The most popular posts to this blog are those concerning the potential eruption of the Yellowstone Super Volcano. Continuous activity of this massive caldera fascinates and causes concern for many. An eruption of the large, caldera forming size has happened at least three times in the past (see When Will Yellowstone Erupt?). This type of eruption, though not yet overdue, would cause climate changes as our civilization has never seen.
Below is an excerpt from the Yellowstone Volcano Observatory’s December, 27 2008 report:
The University of Utah Seismograph Stations reports that a swarm of small earthquakes of magnitude 3.5 and smaller is occurring beneath Yellowstone Lake in Yellowstone National Park, five to nine miles south-southeast of Fishing Bridge, Wyoming. The swarm began yesterday afternoon, Dec. 26, and has continued and intensified today. The two largest earthquakes in this swarm have been shocks of magnitude 3.5 and 3.4 which occurred at 1:17 and 1:26 pm MST, respectively, today. Many smaller earthquakes have also occurred, including three events this morning of magnitude 2.5 to 2.8 and a magnitude 3.2 event at 3:30 pm MST. Some of the earthquakes in the swarm have been reported felt by people in the Yellowstone Lake area. Swarms of this nature are relatively common in this part of Yellowstone Park.
Earthquakes in and around the Yellowstone area affirm the continuous underground activity. However, the likelihood of a major eruption is currently small. This should not deter visitors from visiting and enjoying the beauty of this great American national park.
