Mount Agung or Gunung Agung is a volcano in Bali in Indonesia, located south east of Mt Batur volcano, also in Bali. Gunung Agung stratovolcano is the highest point on Bali. It dominates the surrounding area, influencing the climate, especially rainfall patterns.

Balinese believe that Mt Agung is a replica of Mt Meru, the central axis of the universe. One legend holds it that the mountain is a fragment of Meru brought to Bali by the first Hindus. The most important temple on Bali, Pura Besakih, is located high on the slopes of Gunung Agung.[4]

Gunung Agung last erupted in 1963–1964 in one of the largest and most devastating in Indonesia's history. It is still active with a large and very deep crater which occasionally belches smoke and ash. From a distance, the mountain appears to be perfectly conical.

From the peak of the mountain, it is possible to see the peak of Mt Rinjani on the nearby island of Lombok, to the east, although both mountains are frequently covered in clouds.


1963–64 eruptionEdit

The volcano last erupted in 1963 in one of the largest and most devastating in Indonesia's history.

On February 18, 1963, local residents heard loud explosions and saw clouds rising from the crater of Mount Agung. On February 24, lava began flowing down the northern slope of the mountain, eventually traveling 7 km in the next 20 days. On March 17, the volcano erupted (VEI 5), sending debris 8 to 10 km into the air and generating massive pyroclastic flows.[5] These flows devastated numerous villages, killing an estimated 1,100—1,500 people. Cold lahars caused by heavy rainfall after the eruption killed an additional 200. A second eruption on May 16 led to pyroclastic flows that killed another 200 inhabitants. Minor eruptions and flows followed and lasted almost a year.[6][7]

The lava flows missed, sometimes by mere yards, the Mother Temple of Besakih. The saving of the temple is regarded by Balinese as miraculous and a signal from the gods that they wished to demonstrate their power but not destroy the monument that the Balinese had erected.

Andesite was the dominant lava type with some samples mafic enough to be classified as basaltic andesite.[8]

2017 seismic activityEdit

In September 2017, an increase of seismic activity around the volcano raised the alert level to the highest level and about 122,500 people evacuated their houses around the volcano.[9] The Indonesian National Board for Disaster Management declared a 12-kilometer exclusion zone around the volcano on September 24.[10]

Evacuees have gathered in sports halls and other community buildings around Klungkung, Karangasem, Buleleng and other areas.[11] The monitoring station is located in Tembuku, Rendang, Karangasem Regency, where intensity and frequency of tremors are being monitored for signs of imminent eruption.[12]

The area experienced 844 volcanic earthquakes on September 25, and 300 to 400 earthquakes by midday on September 26. Seismologists has been alarmed at the force and frequency of the incidents as it has taken much less for similar volcanos to erupt.[6][13]


There are two main routes up the mountain; one from Pura Besakih proceeds to the higher western peak and starts at approximately 1,100 m (3,610 ft). The second route, reputed to take five hours (one-way), proceeds to the southern peak and commences higher from Pura Pasar Agung, near Selat.
