A new satellite-based technique known as Interferometric Synthetic Aperture Radar (InSAR) allows direct and precise measurement of the vertical changes in ground level. This InSAR image of the area around the Yellowstone Caldera (dotted line) shows vertical changes during the 4-year period 1996–2000. The ringed pattern centered northwest of Yellowstone Lake is a prominent area of dome-shaped uplift. Each complete cycle of colors in the color bands represents a little more than one inch (28.3 mm) of vertical change. Yellow triangles are continuous GPS stations; white dots are locations of earthquakes in the period 1996–2000.

This afternoon and evening there has been 14 quakes at the park. While this may somewhat normal, I dont understand as to why all of these quakes are centered in Yellowstone Lake. Alot of red squares from USGS. Any seismic activity there raises red flags, but this seems to weird.

No super-volcano has gone off in recorded history.
