Geological and Other Natural Hazards

8 hazards · Natural hazards

Slow-onset, sudden, and from the sun.

Earthquake, landslide, sinkhole and avalanche sit beside drought and geomagnetic storms — hazards that rarely make the news until they do, and that an honest assessment still has to address.

Hazard in Geological and Other Natural Hazards, on the established threats & hazards list

Impact
5432112345

Likelihood

Likelihood
3

Possible — Expected occasionally — roughly once in 10 to 50 years (2–10% chance in any year).

Impact
3

Moderate — Notable effects — injuries possible, damage in multiple areas, essential services disrupted for days.

Readiness
4

High — The organization has a well-developed capability to manage this threat or hazard. Plans, personnel, resources, and skills are largely in place, and the capability has been meaningfully tested or demonstrated. Remaining gaps are unlikely to significantly impair performance.

How we can help

How we’d help you prepare for Geological and Other Natural Hazards

  1. 1

    We pull what the national record holds

    NRI ratings where FEMA models Geological and Other Natural Hazards, any declarations, and the drought-relevant climate record. Where nothing models it, we say so.

  2. 2

    We read your plans and studies

    Mitigation plan, geologic or drought studies you already have, so the evidence you own is cited alongside the federal figures.

  3. 3

    You leave with a cited brief

    Likelihood, impact and readiness for Geological and Other Natural Hazards on your own scale, every figure tied to its source, ready for the planning team or the council.

Preparing for Geological and Other Natural Hazards

Give Geological and Other Natural Hazards the profile it deserves, even if it rarely makes the news.

Slow and rare hazards are the ones plans skim. We show what the national record says about yours, and where your plan has to rely on local knowledge instead. A person replies within one business day.
