Awesome, thank you. Could someone also provide a little synopsis of the last week? How it was figured out, what's happening, what could happen? I know it's all in those links but it would save a lot of people a lot of time.

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.
The dilatational deformations that we detected are very important for hazard mitigation efforts in volcanic fields because such deformations may eventually cause hydrothermal explosions that are considered to be a serious volcanic hazard.
Study by Robert Smith - QUAKE IN ALASKA CHANGED YELLOWSTONE GEYSERS From 2,000 Miles away.
A powerful earthquake that rocked Alaska in 2002 not only triggered small earthquakes almost 2,000 miles away at Wyoming's Yellowstone National Park - as was reported at the time - but also changed the timing and behavior of some of Yellowstone's geysers and hot springs, a new study says.
While other large quakes have been known to alter the activity of nearby geysers and hot springs, the Denali fault earthquake of Nov. 3, 2002, is the first known to have changed the behavior of such hydrothermal features at great distances, according to Smith and his colleagues. They say the magnitude-7.9 quake was one of the strongest of its type in North America in the past 150 years.
Scientists once believed that an earthquake at one location could not trigger earthquakes at distant sites. That belief was shattered in 1992 when the magnitude-7.3 Landers earthquake in California's Mojave Desert triggered a swarm of quakes more than 800 miles away at Yellowstone, as well as other temblors near Mammoth Lakes, Calif., and Yucca Mountain, Nev.
For all those interested in a very well respected and silenced by the USGS Geologist Jim Berkland discussing the recent swarm on the 6th Jan 09:
Here is the Coast to Coast 1 hour interview about the swarm at Yellowstone,
It is an MP3 Download format, and not uploaded by myself but by a C2C archivist, full commercials please do listen to them.
