A massive, magnitude-7.2 earthquake rocked the South Sandwich Islands, an uninhabited British territory off the coast of Argentina in the southern Atlantic Ocean, on Monday.
It posed no tsunami danger to any part of North America, but the National Oceanic and Atmospheric Administration said in a statement that “earthquakes of this size are known to generate tsunamis dangerous to shorelines near the source.”
The U.S. federal agency said the 19-mile-deep quake struck at 10:04 a.m. EDT, off the southeastern coast of Bristol Island.
It is unclear whether the quake caused any damage to nearby islands.
