Waiting for "The Big One"
Los Angeles will be struck by a devastating earthquake.... soon. We don't know when but we do know that it will happen. By recording the earthquakes along the San Andreas Fault for nealry the last 200 years it is very apparent that through the 20th century the fault hasn't moved much comapred to the frequent earthquakes along the fault during the 19th Century. Contrary to what many people would think, geologists know that this is a "bad thing" because if the fault is locked, energy is being built up in the fault so that when it moves it will move a lot.
At the American Geophysical Union conference in San Fransisco, geoscientists from the US Geological Survey have been posing the question "is LA ready for a megaquake?"
Read through the article, do you think that they can cope with a shock on the scale predicted?
