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

A new study finds large earthquakes can cause ice on the slopes of Antarctica's Mt. Erebus to quiver and vibrate, even when the quake happens thousands of miles away. These icequakes, as they're called, aren't large enough to cause any harm but humans can hear them when they cause the ice to crack and pop. "Large earthquakes that are a thousand miles away from Mt. Erebus can affect the seismic activity here," said Chenyu Li, a Ph.D. geophysics student in the School of Earth and Atmospheric Sciences, and lead author of the new study. "The higher the magnitude, the further away it can be felt."
