The Infamous Dr. Browning's New Madrid Prediction

"We owe him (Iben Browning) a debt of gratitude," New Madrid Mayor Dick Phillips said Friday. "I respected the man's intelligence.

Based on geologic evidence there were at least 8 prehistoric earthquakes in the Wabash Valley Zone over the past 20,000 years with estimated magnitudes of 6.5 to 7.5.

Earthquakes east of the Rockies are typically felt over a broader region than in the western United States. Adjacent to Wabash Valley sits the fault line whose past predicts a dire future, the sleeping giant, the New Madrid Fault or New Madrid Seismic Zone (NMSZ).
