The Challenges and Perils of Earthquake Prediction: Part 4. What’s New with New Madrid?
Surprisingly, the New Madrid seismic zone is considered as high of a seismic risk than the San Andreas Fault zone in California. This section highlights the apparent inconsistency with present estimates of seismic risk in the U.S. and Japan. Estimates of earthquake recurrence intervals can also be obtained from paleoseismology: evidence of prehistoric earthquakes preserved in the rock and sediment record.
