Tools

earthquake_count_events ~1636 tokens
Count matches without event records, or size an earthquake_search_events query. Omitting start_time uses 30 days; pass explicit bounds for historical periods. queryEcho reports applied filters/window; ignoredFilters names unsupported EMSC inputs. Circle and independently optional box edges intersect
earthquake_get_event ~339 tokens
Fetch detail for a specific earthquake by USGS event ID. Returns the same normalized event a search result carries, plus a projection of the analysis products only the single-event response holds: PAGER impact alert and report link, ShakeMap peak intensity and ground motion, DYFI felt-report totals,
earthquake_get_feed ~670 tokens
Fetch a USGS pre-computed real-time earthquake feed by magnitude tier and time window. These feeds are CDN-cached by USGS and faster and more available than the query API — use them for "what's happening now" queries. "all" includes microseisms (M<1); "significant" is a USGS curation based on magnit
earthquake_search_events ~1859 tokens
Search USGS or independent global EMSC seismic catalogs by time, magnitude, depth, area and source-specific filters. Both include non-tectonic events; event_type="earthquake" excludes them on USGS. Circle and independently optional box edges intersect. Unsupported EMSC filters appear in ignoredFilte
