After about a week, the blisters will start to dry up and the rash will start to go away. In severe cases, where the poison ivy rash covers large parts of the body, it may last much longer. Source(s): http://familydoctor.org/839.xml. Insane Â· 9 years ago.
Everything in the bay area, including Silicon Valley, and most of the populated and coastal areas of Southern California are in the high risk zone for the San Andreas and associated fault systems. See Alexander Lee's answer for the map of relative shaking risk in CA. We do not know where the next 'big one' will be.
However, based on some 1895 and 1908 reports by geologist A.C. Lawson, who named the fault, the name was actually taken from the San Andreas Valley. He likely did not realize at the time that the fault ran almost the entire length of California! The worldâs deadliest recorded earthquake occurred in 1556 in central China. It struck a region where most people lived in caves carved from soft rock.
