The report on the 2002 earthquake in the Mississippi Delta says the quake registered a 3.1 magnitude and occurred at a depth of 3.1 miles.
The report by Charles T. Swann and Terry L. Panhorst stated the cause of the quake has not been identified.
The earthquake occurred on Saturday, Oct. 26, 2002. No injuries or significant damage were reported.
The eastern and western boundaries of the earthquake could not be determined, according to the report, because of the sparse population and many people were away from home on that Saturday.
The largest earthquake recorded in Mississippi occurred in 1931 near Charleston.
Although modern equipment was not available to measure the epicenter of the earthquake, it was estimated to have a magnitude of five.
Panhorst and Swann say efforts should be made in the Delta areas to evaluate the possible impact on buildings, utilities and other critical structures.
