Context by seismologist Dr. Lucy Jones:
Idaho has a history of bigger quakes. In 1983, the Borah Peak quake was M7.0. Today's quake is almost 100 miles northwest of the 1983 event.

Idaho is part of the Basin and Range tectonic province. Everything west of the Wasatch Mtns. is getting slowly stretched out as a bit of North America tries to cling to thePacific plate

A technical explanation:
USGS focal mechanism for M6.5 Idaho earthquake indicates strike-slip faulting, but has a large non double couple component (50%), so this might be a complex event. Borah Peak sequence to the East was normal faulting. https://t.co/wbFnmG2BKX pic.twitter.com/zaDLJosd4m

New York Times reporter Mike Baker reported no damage has been reported so far.
Some good news: No reports of damage from any of the people I've talked to, including a commissioner in Challis and an emergency responder in Idaho City who said they went to check 19th-century buildings with unreinforced brick.
But shaking reports in ID, WA, MT, OR, UT, NV, AB https://t.co/ZNvWX5mhrj
