NATIONAL CATHEDRAL DAMAGED IN QUAKE

It was the strongest earthquake to hit Virginia since at least 1897 (for which earthquake magnitudes are estimated) and apparently the strongest quake to hit east of the Mississippi River since a 5.9 quake struck in Indiana in 1983, according to a site hosted by Michigan Technological University.

The strongest earthquake recorded on the East Coast hit Charlestown, S.C., in 1886 with an estimated magnitude of 6.8, resulting in more than 60 deaths and extensive damage.
