Geological records show Yellowstone’s most recent period of activity – lava flows – ocurred about 70,000 years ago.
And the volcano’s three biggest eruptions went off about 640,000, 1.3 million and 2.1 million years ago.
Although the USGS has assured this is not the case, the cycle of eruptions has led many to believe Yellowstone erupts like clockwork and that we are overdue for another blast.
But even if Yellowstone is not overdue and is not expected to erupt any time soon, could the Idaho seismicity 155 miles away have any impact on the volcano’s odds of blowing?
According to the USGS, the simple answer is: “No.”
