Multi-peril hazard API

Fourteen natural-hazard scores.
One API call.

Petrel scores any point on Earth’s land for landslide, avalanche, earthquake, windstorm, extreme heat, extreme cold, frost, lightning, soil erosion, hurricane, drought, volcanic eruption, tsunami, and storm surge — each a calibrated 0–1 peril score on the same 90 m global grid. Present-day hazard, documented methods, no sales call.

Most hazard APIs stop at one country or one peril. Petrel is the same catalog everywhere — the grid in Osaka is the grid in Oslo and Ohio.

Four endpoints. The whole surface.

GET/v1/score
Every live peril for one point, in one call.
Query params lon, lat, and an optional hazards filter. Returns a calibrated 0–1 score per peril, all on one scale.
POST/v1/score/batch
Portfolio screening — up to 10,000 points per call.
JSON body of {id, lon, lat} records; one row per point with every requested peril inline.
GET/v1/return_level
Return-period values: hurricane gust + drought severity.
Hurricane rp50–rp500 peak gust (m/s, 10,000 years of synthetic tracks, six basins). Drought rp5–rp100 SPEI-12 severity (σ, 85 years of ERA5 via regional frequency analysis).
GET/v1/catalog
STAC catalog with COG asset URLs for every release.
Browse vintages and peril versions; compatible with pystac-client. Assets served from data.petreldata.io.

See how every score is built.

Every peril ships with its model, inputs, and validation documented — per hazard, per release.

Landslide

XGBoost on an 80,000-event global inventory, spatially blocked cross-validation — AUC 0.97.

Methodology →

Earthquake

GEM 2023 global seismic hazard (475-year PGA) modulated by Vs30 site amplification.

Methodology →

Windstorm

The 100-year gust from GEV fits on ERA5 reanalysis extremes, 1991–2020.

The honest FAQ.

Do you cover flood?

No — there is no live flood product today. What is live: landslide, avalanche, earthquake, windstorm, extreme heat, extreme cold, frost/freeze, lightning, soil erosion, hurricane, drought, volcanic eruption, tsunami, and storm surge.

Is this a cat model?

No. Petrel ships hazard scores — plus hurricane return-period peak gusts — not loss curves or event sets.

Do you model climate scenarios?

No. Scores are present-day hazard, built from recent climatology and observations. If you need 2050 scenario projections, we are not that.

What's the demo limit?

The public demo at petreldata.io/try is rate-limited per day, no signup. A free API key lifts you to the full 1,000 calls/mo quota.
