Great analysis thanks. I saw the event on USGS and wondered about an event of its energy on what appeared on USGS to be the pre-trench portion of the plate. Now I get it. I have a question: is the Antarctic plate subduction passive in that without a spreading ridge South America’s Westward movement will slowly over ride it?
