Did you feel shaking in Yukon at 1:41 p.m. MST today? That was a M7 #earthquake near the seismically active YK-AK border and 250 km to the west of #Whitehorse.
Shaking was felt across much of Yukon and southeastern AK.

There was an earthquake alert that went out this morning for a M5.9 near Reno, NV. This was a false alarm. There was no earthquake.
The USGS is working to identify the issue.
More soon.
