The '''1674 Ambon earthquake''' occurred on February 17 at between 19:30 and 20:00 local time somewhere in the Maluku Islands. The resulting tsunami reached heights of up to 100 meters at Ambon Island killing over 2,000 individuals. It was the first detailed documentation of a tsunami in Indonesia and one of the worst tsunamis in the country. |

The 1674 Ambon earthquake occurred on February 17 at between 19:30 and 20:00 local time somewhere in the Maluku Islands. The resulting tsunami reached heights of up to 100 meters at Ambon Island killing over 2,000 individuals. It was the first detailed documentation of a tsunami in Indonesia and one of the worst tsunamis in the country.
Tectonic setting
The tectonics of the North Maluku Islands is dominated by complex collision, subduction and strike-slip elements. Intermediate to deep focus earthquakes with focal depth of 60 km or greater is immediately ruled out as the souce because no known historical events of the same kind has generated a large tsunami. The 1938 Banda Sea earthquake, an intermediate depth magnitude 8.5 event only caused a minor tsunami.
The Seram Trough is a zone of complex convergence between the Pacific, Australian, Sunda and numerous micro tectonic plates. This megathrust fault is located north of Seram Island. While it has generated large tsunamigenic earthquakes in the past such as that in 1899 and 1629, the fault is situated too far from Ambon to have caused huge tsunami run-ups.
