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 8 m to 10 m, which soon traveled onto Sulawesi. The most extensive waves reached 300 m inland, destroying 700 homes and killing around 200 people.

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

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