Earth Tremor in the Remote Southern Waters A powerful earthquake struck late on Thursday night in the remote waters of the Drake Passage, a stretch of ocean that lies between the southern tip of South America and the northern edge of Antarctica.

The epicenter of the 7.5-magnitude quake was in the Drake Passage, a body of water between the southernmost tip of South America and Antarctica.
