have been a regular occurrence in the temblor-prone land over the last 1000 years.
That’s what makes the last 100 years so unusual.
“We should not see gaps of 100 years,” Biasi said.
This study, published in Seismological Research Letters, is valuable to consider, not just for what it says about the region’s past, but what it could mean for California’s shaky future. Here are the big takeaways. Read more…
