I propose a one-day contest.
In the past large earthquakes in the region of Chile which has just experienced
a Mw 6.5 have been followed by unusually strong felt earthquakes in the Central
Plains region of the U.S. and occasionally in California and the western U.S. (see
link below for a more thorough discussion). In three of four cases this has occurred
three days after the Chile earthquake.
That would make the U.S. quake on Easter Sunday - March 31 +/- 1 day.
I am soliciting earthquake predictions for this possible upcoming event in the Central or
western U.S. for this contest.
The rules will be the same as other contests, but the earthquake predicted
must occur between 00 UT on March 30 and 23:59 on April 1 to be counted
for judging in the contest. Forecasts, however, may be for any time period, but
should include the 31st of March.
I'll send a large chocolate easter egg to the winner.
