In the following plot, the probability of a richter 8 or higher earthquake is plotted per day,
starting from april 26/2010. Day 1 is april 27/2010. The work is based on the data available at the southern california earthquake data centre and USGS. This was processed in Matlab, and is based on work by Mandelbrot and Taleb and extensive monte carlo analysis for 25 million trials of a four year period. I have only plotted the results for the first year.
I hope people find it interesting and maybe useful if you are planning a trip to Southern California.
