Update (4-29-11, 12n, EDT): Nick Tew reports power and internet has been restored to the Survey. He also passed along this update:
We have some of our folks who have severely damaged homes, but all are ok, physically. There are parts of Tuscaloosa that have been utterly devastated and whole neighborhoods have been wiped off the map. A major commercial area was destroyed, but downtown and the University are ok. We won’t know the total death toll for some time to come, but it’s bad. Many, many are homeless and have nothing left.
