Excellent article. Thanks!
When I first moved to Maryland, there was a short series of essentially "unexplained" Richter 2-3 earthquakes in eastern Howard County. The geologists cited a fault system that runs through Howard County and northern Baltimore County. I wonder if the fault could be related to the southern Chesapeake Bay impact site. Probably not, but a possibility, I guess.
Wild speculation on my part-I live in South Central Texas,and a few mild earthquakes occur south of San Antonio from time to time. There has also been speculation that the western half of the Gulf of Mexico(the Texas coastline and the Yucatan Peninsula)is actually the remnants of a big meteor strike. Wonder if there's a connection.
