DeSoto County is the northernmost Mississippi county bordering Memphis Tennessee and Shelby County Tennessee. The county sits directly on the New Madrid Seismic Zone — a major earthquake would cause catastrophic damage across the region. Multiple tornadoes have struck DeSoto County. The county has been one of the fastest growing in Mississippi as Memphis suburbs expand south. The Wolf and Coldwater Rivers create flooding risk.
