Oklahoma is the heart of Tornado Alley. The May 3, 1999 F5 struck Moore with winds of 301 mph — the highest ever recorded. Moore was devastated again in 2013. Oklahoma City has been hit by significant tornadoes more times than any major US city. The spring season (April–May) is peak, but violent tornadoes can occur November through March as well. Oklahoma's grasslands are tinderboxes in drought years. The spring fire season (March–May) and fall (October–November) can produce fast-moving fires that outrun vehicles. Western and central Oklahoma are the most exposed. Drought conditions — increasingly common — extend the fire season and increase intensity. Oklahoma experienced an earthquake epidemic driven by oil and gas wastewater injection wells. The state went from 1-2 magnitude 3.0+ quakes per year before 2008 to over 900 in 2015. Injection rates have been reduced but seismic risk remains elevated statewide — particularly in central Oklahoma. Buildings here were not designed for earthquake loads.
Occur across most of the state, often embedded in severe thunderstorm lines and tropical systems.

Insurance gaps
Standard homeowner's policies in Oklahoma 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
