Earthquake stronger than Napa hits Guam, little damage

HAGÅTÑA, Guam — A 6.7 magnitude earthquake struck Wednesday off the northwest coast of Guam, causing power outages throughout the U.S. island territory but little damage.

The quake, which happened at about 2:15 a.m. ET, 4:15 p.m. local time, was about seven times stronger than the 6.0 magnitude tremor that hit Aug. 24 in Napa Valley, Calif. That earthquake injured 120 and killed one.

"By all accounts, Guam was not affected in a major way by this strong earthquake," according to a news release from the federal Department of Homeland Security's Joint Information Center on Guam. No injuries or damage to roads and bridges were reported although a landslide occurred in East Agaña, a suburb of the capital of Hagåtña.

No tsumani warning was issued for the earthquake whose epicenter was 28 miles northwest of Piti Village, Guam, at a depth of almost 85 miles. Initially, the quake was reported as having a 7.1 magnitude.
