The 1815 Bali earthquake occurred on November 22 between 22:00 and 23:00 local time (WITA), affecting the Bali Kingdom. The estimated surface wave magnitude 7.0 earthquake struck off the north coast of Bali at a shallow depth. It was assigned a maximum intensity of IX (Violent) on the Mercalli intensity scale, causing severe damage in Buleleng and Tabanan. Mountains at the coast experienced landslides and mudflows, killing 10,253.[2] A destructive tsunami washed onto the Balinese coast, killing another 1,200 people.[3][4]
The earthquake and tsunami is thought to be the result of a thrust fault rupture on the Flores Back Arc Thrust Fault.[5] The fault formed due to the convergence between the Sunda and Australian plates, accommodating compression. The two plates converge at a rate of 80 mm/yr, in which the Sunda megathrust takes 70 mm/yr of the movement. The remaining 10 mm/yr rate is accommodated by the Flores Back Arc Thrust Fault. It runs off the north coast of the Lesser Sunda Islands, in the Banda Sea.[6]
