Bali volcano

After the last eruption in 1963, Bali volcano Mount Agung is threatened to erupt again.




The increasing number of earthquakes occurring around Gunung Agung in eastern Bali, Indonesia, over the past few weeks.

The latest warnings issued by national and local government agencies prohibiting mountain climbing and instructing the evacuations within 12km from the summit.

The eruption of Mount Agung has become one of the global volcanic activities of the last 100 years. More than 1,000 people died in the last eruption in 1963.

Gunung Agung is one of the many similar volcanoes in Indonesia within the Ring of Fire that surrounds the Pacific and Indian eastern oceans.

Bali Volcano eruption 1963

Mount Agung is a large volcano with an altitude of 3,142 meters above sea level. This mountain dominates the east side of Bali.

The 1963 eruption was preceded by an earthquake. In February 1963, the lava started to flow from the top of the crater, which eventually reached about 7km down the northern slope. Small explosion of volcanic ash occurred because of this activity.

The intensity of explosive activity expanded rapidly toward a major explosion on March 17th. Simultaneously, the eruption of debris flow-embracing the terrain of hot red lava blocks, ash and gases destroyed the surrounding areas.

Heavy rain on fragmental volcanic material triggers mud flow and large rocks to the other side of the mountain. This debris flow is called lava, an Indonesian word that has been adopted globally. Another major explosion occurred two months later from Agung volcano with similar physical consequences.


The current situation of Bali Agung Volcano

Based on the activity of  the last eruption of Mount Agung in 1963, there is concern that the volcano may be experiencing a major eruption in the near future.

There was a similar intensity eruption in 1843, and some in the 16th to 18th centuries.

The accurate eruption can only be predicted within periods of time and hours, similar to what happened with Mount Pinatubo in the Philippines in 1990, that saved many lives.

It is not easy to relocate the people to stay away from the natural hazards. But Indonesia is the most volcanically active country on Earth, and has become an expert in protecting the civilian population living around the volcano areas.

The related authorities are now intensely and closely monitoring the activities of Bali Agung volcano.

It is crucially important to follow the advice of related expert authority in order to avoid the potential danger caused by the Bali Volcano.
