Open source & free forever

Real-time disaster monitoring, open and free

SentryAtlas aggregates live disaster data from four trusted public sources onto a single interactive map. Earthquakes, wildfires, floods, storms — see it all at a glance.

Earthquakes · Wildfires · Floods · Storms · Volcanoes · Cyclones · Hurricanes & 6 more

One map. Every disaster. In real time.

SentryAtlas continuously pulls data from government and scientific agencies around the world, normalizes it, and plots it on an interactive heatmap you can filter, zoom, and explore.

Global Coverage

Aggregates data from 4 independent sources covering every continent and ocean. Earthquakes in Japan, wildfires in California, floods in Europe — all in one place.

13 Event Types

From earthquakes and wildfires to hurricanes and icebergs. Filter by type, time range, and viewport to see exactly what matters to you.

Trusted Data

Every event comes from a verified public agency. No user-submitted data, no social media scraping — just authoritative government and scientific sources.

Fully open source

SentryAtlas is built in the open with a Go backend, a Next.js frontend, and MapLibre GL for map rendering. No API keys required, no paywalls, no tracking.

Contributions, issues, and ideas are welcome.
