M5.5 earthquake strikes Banda Sea
An earthquake of magnitude M5.5 struck the Banda Sea at 10:02 UTC on October 10, 2025. According to data provided by USGS, the event occurred at a depth of 158.2 km (98.3 miles).
The coordinates for the earthquake were 129.5°E and 6.9°S, placing the epicenter in the Banda Sea, a region surrounded by several islands of eastern Indonesia. The Banda Sea is known for its complex seismicity due to the interaction of the Australian and Eurasian tectonic plates.
Nearby infrastructure in this maritime region may include shipping routes, fishing grounds, and small island ports, as the area is not heavily urbanized.
There is no tsunami threat associated with this earthquake, based on its location and available data.
The significance index is 465 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
The Banda Sea region forms part of the complex tectonic boundary between the Australian Plate and local microplates, contributing to frequent seismic activity in the area.
