Understanding tsunami events
Ocean waves generated by earthquakes, landslides or eruptions. A tsunami is a series of waves, and the first is often not the largest. Where the shaking is strong enough to make standing difficult near a coast, the correct response is immediate movement to high ground without waiting for an official alert.
How severity is rated
Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Moderate. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for tsunami situations
- Keep a safe distance from the affected area and let emergency services work unobstructed.
- Rely on official local channels for instructions and avoid amplifying unverified reports.
- Prepare a basic emergency kit: water, medication, torch, power bank, documents and cash.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from GNEWS and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
