Aerial Image Shows Fracture in Crater of Bali Volcano Mt. Agung

TEMPO.CO, Jakarta - The latest aerial photograph of Bali volcano Mount Agung shows a much wider area of fracture at its crater. The image was taken by a drone flown on top of the mount’s crater by a drone team from Gadjah Mada University (UGM) and the National Disaster Mitigation Agency (BNPB) on Thursday, October 19.

“From the previous satellite imagery taken by Planet Scope on October 11, the fractures were only visible on its east side. The drone photographs this afternoon showed that the fractures on the eastern side were considerably larger,” said BNPB Head of Data Information and Spokesman on Thursday, October 19.

The photographs were taken by a three-man team using two - UGM-made - Buffalo FX79 drones flown at the height of 4,000 meters during an hour aerial session. The whole of Bali volcano Mount Agung was spatially mapped by the team through several stages that compiled 400 images which would be made into a three dimensional model of the volcanic mountain.

Around 400 images taken by the drone show that a small rift in the crater’s southeast area has started to emerge followed by a denser sulfuric fume, which shows an ongoing process of volcanic resurfacing.

Non-harmonic tremors have been recorded for three times, as well as 58 shallow volcanic quakes and 104 deep volcanic quakes, and also 17 tectonic quakes. The team concluded that the number of Bali volcano Mt. Agung's quake activity has generally dropped.
