# p2pquake.seismic.quake_history Search historical JMA earthquake records via the P2PQuake history endpoint. Supports pagination, intensity and magnitude filters, and prefecture filtering for deeper analysis. Returns epicenter name, coordinates, depth, Richter magnitude, max JMA intensity label, domestic tsunami advisory, report type, and observation point count. Use this for trend analysis, seismic risk assessment, or retrieving older events not in the recent feed. Filter examples: min_scale=60 for Shindo 6+ events, min_magnitude=7.0 for major quakes, prefecture=13 for Tokyo area events. Data source: P2PQuake — community-operated JMA relay, open data, no auth required. Agent View of the PolicyLayer registry record for `p2pquake.seismic.quake_history`.

From the tool's own definition: "Search historical JMA earthquake records via the P2PQuake history endpoint. Returns epicenter name, coordinates, depth, magnitude, intensity label." ## Use case AI agents call p2pquake.seismic.quake_history to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
