The third principal earthquake, on February 7, however, matched or exceeded the strength and severity of the December 16 event. The shock, whose epicentre was also located near New Madrid, Missouri, shook the region at 3:45 AM and resulted in the destruction of New Madrid. Structural damage also occurred in St. Louis, Missouri, where several chimneys fell because of the ground vibration.
