Sorong fault also (Sorong Fault Zone, SFZ) is an active, broad zone of inferred
earthquakes. It is one of the two major faults created by the Australian and Pacific plate convergence, the other being the Ramu-Markham Fault zone. The fault triggered the destructive 1998 North Maluku earthquake which killed 41 people.[1]
Location
The Sorong fault begins around Sulawesi and runs towards New Guinea. It marks the boundary between Halmahera plate and Bird's Head Plate. The Sorong fault system has been documented to extend westward more than 500 miles (800 km) from Teluk Sarera to Kepulauan Banggai.
Geology
The fault zone juxtaposes
ophiolitic
rocks.
Plate evolution
It is widely believed that fragments of the northern Australian continental margin in
Bacan, Obi Islands, and Sula Islands
), suggest a less mobilist interpretation of the region than previous reconstructions. SFZ did not begin to develop in its present form before the late Miocene.
