I was curious what the chances for success in the contest are
given the historical activity following the 34 earthquakes in
northern Chile of Mw>=6.5 in the past century. Here are some
approximate summary statistics for those who would still like
to make a prediction.

Following earthquakes of Mw>=6.5 in Northern Chile, the following
approximate probabilities for a felt event occur based on historical
coincidence of Chile and subsequent events:

Central Plains (Oklahoma, Nebraska, So. Dakota, Kansas,
Illinois, Missouri, New Madrid);
within 10 days: 50%
within 15 days: 65%

Southeast Central U.S. (Tennessee, No. Carolina, Virginia,
Pennsylvania):
within 10 days: 28%
within 15 days: 30%

New England
within 10 days: 12%
within 15 days: 18%

New England
within 10 days: 12%
within 15 days: 18%

Ontario/Quebec
within 10 days: 25%
within 15 days: 36%

Western Plains (Colorado, Wyoming, New Mexico)
within 10 days: 12%
within 15 days: 12%

California/Mexico Border (M>=5.5)
within 10 days: 10%
within 15 days: 10%

Dixie Valley Nevada area (M>=6.0)
within 10 days: 10%
within 15 days: 10%

Following are the events that ocurred after strong Chile
events in the U.S. dates, magnitudes and time delays between
Chile and subsequent U.S. shock for your interest.
