Yes, how about a histogram of the earthquake intervals? Is table 8 on page 102 of: http://pubs.usgs.gov/pp/pp1661f/pp1661f_text.pdf http://pubs.usgs.gov/pp/pp

Yes, how about a histogram of the earthquake intervals? Is table 8 on page 102 of: http://pubs.usgs.gov/pp/pp1661f/pp1661f_text.pdf http://pubs.usgs.gov/pp/pp1661f/pp1661f_text.pdf ...the raw data we are looking for? That data looks to have a mean of 530 years, and a standard deviation of 262 years, although it isn't very normal looking (well there are only 18 samples after all, so maybe it isn't too bad). See the histogram I plotted at: http://imgur.com/4fv7jDJ http://imgur.com/4fv7jDJ ...any sources of data with the lower average for the interval? Here's the raw data that I used: intervals = [250, 305, 446, 311, 982, 492, 415, 665, 661, 1189, 508, 715, 443, 548, 733, 195, 117, 577] ...as for the disagreement on the intervals, the only thing I could find was: http://www.seattletimes.com/seattle-news/how-often-does-cascadia-fault-rip-scientists-disagree/ http://www.seattletimes.com/seattle-news/how-often-does-casc...
