jma_earthquakes

Pack: jma · Endpoint: https://gateway.pipeworx.io/jma/mcp

Recent earthquakes reported by the Japan Meteorological Agency (JMA), including magnitude, maximum seismic intensity (震度, JMA’s 10-step scale: 1-4, 5 Lower, 5 Upper, 6 Lower, 6 Upper, 7), epicenter (Japanese + English where JMA publishes one), and report time. Sourced from www.jma.go.jp/bosai/quake/data/list.json, which JMA keeps as a rolling feed (typically the last few weeks of bulletins, newest first). Filter by minimum magnitude or minimum intensity to cut noise from the very small, frequent events JMA also reports.

Parameters

NameTypeRequiredDescription
limitnumbernoMax events to return (default 20, max 200).
min_magnitudenumbernoOnly events with magnitude >= this value.
min_intensitystringnoOnly events whose max reported intensity is at least this JMA scale value: “1”,“2”,“3”,“4”,“5-”,“5+”,“6-”,“6+”,“7” (5- = 5 Lower, 5+ = 5 Upper, etc.).
