A shallow earthquake with a preliminary 5.9 magnitude rattled the coast of Southeast Alaska early Friday morning, according to the U.S. Geological Survey.
The quake struck at 2:54 a.m. and was recorded at a depth of 6 miles. It was centered 50 miles west of Gustavus and 98 miles west of Juneau. The timing and size of the quake was nearly identical to one that struck the U.S.-Canada border on June 4.
A series of aftershocks followed, the largest of which was a 4.7 magnitude quake, which hit at 3:19 a.m., according to USGS.
There were no immediate reports of damage, but light shaking was reported around Juneau, according to USGS, and the quake disrupted Internet connections in the area, several sources reported. Numerous residents across the U.S.-Canada border in Whitehorse, Yukon, took to Twitter to report being awoken by the temblor.
