Dukono Volcano Ash Advisory: Volcanic ash has been detected at an altitude of 7,000 feet (2,100 meters), moving northeast as of December 20, 2025, at 0040 UTC.
As we dive into this ongoing volcanic activity, it’s essential to understand the implications of such eruptions. The Volcanic Ash Advisory Center (VAAC) based in Darwin issued warnings about the ash plume resulting from Dukono's explosive behavior. This advisory is crucial for aviation safety and public awareness, especially in regions prone to volcanic activity.
The details of the advisory are as follows:
- Advisory Report Number: 2025/1063
- Date and Time of Advisory: December 20, 2025, at 01:00 UTC
- Location: Dukono Volcano, Indonesia (Coordinates: N0142 E12754)
- Source Elevation: 1,229 meters above sea level (AMSL)
- Verification Source: HIMAWARI-9 satellite imagery
- Eruption Observations: The volcanic ash was reported to reach flight level 070 at 0040 UTC, with the ash cloud detected moving northeast at approximately 15 knots.
The ash cloud was mapped with coordinates indicating its spread:
- Current Observed Ash Cloud: From surface level up to 7,000 feet, covering points including N0140 E12752, N0142 E12750, N0203 E12806, and more.
- Forecast for Ash Cloud Movement: Predictions show continued movement, with forecasts extending at 6-hour intervals detailing potential ash locations.
The latest satellite imagery confirms the presence of volcanic ash, although meteorological clouds are obscuring some areas. The height of the ash plume and its forecast trajectory are based on both recent eruptive activities and model predictions, which assist in anticipating how the situation may evolve.
Next Advisory: The next update will be issued no later than December 20, 2025, at 07:00 UTC.
In previous updates regarding Dukono Volcano, the Center for Volcanology and Geological Hazard (CVGHM) reported that the eruption remained active on December 18, 2025, where ash and gas emissions were consistently observed. The ongoing explosive activity has been a point of concern for local residents and authorities alike.
For those interested in exploring volcanic landscapes, Dukono is known for its complex eruptions since the early 20th century. Tours are available for those wishing to trek through the stunning Molucca Sea region while experiencing the natural beauty and geological wonders.
