How active is the activities fair?

The geology department set up a seismograph. It was neat. When we jumped near the sensors, we could see the needle waver in response.This post's theme word: pluton, "an intrusive rock, as distinguished from the preexisting country rock that surrounds it."

Re the title: pretty active, but only recently. N.B. the lack of noise in the early passes of the seismograph.
