The unusual and concerning quake reports out of Yellowstone has everyone looking at seismographs until their eyes bug out. The unusually long and pointed earthquake swarm occurring since Dec. 26th has transformed into harmonic tremors, which the red circle depicts.
"It has been reported and noted by the USGS that an earthquake swarm has been occurring under Lake Yellowstone since December 26th. The attached webcorder display shows that after the tremor swarm activity died down this evening a new pattern of potential classic harmonic tremors has started and continues at the time of this posting. Harmonic tremors could mean lava is now moving under the Yellowstone super volcano."
"The USGS has made no updates since these tremors began."

"There have been more earthquakes than usual centered under the ancient Yellowstone Supervolcano's Caldera and the small quakes are enough that that has scientists concerned about a huge eruption from Yellowstone. Researchers are stumped as to why the earthquakes are stronger than usual."
"A report from Gene Byrd notes, "The park has thousands of earthquakes each year but these have researchers concerned and the report notes that they have long predicted that the Yellowstone supervolcano will eventually erupt again."
There is always a lot of seismic activity in and around the Yellowstone caldera. What is different this time are the length of the swarm, the absence of the tremors relating to a known fault, the fact that it is under the lakebed, the rising ground where the alleged magma bulge is, and they are extremely shallow. The BBC produced a series called "End Day", showing in movie form a la Ground Hog day, the same man awakening to the last day on earth, each time the earth ends differently. The six most likely scenarios are the backdrop, and one of these likeliest are the Yellowstone Supervolcano eruption. The clip intersperses scientific information in between the storylines. It's 9 min. I don't think Yellowstone Supervolcano is going to erupt yet, but what do I know. It has caught the interest and attention of scientists worldwide, though.
