Because the
earthquake did not hit densely populated regions and the impact on people was relatively
small, not too
much has been reported about the outcome.
«It could be in
smaller earthquakes, slow slip events, or in a
much larger one.»
Although geologists can use seismic data from large
earthquakes to see features deep in the earth, the shallow subsurface geology of the park has remained a mystery, because mapping it out would require capturing everyday miniature ground movement and seismic energy on a
much smaller scale.
Research suggests that
small quakes immediately raise the risk of a large quake by as
much as a thousandfold, says Thomas Jordan, director of the Southern California
Earthquake Center, though the probability is still only about 1 percent per day and falls rapidly with time.
The
earthquake — estimated at magnitude 9.0 on the Richter scale — occurred in a total area
much smaller than previous large
earthquakes, such as the 8.8 Chilean
earthquake last year, arguing that the slippage was
much greater for the Japan quake, one of the four most powerful
earthquakes on record.
A second possible method — lowering an unstable flank slowly through a series of
small earthquakes — would be
much cheaper but fraught with geologic unknowns and potential dangers.
Yes, albeit on a
much smaller scale than the 2011 Japan
earthquake and tsunami, according to computer models used by a team of researchers, led by seismologists at the University of California, Riverside.
Yam: I mean, we're focused on California
earthquakes, but of course, severe
earthquakes happen all over the world, and I think places, as Haiti demonstrated, even
smaller earthquakes can cause
much greater damage, based on the construction there.
the cause of the accident is the fact that the geopgysicist community (source SciAm in french version) in the 70s was feelin that this could not happens where it happend, because the rift / break (correct me, I'm alien) was supposed to glide nicely with
small earthquake, and quakeless glide (assumed because ther was difference between earthequake constraints relaxed, and total constraint created by usual move)... after that, people discover that ther have been big tsunamis, big
earthquake, and that the theory may be false... but the power plant was built on a pretend safe place, and not beeing sure of the new theory, not
much was done to anticipate a huge tsunami.
