*For Saturday, 5 April 2008.

LEGEND for OVERVIEW: Size = My surety of area for quake.
Red Circle = Probable quake to STRONG quake.
Triangle = Very Strong/Stronger quake (Usually takes extra days).
Blue Circle, etc. = Uncertainty of symptom area for probable quake.
Gold Circle = Volcanic symptom.
(If I find a matching symptom in my database I will give a
probable magnitude.)


Places to watch.

Good luck to all.

Swarm of small quakes in Tennessee puzzles scientists

Monday, April 7, 2008

In less than 24 hours, a swarm of 28 small earthquakes was recorded near Ridgely, Tenn., a city 109 miles southeast of Cape Girardeau.

Ridgely is at "a junction of two major faults in the New Madrid seismic zone," said Gary Patterson, geologist and spokesman for the Center for Earthquake Research and Information at the University of Memphis.

Multiple earthquakes are common near Ridgely, he said, but are limited to four or five events. Every 20 years or so, he said, a big swarm, such as the one that started Saturday, occurs.

He said it is not clear if the weight of water from recent rains caused the quakes, but scientists are studying the possibilities.

"Certainly the occurrence of earthquakes is controlled by the amount of overburden — how much weight is above it," he said. But swarms have occurred in both wet and dry weather.
