# Duaer Earthquakes

Duaer Earthquakes searches the USGS earthquake catalog, newest first. Without dates it covers the last 30 days. Add a place to search a circle around it.

## When to use

- Check recent quakes near a factory, a supplier, or an office.
- List strong quakes in a region and period for a risk report.

## When not to use

- Real-time alerting within minutes. The catalog updates within minutes to hours.
- Other hazards such as fires and storms. Use https://skills.duaer.com/natural-events.md.

## Call

`GET https://api.duaer.com/v1/data/earthquakes?minMagnitude=6&from=2024-01-01&to=2024-12-31`

Header: `Authorization: Bearer <Duaer key>`
