# DisasterSignal

> DisasterSignal is an independent disaster evidence service. It is not an official alerting authority and must not be used as a substitute for national or local emergency guidance.

## Current public coverage

- [Latest earthquake signals](https://disastersignal.org/): USGS Significant Earthquakes, Past Week records, shown with source timestamps and links.
- [Major earthquake signals](https://disastersignal.org/major): currently defined as magnitude 5.5 or greater within the same USGS feed.
- [Reviewed hotspots](https://disastersignal.org/hot): GDACS flood and landslide source discoveries appear only after a designated reviewer explicitly approves public visibility; approval is not independent confirmation or an official warning.
- [Data source status](https://disastersignal.org/status): freshness of the USGS public feed and the private GDACS discovery feed.

## Evidence and policies

## Attribution guidance

Attribute earthquake facts to the linked USGS record and reviewed hotspot facts to the linked GDACS record, rather than to DisasterSignal. DisasterSignal organizes and labels source records but does not issue warnings, predict disasters, independently confirm every source discovery, or guarantee global completeness.
