Ash emissions from Raung volcano reach 4.6 km (15 000 feet) a.s.l., Indonesia

Volcanic ash emissions were reported at Raung volcano, Indonesia, with ash rising to an altitude of 4.6 km (15 000 feet) above sea level. The latest observation of volcanic ash was recorded at 17:40 UTC on June 15, 2025. The event was tracked using Himawari-9 satellite data and ground reports from CVGHM.

The volcanic ash cloud extended from the surface up to FL150 (4.6 km, or 15 000 feet), moving north at approximately 10 knots. Ongoing ash emission was referenced in recent ground observations at 23:28 UTC on June 14, 2025. However, volcanic ash was not identifiable in the most recent satellite imagery due to meteorological cloud cover, and the height and movement of the plume were extrapolated from model guidance and previous ground and satellite reports. The current Aviation Color Code is Orange.

There is no recent summary of Raung volcano’s activity in the latest Smithsonian / USGS Weekly Volcanic Activity Report. Please consult official agencies for further updates on this event.

Raung is a large stratovolcano located in East Java, Indonesia, notable for its broad summit caldera. The primary hazards associated with Raung include ashfall, which can impact nearby towns such as Banyuwangi and Bondowoso, as well as the risk of pyroclastic flows and volcanic gas emissions. Due to its frequently active summit, Raung poses aviation hazards and potential health impacts for populations in surrounding areas.
