JMA Probes Possible Tsunami After Major Semeru Eruption in Indonesia
The agency is evaluating whether atmospheric pressure waves from the blast produced waves that could reach Japan.
Overview
- A large eruption at Indonesia's Semeru volcano occurred around 18:20 JST on November 19, according to the Japan Meteorological Agency.
- Officials are investigating whether the event generated a tsunami that might affect Japanese coasts.
- If a tsunami was produced, the earliest potential arrival in the Okinawa region was estimated at around 21:30 JST.
- The review focuses on pressure-wave transmission from the eruption, a mechanism known to induce sea-level disturbances.
- Japanese media are relaying JMA updates, and no tsunami impact on Japan has been confirmed as of the latest reports.
