A magnitude 6.7 earthquake hit Guam on Tuesday, resulting in the loss of power on the island but not much other damage, according to a report from USA Today.

The earthquake was initially reported to be a magnitude 7.1, but was later reduced. The epicenter of the quake was 28 miles northwest of Piti Village on Guam's coast and was 85 miles deep.

"By all accounts, Guam was not affected in a major way by this strong earthquake," according to a news release from the U.S. Department of Homeland Security's Joint Information Center on Guam. The report also said that there were no injuries and no damage to roads or bridges. The quake did cause a landslide in East Agana, near the capital of Hagatna.

Guam is a U.S. island territory about 4,000 miles west of Hawaii and 1,600 miles southeast of Japan.

Guam's earthquake, which struck at 4:15 p.m. local time -- 2:15 a.m. Wednesday, ET -- was seven times more powerful than the magnitude 6.0 quake that hit Napa Valley, California on Aug. 24.

That temblor killed one and injured 120, and caused upheaval in Napa's winemaking region, potential costing more than $1 billion in damages. It was the strongest earthquake to hit northern California's Bay Area in 25 years.

California's earthquake likely caused so much more damage because the epicenter was only seven miles deep, much shallower than Guam's quake.

"Everything and everyone in Napa was affected by the quake," CNN reporter Malissa Koven said at the time. "My house, along with everybody else's, is a disaster. It looks like somebody broke in and ravaged the place, room by room. Anything and everything that could fall, did."

Guam officials said that the quake's depth of 85 miles prevented it from causing any major damage to buildings, roads or bridges.
