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

Name	Type	Required	Description
`limit`	number	no	Max events to return (default 20, max 200).
`min_magnitude`	number	no	Only events with magnitude >= this value.
`min_intensity`	string	no	Only 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.).
