The 2033 New Madrid earthquake was a very rare, very destructive earthquake in the central New Madrid, Illinois, area. The earthquake was a magnitude 8.4Mw, tying the record set in 1811 for the state's strongest earthquake on record. It lasted 3 minutes, 17 seconds, and was responsible for 9343 deaths, 14,313 injuries, and $229 billion in damages. The thrust fault was thrown up so violently that the Mississippi-Missouri river flowed backwards for 3 years after the event, whilst the land slowly subsided to its pre-quake levels, allowing the river to flow its normal cours again. Several aftershocks, including 7.3Mw aftershock the following year added to the already extreme damages, adding to the numbers either killed or injured byt he event over the next 15 years following this powerful tremor.
