Since December 27th more than 500 quakes have struck under Yellowstone Lake, which is mostly situated within the Yellowstone Caldera. This caldera formed when Yellowstone's enormous volcano collapsed in on itself after the last eruption 640,000 years ago.
While Yellowstone Lake covers an impressive 136 square miles, it is nothing compare to the massive caldera that measures 53 miles across at its widest. Under this massive caldera swirls a giant magma chamber about 6 miles beneath the surface.
For a really good overview of Yellowstone's layout, check this map.
Yellowstone sees periodic ground heating – sometimes so much so that parts of the park close like it did in 2003. The site of a magma bulge under the Lake is where these 400 quakes have hit.
The sharpest portion of the bulge began to expand in 1995 and in 1999 it measured roughly 2000 feet long and rose some 100 feet. However the uplift area encompasses virtually the entire caldera as shown in the satellite interferogram (below left). The bulge, about 25 miles across, rose 5 inches from 1997 to 2003. Despite these features, the caldera – thankfully – refuses to erupt.
This is good because the last two eruptions encompassed two-thirds of the continental US. Much of America would be in a world of hurt, if not "toes up". So would the rest of the globe just by virtue of the traveling ash cloud. Global dimming, massive cooling and a "nuclear winter" would be a certainty. By comparison, the Mount St. Helens' 1980 eruption was smaller than a bump on a pickle and Helen's ash cloud circled the world twice in two weeks.

Image: This interferogram provides a map view of ground movements at Yellowstone. Each color contour represents a line of equal uplift relative to the ENVISAT satellite between Sept. 2004 and Aug. 2006. The center of the uplift is an elliptical region stretching from the northeastern part of the Yellowstone Caldera (the dashed black line) to the southwest. This area of maximum uplift encompasses both Yellowstone's resurgent domes, features long known for similar movements. During this time period, the north-rim uplift anomaly subsided (bullseye in the upper left part of the interferogram). The yellow lines are roads. The yellow triangles are locations of GPS stations with continuous data. The light blue lake within the caldera is Yellowstone Lake. Thin black lines are mapped faults. (C. Wicks, USGS)
YELLOWSTONE'S FAULTS

You can see from this map that numerous earthquake faults surround the lake, but only one enters the water to any significant degree. This is especially interesting when you look at this Google Earth map, which shows a better view of the recent quake activity. You can click here, for a larger view. The area shown in this image corresponds to the pink circle in the top USGS map.
WHAT DO ALL OF THESE QUAKES MEAN?
Probably nothing. Yellowstone's swarms go in fits and spurts – much like breathing in and out. All is well as long as she doesn't go into a coughing fit! However, it behooves us to keep an eye on this activity.
YELLOWSTONE RECENT QUAKES
Notice the very shallow depth of these events. It's likely, due to the near-surface location, that out-gassing could be detected or some bubbling on the lake.
