OK, we're a couple of days late on this, but what, you thought we weren't going to post it? Dudes, it's an implosion.
Cal State East Bay's Warren Hall was the most seismically vulnerable building in the California State University system. On Saturday, hundreds of spectators gathered to watch it get blown up real good after sitting empty for two years.
The spectacle lasted about 10 seconds as 430 pounds of explosives destroyed the 13-story building.
The implosion of Warren Hall mimicked the energy of a 2.0-2.5 magnitude earthquake, giving geologists a unique chance to study what happens below the surface. About 600 seismic sensors were installed within a 1.5-mile radius around the building. Read more on that in our earlier report.
