Mama is always on the move! Movin’ and-a Shakin’!!! Earthquakes are happening all of the time, but it usually is the most temporally significant ones that receive the immediate attention. Well, the southern-most continent received a recent shaking at it’s edges this past weekend, as it apparently was large enough to attract outside attention.
This past Sunday, a magnitude 6.6 earthquake hit the outer edges of Antarctica. The epicenter of the quake actually was within The Southern Ocean, roughly 334 miles to the west of Coronation Island. This is the largest island of the South Orkney Island chain, which is located roughly 375 miles to the northeastern edge of The Antarctic Peninsula.
The seismic shift happened around 8:40 a.m., E.S.T.. The force of the quake was measured to extend roughly 6.2 miles into The Southern Ocean. The Pacific Tsunami Warning Center issued an initial warning, stating that their might be a small tsunami. However, a clearing was issued later, where any threats of major tidal impacts were dismissed. Warnings did remain about the possibililties of minor tsunamis that may have stricken the coasts of the continent, yet they were later dismissed by The Pacific Tsunami Warning Center.
This particular quake occurred at the adjoined locations of three tectonic plates. The Antarctic Plate, The Scotia Plate, and The South American Plate each shifted against each other’s borders, causing the tremor. It reached to a depth of 6.2 miles beneath the sea floor.
This tremor was followed by at least two aftershocks. A magnitude 6.2 aftershock stuck roughly 334 miles west of Coronation Island, forty minutes after the initial quake. A second discernable tremor happened two hours after that, measuring at a magnitude of 5.1. Things seem calm…. for the moment….

Totally off track, but since we are on the topic of shakin’…..
