In Canada's Yukon Territory, about 8,000 people lost power for a short time, while damage was reported to a handful of buildings.
A little after 6 a.m., Revenaugh felt the second quake, which was a little bigger than the first at an about 6.3 magnitude quake.
The initial large quake hit around 4:30 a.m.
The quake was followed by multiple aftershocks Monday morning, including a quake that the USGS says was even larger.
Earthquakes of that size could cause "considerable damage in poorly built or badly designed structures", according to the USGS.
Four hours after the quake, the geological survey had recorded more than 50 temblors, and aftershocks continued to shake the area.

The shaking roused state Rep. Scott Kawasaki, who spent the night at his Capitol office in Juneau.
He said he was reminded of the recent renovation of the Capitol, meant to fortify it against earthquakes.
She said she had spoken to police in the town of Haines about 30 miles south and they also had not gotten reports of injuries or damage from the first quake.
It was centred in a remote area 77 kilometres northwest of Skagway, Alaska, and 127 kilometres southwest of Whitehorse. However, preliminary data indicates the faults were not involved, according to the Alaska Earthquake Center.
Stanford said the quake knocked pictures off the walls and glasses off shelves, but there wasn't any structural damage to his home.
