How much bigger is the biggest earthquake ever recorded (M9.5) compared to the Northridge earthquake (M6.7) in terms of energy release, not amplitude on a seismogram. *
Watch the "Map View" Great Shake Out animation found by clicking the link below. Why might the intensity of earthquake waves seen in the movie change as the rupture moves along the San Andreas Fault? *
Liquefaction is a scenario seen in the video at the link below. An alternate link is provided in case you are at school and cannot access YouTube. What causes liquefaction and what are the hazards associated with it? *
What can be one of the largest indirect earthquake hazards due to ruptured gas lines? *
How can seismic gaps and paleoseismology be used to issue earthquake probability estimates? *

How does the probablility of an earthquake in La Canada change as earthquake magnitude changes? How does the probability of an earthquake change as time changes? *
Use the following link to test the probabilities as a function of time and magnitude. Input zip code 91011 instead of using latitude longitude: http://geohazards.usgs.gov/eqprob/2009/index.php
