The Scotia subduction zone is an interesting oceanic subduction zone that is possibly related tot he opening between South America and Antarctica. Today&#8217;s earthquake occurred in a fault system that involves both transform faults and oceanic spreading ridges. In the region of this earthquake, this system is mapped as a transform fault (&#8220;strike-slip,&#8221; similar to the San Andreas fault).<br \/>\nThe moment tensor, which tells us about the type of earthquake that slipped (eg. strike slip, reverse\/thrust, or normal), shows this earthquake to be primarily strike-slip. Based on the mapped plate boundary fault here, I would interpret this to be a left-lateral strike-slip earthquake.<br \/>\n<a href=\"http:\/\/earthjay.com\/earthquakes\/20131116_M68_scotia\/20131116_M68_scotia_moment_tensor_Mww.JPG\" target=\"new\" rel=\"noopener\"><img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20131116_M68_scotia\/20131116_M68_scotia_moment_tensor_Mww.JPG\" alt=\"global\"\/><\/a><br \/>\nHere is the <a href=\"http:\/\/earthquake.usgs.gov\/earthquakes\/eventpage\/usb000kznc#summary\" target=\"new\" rel=\"noopener\">USGS<\/a> page.<br \/>\nHere is a map of this part of the southern hemisphere:<br \/>\n<a href=\"http:\/\/earthjay.com\/earthquakes\/20131116_M68_scotia\/20131116_M68_scotia_map_global.JPG\" target=\"new\" rel=\"noopener\"><img decoding=\"async\" src=\"http:\/\/earthjay.com\/earthquakes\/20131116_M68_scotia\/20131116_M68_scotia_map_global.JPG\" alt=\"global\" width=\"100%\"\/><\/a><br \/>\nHere is a map of the tectonics of the region.
