Picture 1: Location of the magnitude 5.4 earthquake in New Ireland Region, P.N.G.

The earthquake occurred due to the rotational singularity (marked with a black ellipse)  present along New Ireland Region, P.N.G. 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.
