Enter an address. Credible Risk looks it up in the official government databases — faults, earthquake design values, flood, wildfire, landslide, dam inundation, tsunami and coastal — and shows you the exact query behind every answer.
If a source is down, it says so. Nothing is guessed.

Click any answer and you get the government record behind it — the service, the exact query, and the time it ran.
Click any determination and open the exact query — FEMA, CGS, USGS — against the live service, timestamped to the second.
Appendix A of every report is a determination log — service, layer, queried-at, exact URL — that any reviewer can reproduce line by line.
Every API response carries the same sources, so anything built on Credible Risk can show its work too.
Each one is looked up live in the agency's own database at the moment you search — not read from a stored copy.
Nearest active and Quaternary faults with distance and bearing, estimated Mmax (Wells & Coppersmith), historic M4.5+ seismicity since 1900, and a terrain cross-section to the nearest active trace.
Official CGS regulatory zones — Alquist-Priolo, liquefaction, earthquake-induced landslide — plus ASCE 7-22/16/10 and ASCE 41 design values with response spectra, by site class and risk category.
USGS Qfaults · USGS Design Maps · USGS ComCat · CGS EZRIEffective FIRM flood zone, Special Flood Hazard Area status, and static base flood elevation at the point.
FEMA National Flood Hazard LayerFire Hazard Severity Zone class from the 2024–25 maps, labeled to show whether the zone is adopted by the state or still only recommended locally.
CAL FIRE FHSZ (2024–25)Deep-seated landslide susceptibility class 0–10 at the point — distinct from, and alongside, the CGS regulatory zone check.
CGS MS58Every approved dam-breach inundation boundary the site falls within — dam name, hazard class, and failure scenario.
DSOD / Cal OES approved boundariesPresent-day 100-yr coastal storm exposure and the 100 cm SLR planning scenario — scenario IDs printed on the report.
USGS CoSMoS · NOAA SLROfficial state tsunami hazard area determination, read from the evacuation attribute — membership alone is never trusted.
CGS Tsunami Hazard AreaSeismic screening, ASCE design values, FEMA flood and regional risk context cover every U.S. address. The California state programs run at full depth in California — and outside their extent the screening says not covered, never “no hazard.”
Screen one site, rank a list of them, generate the report, or check a report someone else wrote.
Drop a pin, paste coordinates, or search an address. Faults, zones, design values and all seven hazards resolve live — with two transparent indices that show their work.
Paste a program of sites and get them ranked by screening priority — seismic-only or full multi-hazard — with a CSV your PM can drop straight into the proposal.
A print-ready draft with fault-map, terrain-section and response-spectra figures, per-hazard determinations with citations — and a determination log any reviewer can re-run.
Verify a report someone else wrote: every stated determination re-derived live, with the sentence it came from and the query that answers it. See how →
Fault search, AP check, design values, historic seismicity, regulatory zones, FIRM lookup, FHSZ, dam boundaries — the routine compilation that opens every study, compressed to a screening you can hand a senior reviewer. Spend the fee on judgment, not lookups.
Senior geotechnical engineers went through the method line by line, and every correction they gave us shipped.
seismic 30 · flood 20 · wildfire 20 · landslide 10 · dam 10 · coastal 10. Nothing proprietary hides inside the number, so a reviewer can recompute it by hand.service unavailable — not scored, and the composite is flagged partial. Outside a program's coverage it reports not covered — never “no hazard.” Weights never silently rescale. A determination is never invented to fill a box.Drop a consultant’s PDF and Credible Risk reads the determinations it states — each with the sentence and page it came from — then re-derives every one against the live source. What comes back is the report’s own words beside the government query that answers them.
Extraction turns prose into typed claims and stops there. Every verdict below it is a deterministic comparison against USGS, FEMA, CGS and CAL FIRE, under published tolerances.
A flood zone can be correct and still omit the regulatory floodway inside it. Those get their own verdict — Incomplete — because a reviewer’s question is whether the report is correctly scoped, not just correctly typed.
One click gives you a Word memo — findings, quotes, receipts, determination log — or a link that re-runs the whole check live in the recipient’s browser, with no login.
Every hazard, every index, one call — with the receipts included. Built for due-diligence platforms, underwriting pipelines, and portfolio monitoring: the physical-risk layer your product shouldn't have to build.
Credible Risk is built shoulder-to-shoulder with the practices that use it — expert review goes in, product ships back out in days.
