Picture 1: Location of the magnitude 5.2 earthquake in New Britain Region, P.N.G.

The earthquake occurred in an area where we announced MODERATE and INCREASED seismic hazard exposure (blue and yellow alert) in our latest weekly earthquake forecast for the Indonesia region, on May 13, 2024, available here.

The earthquake also occurred due to the rotational singularity (marked with white) that is present in Papua New Guinea region. We posted about it on May 7, 2024, and is accessible here.

Rotational singularity can occur when the fault planes are "infinitely" close to each other or the theoretically infinite shear- and normal tractions are associated with finite (micro)rotations within infinitely small regions (volumes of rocks). In practice, this happens when tectonic waves with low Cosserat lengths (generally) interact with each other within a region. Its shape can be elongated (like e.g. before the Great Noto Earthquake in Japan) or circular.

There have been no reports of damage, injuries, or casualties as a result of the earthquake so far and no particular alert was issued.

 

* The exact information about the magnitude, epicenter, and depth of the earthquake might be revised within the next few hours as seismologists review data and refine their calculations, or as other data providers issue their reports.
