Comparative safety

Tornado vs earthquake preparedness

If you live in the central US, you might face both. Preparedness overlaps more than you'd think — but the specific tactics differ.

Where they overlap

Water storage (14+ days) — same for both.
Non-perishable food — same.
Battery-powered radio and flashlight — same.
First aid kit — same.
Prescription medication reserve — same.
Documents in waterproof binder — same.
Communications plan with out-of-state contact — same.
Cash reserves — same.

Where they differ

Warning time

Tornado: seconds to minutes. Earthquake: zero (some seconds with ShakeAlert).

Where to go

Tornado: interior lowest floor. Earthquake: Drop, Cover, Hold under sturdy furniture.

Home retrofit

Tornado: storm shelter. Earthquake: bolt to foundation, cripple wall bracing.

After-event risk

Tornado: debris, wires. Earthquake: gas leaks, aftershocks, fire.

Structural failure mode

Tornado: roof lifts off, walls collapse outward. Earthquake: floors pancake, chimneys fall in.

Insurance

Tornado: standard homeowners. Earthquake: separate policy required.

For central Kentucky / Tennessee / Arkansas (New Madrid + Tornado)

The New Madrid seismic zone includes portions of MO, IL, KY, TN, AR — all heavy tornado country. A 100-year event is overdue.

Bolt water heater to studs (earthquake).
Store water on lowest interior floor (both).
Keep hardhat + closed-toe shoes bedside (both).
Anchor bookcases and heavy furniture (earthquake).
Interior safe room / basement corner (tornado).
Learn to shut off gas (earthquake).
Weather radio + earthquake alert app (both).

For California + occasional tornado

California averages 10 tornadoes/year, mostly winter cold-core. Weak but real. Preparedness is straightforward if you're already earthquake-ready.

For Pacific Northwest (Cascadia + rare tornado)

Cascadia subduction zone poses M9 risk. Tornadoes are rare and weak. Focus preparedness on earthquake.

The 2-week supplies recommendation is because post-Cascadia, help may take that long.

The one thing that's different

For earthquakes, we don't know when.

For tornadoes, we get a warning.

That difference drives everything about how you plan. Earthquake preparedness is about resilience — surviving weeks without infrastructure. Tornado preparedness is about the next 15 minutes — getting to shelter fast.
