Registering a moment magnitude of 6.7, it killed more than 300 people, damaging structures and buildings across the Irian Jaya province.

Indonesia is highly active in terms of seismicity and volcanic eruptions, with a subduction zone and many faults.

Indonesia, one of the most seismically active places in the world, hosts hundreds of islands, many with volcanoes.

Unlike most subduction zones, the Sunda Trench is parallel to the chain of islands to which it corresponds, creating strike-slip faulting.

Earthquakes along the subduction zone at Sunda and on the Great Sumatran fault pose a serious threat to life, especially in the form of tsunamis.
