The 1968 Sulawesi earthquake struck Indonesia on August 14. It had a Richter magnitude of 7.4, spawned a large tsunami, and killed roughly 200 people.

Damage and casualties

The earthquake had a Richter magnitude of 7.4. It created a tsunami with wave heights of 8m (26feet) to 10m (30feet), which soon traveled onto Sulawesi. The most extensive waves reached 300m (1,000feet) inland, destroying 700 homes and killing around 200 people.[1]

Geology

The earthquake ruptured along Palu-Koro fault[2] in Manimbaja Bay. It caused subsidence that decreased elevations by as much as 2m (07feet) to 3m (10feet) along the coast. It also appeared to uplift at least one of the Togian Islands.[1]

The earthquake was near the Celebes Sea; it sank the island of Tuguan.
