The United States Geological Survey reports a preliminary magnitude 6.8 earthquake struck near Kasiguncu, Indonesia today. There was no initial word on damage or injury resulting from the quake.
Kasiguncu is an urban village in Poso Pesisir , Poso , Central Sulawesi , Indonesia.
There have been 22 M7.5+ earthquakes recorded in the New Guinea region since 1900. The dominant earthquake mechanisms are thrust and strike slip, associated with the arc-continent collision and the relative motions between numerous local microplates.
The largest earthquake in the region was a M8.2 shallow thrust fault event in the northern Papua province of Indonesia that killed 166 people in 1996.
The western portion of the northern Australia plate boundary extends approximately 4800 km from New Guinea to Sumatra and primarily separates Australia from the Eurasia plate, including the Sunda block. This portion is dominantly convergent and includes subduction at the Sunda (Java) trench, and a young arc-continent collision.
