About 21 minutes after the 7.8-magnitude earthquake shook Nepal on April 25, waves of energy penetrated the Earth’s upper atmosphere creating a disturbance, NASA discovered.
This observation could bring scientists closer to one day developing a system to predict earthquakes and other devastating natural disasters.
More specifically, the emitted energy disturbed electrons in the ionosphere—the layer of atmosphere located 37 to 621 miles (60–1,000 km) above the Earth’s surface—according to readings taken from a GPS station in Lhasa, Tibet, some 400 miles from the quake’s epicenter.
