`search_earthquakes`

Pack: usgs-earthquake · Endpoint: https://gateway.pipeworx.io/usgs-earthquake/mcp

Search for earthquakes by date range, magnitude, and geographic location. Supports circular area search by lat/lon/radius. Example: search_earthquakes({ starttime: “2024-01-01”, endtime: “2024-01-31”, minmagnitude: 5.0 }) or search_earthquakes({ starttime: “2024-01-01”, endtime: “2024-12-31”, latitude: 35.68, longitude: 139.69, maxradius: 5, minmagnitude: 3.0 })

Parameters

Name	Type	Required	Description
`starttime`	string	yes	Start date in YYYY-MM-DD format
`endtime`	string	yes	End date in YYYY-MM-DD format
`minmagnitude`	number	no	Minimum magnitude (optional)
`maxmagnitude`	number	no	Maximum magnitude (optional)
`latitude`	number	no	Center latitude for geographic search, -90 to 90 (optional)
`longitude`	number	no	Center longitude for geographic search, -180 to 180 (optional)
`maxradius`	number	no	Maximum search radius in degrees from lat/lon (max 180, optional)
