The Carlsberg Ridge is associated with earthquakes because it functions as a divergent plate boundary, a location where tectonic plates move apart.12
According to the theory of plate tectonics, new lithosphere is continuously created at such oceanic ridges through the upwelling and cooling of magma from the Earth's mantle. This dynamic geological process generates significant seismic activity, and the Carlsberg Ridge specifically coincides with a major belt of seismicity in the Indian Ocean. Additionally, earthquakes in these regions can be linked to strike-slip faults, known as transform faults, which offset the ridge crests and accommodate the horizontal motion of the plates.213
