On Thursday, October 19, a surveillance drone detected that the fracture in the crater of Agung volcano, Bali, Indonesia had widened since the satellite image taken Wednesday. While seismic activity under Agung is still increased, the seismic energy continues to decline. Authorities are urging people to stop spreading fake news, adding Bali is safe four tourists.
"The fracture is located on the eastern side of the volcano," BNPB's spokesman Sutopo Purwo Nugroho said, as reported by The Jakarta Post.
"The sulfuric gases emanating from the fracture are also denser than before,” he said yesterday, adding that the drone's photos also revealed a small fracture in the southeastern part of the crater.

Mount Agung seismic energy continues to decline. The highest energy was 22-9-2017, when raised to Alert 4. After that it was downhill. pic.twitter.com/zdaPDSm0Ui— Sutopo Purwo Nugroho (@Sutopo_BNPB) October 16, 2017

While seismic activity under Agung is still increased, the seismic energy continues to decline. "The highest energy was on September 22, 2017, when the status was raised to 4. After that it was downhill," Nugroho said.
On numerous occasions, Nugroho urged people to stop spreading fake news, adding Bali is safe four tourists.
Mount Agung is located on the east side of Bali. The volcano is about 70 km (43 miles) from the main tourist areas of Kuta and Seminyak, which remain unaffected for now.

Symmetrical Agung stratovolcano, Bali's highest and most sacred mountain, towers over the eastern end of the island. The volcano, whose name means " Paramount," rises above the SE caldera rim of neighboring Batur volcano, and the northern and southern flanks of Agung extend to the coast.
The 3142-m-high (10 308 feet) summit contains a steep-walled, 500-m-wide (1 640 feet), 200-m-deep (656 feet) crater. The flank cone Pawon is located low on the SE side.
Only a few eruptions dating back to the early 19th century have been recorded in historical time. The 1963-64 eruption, one of the world's largest of the 20th century, produced voluminous ashfall along with devastating pyroclastic flows and lahars that caused extensive damage and many fatalities.
