A recent study conducted on the New Madrid Seismic Zone by investigators at the US Geological Survey (USGS) has revealed that the earthquake activity currently being reported in the area, between Memphis and St. Louis, does not represent the aftershock pattern of previous tremors.
Some scientists have suggested that large earthquakes which have occurred some 200 years ago are still triggering aftershock, which is what we are seeing today. However, the new study provides that this explanation is flawed, showing that aftershock behaviors cannot be identified in New Madrid.
