A meteor that exploded over Greenland this summer was so powerful that it shook the ground and was picked up by seismic sensors.

Residents in Qaanaaq, Greenland, reported seeing a bright light in the sky and feeling the earth shake around 8 p.m. local time on July 25.

The shaking of the ground was strong enough to set off seismographic equipment set up near the town, researchers said Wednesday at the annual conference of the American Geophysical Union, Live Science reported.

The meteor exploded with 2.1 kilotons of energy about 24 miles north of the U.S. Thule Air Force Base, according to the International Meteor Organization. Live Science reported it was the second most energetic explosion of its kind this year.

The Greenland fireball, as it came to be known, was at its brightest as it was traveling nearly 54,000 miles per hour (about 74 times the speed of sound) at an altitude of approximately 27 miles above Earth.

Seismic activity picked up by an array of seismic sensors set up by researchers with the Seismometer to Investigate Ice and Ocean Structure (SIIOS) at the University of Arizona correlated the path of the meteor with that of the traveling ground waves.

The array also enabled the researchers to pinpoint the exact location of impact near the Humboldt glacier on the Greenland ice sheet.

Tremors were picked up from as far away as 218 miles from the impact location on the ice sheet.
