Several earthquakes struck Central Sulawesi province from 28–29 September. The strongest had a magnitude of 7.5 and triggered a tsunami that hit land at a speed of 800km per hour with waves of up to 6m. Land liquefaction caused by the earthquake also had serious humanitarian consequences as the fate of two villages with approximately 5,000 residents remains uncertain. At least 74,000 people have been displaced and 2,010 people have died, and these numbers continue to rise. At least 616,000 people have been affected.
