A moderately strong eruption took place at Mount Agung, Bali, Indonesia at 01:05 UTC (09:05 local time) on July 15, 2018. Ash column rose up to 5.2 km (17 000 feet) above sea level, according to Darwin VAAC. The eruption lasted 1 minute and 45 seconds.
"The ash cloud is observed as a thick intense cloud that tends to face the southeast region and west," said Sutopo Purwo Nugroho, spokesperson for the National Disaster Mitigation Agency (BNPB).
The event was preceded by a smaller but longer (2 minutes and 20 seconds) eruption at 20:52 UTC on July 14.
Ashfall was reported in nearby villages and communities.

According to Sutopo, Agung's status remains at level 3 ‘siaga.’
BNPB recommends people not to conduct any activities in the region considered to be within the danger zone, which includes hiking. The danger zone is 4 km (2.5 miles) around the crater.
While flights in and from Bali can sometimes be affected, today's eruption had no impact on the tourism industry and airports are secure and operating normally. This volcano is far away from tourist destinations.
Seismic activity is characterized by low frequency earthquakes.
Sulfur dioxide flux was 1 400 - 2 400 tons/day on July 3 and 400 - 1 500 tons/day on July 4. Satellite data acquired on July 4 indicated continuing lava effusion in the crater, with 4-5 million cubic meters effused in the past week.
