See: https://earthquake.usgs.gov/earthquakes/map/?currentFeatureId=us6000f4mr&extent=-66.96448,-406.58203&extent=-48.40003,-364.39453&listOnlyShown=true&baseLayer=terrain
I scan the USGS earthquake page each day a part of my weather review and in the years I've been observing, never seen a swarm this powerful and sustained. Would not want to be existing in that area and shudder to think what this would do in a highly populated zone.

From Wikipedia:
No permanent native population lives in the South Sandwich Islands, and a very small non-permanent population resides on South Georgia. There are no scheduled passenger flights or ferries to or from the territory, although visits by cruise liners to South Georgia are increasingly popular, with several thousand visitors each summer.
Data (scroll down to see the big one at 7.5 magnitude):
67 of 117 earthquakes in map area.

(3,622 posts)Good thing that's not a populated area.

(47,565 posts)Ive lived in Southern California almost 60 years and Ive never heard of an earthquake storm.

(9,111 posts)Don't typically see so many 5.0+ like that.
That whole area is a tectonic mess, though. The Scotia plate is getting it from all sides.
