A strong Magnitude 5.8 earthquake has struck Montana, doing damage to buildings, roads, bridges and railroads and was felt over 100 miles in all directions!
The quake struck at 2:30 AM _Eastern_ US time and a very shallow depth of 4.3km – about 2 miles. It was the strongest earthquake in Montana in over 100 Years; and may be the strongest EVER in that state!
According to the US Geological Survey, the quake registered as a Level 7 on the Mercali Modified Shake Scale. This means the “perceived shaking” was “strong.” Here’s the Shake Scale from the USGS:
More concerning is that the earthquake actually registered on ALL 32 Seismographs at . . . Yellowstone National Park’s Super Volcano, 232 Miles away ! ! ! !
