`count_earthquakes`

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

Count earthquakes matching a filter without returning the events — fast for questions like “how many M5+ quakes in the last month near X”. Same filters as search_earthquakes (time, magnitude, circular area). Keyless.

Parameters

Name	Type	Required	Description
`start_time`	string	no	ISO date/time lower bound. Defaults to 30 days ago.
`end_time`	string	no	ISO date/time upper bound. Defaults to now.
`min_magnitude`	number	no	Minimum magnitude (e.g. 5 for M5+).
`max_magnitude`	number	no	Maximum magnitude.
`latitude`	number	no	Center latitude for a circular search.
`longitude`	number	no	Center longitude for a circular search.
`max_radius_km`	number	no	Search radius in km around latitude/longitude.
