An official says Nepal's earthquake was picked up as far away as Antarctica and Argentina by seismic stations that monitor the globe for underground nuclear testing.

The executive secretary of the Comprehensive Nuclear-Test-Ban Treaty Organization told reporters Tuesday that 70 stations in all detected Saturday's magnitude-7.8 earthquake.

Lassina Zerbo says the monitoring stations can pick up the effects of an earthquake, but they are not able to predict one.

Zerbo spoke on the sidelines of a United Natinos gathering of world powers to discuss progress toward a world free of nuclear weapons.
