Last night we rang the Wasburn bell, and by following our methods outlined in our proposal, we captured some seismic data from the structure during the ringing. The results were quite startling:
As seen in the graphic, some of the vibrations on the structure hit a bit more than 1G of acceleration. That is a significant amount of acceleration on a structure. Granted, the bell was supported by a wooden A frame resting on the floor, so it is likely it was allowed to move more than a normal bell tied into a vertical tower. But it was certainly something to see just how much force was present while a bell was ringing.
The raw data can be seen here.
