Japan Earthquake, Tsunami & Weather Warning Alerts (JMA Official Feed)

Get Japan disaster alerts as clean JSON straight from the Japan Meteorological Agency (JMA)'s official disaster-prevention XML feeds (気象庁防災情報XML) – earthquakes, tsunami warnings, weather warnings by municipality and volcanic eruptions – with English field names, prefecture filters and an only-new mode for scheduled monitoring.

• Earthquakes – origin time, epicenter, latitude / longitude, depth, magnitude, maximum JMA seismic intensity (shindo, with English labels such as "5 Lower"), intensity per prefecture, tsunami risk message
• Tsunami – major tsunami warning / tsunami warning / advisory / forecast per coastal area, expected arrival time and maximum height
• Weather warnings – heavy rain, flood, landslide, storm, snowstorm, heavy snow, high waves, storm surge… per municipality, with level (emergency / danger / warning / advisory) and English names, including the new 危険警報 (danger warning) level
• Volcanoes – eruption observations (plume height, crater) and Volcanic Alert Level changes
• Only new alerts: remembers what it already returned, so a schedule every 5–10 minutes gives you just the new earthquakes and the municipalities whose warnings changed
• Official feeds only – no scraping, no API key, runs in seconds

Typical uses

• Logistics & supply chain – know which prefectures and factories are under heavy-rain or snow warnings, or were shaken by an earthquake, and trigger a check.
• Travel & hospitality – alert guests and staff; add a disaster banner for affected areas.
• Insurance & risk – log every earthquake with intensity ≥ 4 or every emergency warning for claims triage and exposure reports.
• Business continuity (BCP) – send Slack / Teams / email alerts via Apify integrations or webhooks when your sites are affected.
• Apps, dashboards and AI agents – a clean English JSON layer over the Japanese-only JMA XML.

Input

{
  "alertTypes": ["earthquake", "tsunami", "weather-warning"],
  "lookbackHours": 1,
  "prefectures": ["Tokyo", "Kanagawa", "Osaka"],
  "minIntensity": "3",
  "warningLevels": ["emergency", "danger", "warning"],
  "onlyNew": true
}

• Schedule: create an Apify schedule every 5–10 minutes with lookbackHours: 1 and onlyNew: true, and connect a Slack / email / webhook integration to the run's dataset.
• Reports / backfill: lookbackHours up to 168 (about 7 days, the length of the JMA long-term feed).

Weather warning (one row per municipality):

{
  "type": "weather-warning",
  "reportTime": "2026-09-26T09:41:00+09:00",
  "prefectureEn": "Hokkaido",
  "municipalityJa": "釧路市釧路",
  "municipalityCode": "0120601",
  "highestLevel": "warning",
  "warningsEn": "Heavy rain Warning",
  "activeWarnings": [{ "nameJa": "大雨警報", "nameEn": "Heavy rain Warning", "level": "warning", "status": "issued" }],
  "office": "釧路地方気象台"
}

Tsunami rows list areas with level (major-tsunami-warning, tsunami-warning, tsunami-advisory, tsunami-forecast), firstArrival and maxHeightM. Volcano rows have volcanoJa, alertLevel, kindJa, plumeHeightAboveCraterM.

Notes

• Earthquake reports for one event (intensity flash → hypocenter → details) are merged into one row with the most complete data.
• Weather-warning reports are issued per forecast area and always contain the full current state; the Actor keeps only the latest one per area.
• Place names are in Japanese as published by the JMA; prefectures are also given in English.
• This is not an official warning service. Feed delivery can be delayed or stopped for maintenance. For life-safety decisions follow the JMA, local governments and broadcast warnings.

Pricing

Pay per event: $0.002 per alert row plus the tiny Apify start fee. A 10-minute schedule for a few prefectures usually returns only a handful of rows per day.
