A newly discovered fault beneath the Salton Sea may change the way scientists look at the southern San Andreas fault and the growing potential for a major earthquake centered in that region. But after campaigning for the White House on a pledge to “follow the science,” Biden found himself uncharacteristically ahead of it with that lofty pronouncement. The main fault involved appears to be the Westmoreland fault, which is not long enough for a quake much bigger than magnitude 5.8, famed seismologist Lucy Jones said in a series of tweets over the weekend.
