5.1 Earthquake Hits California

An anonymous reader writes "A 5.1 earthquake hit Southern California at 9:09PM local time on Friday. It was preceded by a 3.6 earthquake, then followed by 3.4 and 3.6 quakes, as well as 100+ smaller aftershocks. The United States Geological Survey has a map showing the epicenter. There have been no reported deaths, though roughly 50 people have been displaced from their homes. 'The shake caused a rock slide in Carbon Canyon, causing a car to overturn, according to the Brea Police Department. Fullerton police received reports of water main breaks and windows shattering, but primarily had residents calling about burglar alarms being set off by the quake.'"

      Come, now. We've only had 5 earthquakes in the last day in Oklahoma, and not a one above 3.2. Seriously though, I have to wonder about whether the frequency is a bad thing. Are they earthquakes that would have occurred in the fullness of time, in other words, from plate shift? In that case, the more frequent the better, in my opinion. Rather a 100 small vibrations than one big shock. On the other hand, if the shocks are caused by emptied out caverns underground collapsing, then again, fracking would serve to lessen that by filling the caverns with fluid. Fracking is being used in Oklahoma mostly for forcing out natural gas. So they caverns are already empty. Fracking fluid should prevent rather than accelerate cave-ins.

      As someone who has lived in California for a very long time (probably longer than those seismologists have been alive) and has been through many quakes, my experience tells me that they are indeed mistaken. A 5.1 quake like that is a good thing, because it's small enough that is doesn't cause much damage, but powerful enough that tectonic pressures are released. We might get a few, weaker aftershocks but there is no way that this is leading to a bigger quake.

      There is a theory that an earthquake does two things - it sets the next stress point, and the shaking may loosen and nudge other sticking points. The end result is the first may be a spot that can't handle the newly imposed loads and fail (another earthquake), the second is that even stable areas of the fault now have lubrication and can slip past each other where before they couldn't, forming yes, more earthquakes.

      Unfortunately, there is no way to tell when the next quake will be a big one, a small one, or a devastating one.

      The evidence has been that the number of earthquakes around the pacific rim ("ring of fire") has been increasing because of it.

      It think the end result is pretty much "just continue on with life" - whatever the risk has gone down because of that failure may have increased the risk elsewhere (as in, not in the exact same spot - no one said it couldn't happen a little way down the fault).

      Up here in BC we have an unstable hill that could in theory slide into a lake and cause a huge disaster the likes of which would make the slide in Washington state look like a minor event! There is a whole huge hill that could slip into Harrison Lake, the result would be a major flash flood of a huge portion of Chilliwack BC and a backup of the Fraser river all the way up to Yale and major flooding of lowlands in Richmond.

      The volume of Harrison Lake has no where to go but straight down a short river to the Fraser. There is one study that claims that an earth quake over 5 in the lower mainland of BC could cause the hill to slide, it is very close to a critical slope angle and is huge. The area that would slide is as large as the historic Frank slide that wiped out an entire community in the East Kootneys. So like Naples with Vesuvius the lower mainland of BC could have a major natural disaster that cannot be prevented.
