My daughter posted on F.B. and she called out as fake, a Yellowstone Geyser, with molten lava
spitting out. Some of this click bait B.S. isn't helping us determine what the real quakes are doing in N.W. Montana. My son was still up in
Lewiston, Idaho, on the Wash. State border, and he felt the sofa under him start to "buzz". Some photo frames hanging on his wall, also started
banging back and forth.
Lewiston is pretty much West of Missoula, Mt. and the 5.8 quake is pretty much East of Missoula. So this shaker propagated pretty far to the West,
from it's epicenter. Lewiston is still on top of the massive granites of the North American Plate. Not too far to the West, in Washington State,
the Granite breaks away to Lord knows what. There's a mile deep puddle of solidified basalt members, on top of the basement rocks.
Haystack Rock on the Oregon coastline, flowed from the Kamiah Basalts off to the East of Lewiston. At that time in Geologic History, ( Miocene ),
things were extremely flat, all the way to the Pacific Ocean. The Cascades weren't even beginning to uplift, then.
This latest quake was only part of the continental divide's normal creaking. I doubt that it's connected to the Yellowstone Plateau, except that near
Craig Pass, the Continental Divide runs through, near here.
