![]() ![]() Then that would then recede, then it would grow again, and then it What is happening is that the river would flood into the basin where the Salton Sea exists, and it would build a very, very large lake. I'm so glad I got the chance to talk to you today. But there's a little bit of misconception. ![]() The Colorado river water also provided a load, a geological load that seems to in the past have triggered a number of smaller earthquakes. ![]() That could trigger earthquake ruptures beneath the lake.ĬAVANAUGH: There's a second part, and it has to do with the diversion of the Colorado river. KILB: When you have a very large lake, very, very large, the Salton Sea is just a mere fraction of what was there in the past, when you have the large lake, that can put an enormous amount of pressure on the bottom of the lake. It's a two step sequence that our research is looking at. KILB: What our research shows is that the incidence of lake holding can trigger faults beneath the sea, those in turn could trigger the San Andreas fault. Doctor Kilb, hello.ĬAVANAUGH: What does your research indicate might be delaying a quake? Joining me now is doctor Debbie Kilb, seismologist from Scripps institution of oceanography. And it may have a lot to do with human interference. A new study by researchers at Scripps institution of oceanography provides an explanation as to what may be causing the delay. Many say this is a hundred years overdue. Seismologists have long predicted that the San Andreas fault is ready to create a massive quake. We've been warn forward years about the big one coming to Southern California. And a report on how San Diego's LGBT community has become a political force in San Diego. On today's show, we'll hear about testimony before the county board of supervisors challenging how the board draws up its new voting districts. Proposed San Diego County voting districts are challenged by the ACLU. Opinions expressed by guests during interviews reflect the guest’s individual views and do not necessarily represent those of KPBS staff, members or its sponsors.ĬAVANAUGH: There are no concerns about a megaquake for Southern California. Please refer to the media file as the formal record of this interview. This is a rush transcript created by a contractor for KPBS to improve accessibility for the deaf and hard-of-hearing. ![]()
