The United States Geological Survey recorded
a Magnitude 6.9 Earthquake at a depth of 35 km beneath western
New Britain slightly before 4.15 pm local time (slightly before 6.15 am
GMT) on Monday 17 October 2016. There are no reports of any casualties
associated with this event, but many people on the island are reporting
minor damage, and the event was felt on mainland Papua New Guinea.

New
Britain is located on the South Bismarck Plate, north of the Solomon
Sea Plate, which is being subducted beneath it. The plates do not pass
over one-another smoothly, but constantly stick together then break
apart as the pressure builds up, causing Earthquakes in the process.

accounts of Earthquakes can help geologists to understand these events,
and the structures that cause them. If you felt this event then you can report it to the Athens Institute of Geodynamics Here.
