There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

There are two supervolcanos within the U.S., the most famous one underneath Yellowstone National Park. If any of these erupt, all that ash and dust in the atmosphere could be catastrophic for Earth's climate. Fortunately, supervolcano eruptions are few and far between, which is why scientists are trying to learn as much as they can now about why they're so rare. A new study published in Nature Geoscience by a team including School of Earth and Atmospheric Sciences professor Josef Dufek theorizes that supervolcanos rely on very deep magma reservoirs that can take millions of years to form.
