The map at right depicts a 3.2 magnitude Wyoming earthquake which was reported
as happening at 2:40 PM EDT today, and then within an hour, mention of it
disappeared from the USGS seismic reporting site. Oddly enough, while the "Red
Square" shown has disappeared, some data on the quake is still available Online. If
and when that URL no longer works, here is the information shown there now: Recent Earthquake Activity in the USA
