Missouri averages 27 tornadoes per year but experiences catastrophic outbreak events. The May 22, 2011 Joplin EF-5 killed 161 people — the deadliest single US tornado since 1947. The spring season (April–May) and fall (October–November) are both active. The Ozarks terrain can mask tornado approach until it's very close. Southeastern Missouri sits directly over the New Madrid Seismic Zone. The 1811-1812 earthquakes — estimated magnitude 7.5-8.0 — were felt from Canada to the Gulf and rang church bells in Boston. A comparable event today would catastrophically damage St. Louis, Memphis, and dozens of smaller cities. Missouri buildings were not designed for earthquake loads. The Missouri and Mississippi rivers have flooded catastrophically multiple times — 1993 (the Great Flood), 2019, and numerous other events. St. Louis sits at the confluence of both rivers. Missouri River communities from Kansas City to St. Charles face recurring flood risk. Flash flooding in the Ozarks is fast and deadly.
Occur across most of the state, often embedded in severe thunderstorm lines and tropical systems.

Insurance gaps
Standard homeowner's policies in Missouri exclude flood damage. Flood insurance through the NFIP has a 30-day waiting period — it cannot be purchased when a storm is forecast. Check your declarations page annually to confirm your coverage limits and deductibles.
Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
