Many states experience tremors and earthquakes. Tuesday afternoon’s earthquake that shook the Mid-Atlantic region, from Rhode Island to the Carolinas, pegged a magnitude of 5.8 and a depth of 3.7 miles. Another earthquake occurred in Trinidad, Colo. The Mineral, Va., tremor was the largest earthquake to affect Washington, D.C., and could be the largest in Virginia’s history, replacing the 5.8 magnitude quake of June 6, 1897. The Northeast may experience another anniversary this weekend if the projected path of Irene holds its course. The models find Irene scraping the Carolinas and striking Cape May, N.J., at 1 p.m. Sunday, then advancing to New York City on Sunday evening. The last time a similar storm visited the Big Apple was 190 years ago and the Great Hurricane of 1821. Fastcast: Hot, stormy.
