A 6.3 magnitude earthquake struck the Pacific-Antarctic Ridge region today at the shallow depth of 1.1 km. The earthquake is the fourth earthquake to rattle the southern region of the globe in four consecutive days. On November 1, a 4.8 magnitude earthquake struck the Western Indian-Antarctica Ridge. On October 31, a 5.1 struck the tectonic plate conjunction of the Southeast East Pacific Rise and on October 30, the Southeast Indian Ridge was hit by a 4.5 magnitude earthquake.

Tectonic plate agitation has diffused across the planet over the last 45 days and we're seeing more unrest in places which typically don't have earthquakes like the 6.3 magnitude earthquake which struck Revilla Gigedo Island region west of Mexico on November 1. Whether this latest series of earthquakes shaking the southernmost hemisphere signals a major shift in planetary seismic stress or a further erosion of planetary magnetism remains to be seen. We will be watching developments very closely over the next few days.
