A strong offshore earthquake has just hit south of Panama and Costa Rica.

The U.S. Geological Survey measured it as a 6.8-magnitude that struck at 4:15 p.m. Panama City time (2:15 p.m. Vancouver time) today (July 21) at a depth of 10 kilometres (six miles).

The epicentre was located 49 kilometres (30 miles) south of Punta de Burica, Panama; 76 kilometres (47 miles) south of Puerto Armuelles, Panama; and 106 kilometres (66 miles) southwest of La Concepción, Panama.

The U.S. Tsunami Warning System, which listed it as a 7.0-magnitude quake, stated that there isn't a tsunami danger from this earthquake to the North American West Coast, including B.C. 

This earthquake follows seismic activity on July 17 in the same area, which included a 6.1-magnitude quake, followed by a 4.2-magnitude temblor.
