When did the 2018 Sulawesi earthquake and tsunami occur?

A magnitude 7.5 earthquake hit central Sulawesi, Indonesia, on 28 September 2018, triggering a tsunami and widespread liquefaction around Palu. The disaster killed thousands of people and caused catastrophic destruction in urban neighborhoods built on unstable ground. The event was especially important because it showed how earthquakes can generate multiple hazards at once, including tsunamis and ground failure. It also renewed attention on early-warning systems and coastal evacuation planning.
