Picture 1: Location of the magnitude 5.4 earthquake in Mindanao, Philippines.

The earthquake occurred in an area where we highlighted that the rotational singularity will contribute to the INCREASED seismic hazard exposure, as shown here and in the picture below.

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.

The earthquake also occurred in an area where we announced HIGH seismic hazard exposure (orange alert) in our latest weekly earthquake forecast for the Indonesia region, on February 26, 2024, available here.

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