Eric Beyer was in his foreign language class at Van Hise Hall, one of the tallest buildings near the shore of Lake Mendota, when all of a sudden.
“Our entire class felt a lurch in the entire building,” Beyer says.
Seismologist Cliff Thurber says the tremor was due to an ice quake.
“It’s a big chunk of ice that thrusts upon himself,” Thurber says.
