Bali is located in a seismically active zone and faces moderate to high earthquake and tsunami risk. The island sits near the Sunda Arc subduction zone, where the Indo-Australian Plate slides beneath the Eurasian Plate.
Earthquake Risk
Bali experiences regular seismic activity. The 2018 Lombok earthquakes (M6.9) caused significant damage in neighboring islands and were felt strongly in Bali. Historical records show multiple destructive earthquakes affecting the island.
Tsunami Risk
The southern coast of Bali faces tsunami risk from earthquakes along the Java Trench. While major tsunami events have been rare in Bali specifically, the 2004 Indian Ocean tsunami and 2018 Sunda Strait tsunami demonstrate the regional threat.
Volcanic Risk
Mount Agung, Bali's highest peak, erupted most recently in 2017-2019. It remains an active volcano that could produce eruptions, lahars, and ashfall affecting large portions of the island.
