Pat Shingleton for Tuesday, April 23, 2013

Earthquakes have made headlines from Anchorage to Mexico City. On April 22, 2009, a magnitude 3.8 earthquake was recorded near Centreville, Ala., about 40 miles southwest of Birmingham. Another quake shook Birmingham on April 23, 2003, measuring 4.5 on the Richter scale. Louisiana has experienced earthquakes. On Oct. 19, 1930, one rattled Napoleonville with effects reported in Des Allemands, Donaldsonville, Franklin, Morgan City and White Castle. Residents reported overturned objects, shaken trees and cracked plaster. Other area quakes include a magnitude 3.8 reading near Greenville, Miss., on June 4, 1967. On Nov. 19, 1958, one shook houses and rattled windows in Baton Rouge. As noted in previous columns, LSU geologists at LSU note the Baton Rouge fault is a growth fault, not resulting in measurable earthquakes. Fastcast: More clouds.
