Even though we cannot feel it, the ground is always trembling beneath our feet. We know this because really sensitive earthquake detectors feel these vibrations. Join seismologists Chris Bean & Martin Möllhoff from the Dublin Institute for Advanced Studies (DIAS) underground in Mitchelstown Cave, where a new seismic station records vibrations in the underworld, even when there is nobody around. Audible versions of seismic data will be played back inside the cave to demonstrate different types of ground motions. How does the cave vibrate when seismic waves originating from a very large distant earthquake pass? How do smaller local earthquakes compare? And what other types of signals are detected by the seismic station in the cave? Is the seismic station listening to you too?

This talk is part of the annual DIAS Samhain agus Science public lecture series. For more events, please see our website: dias.ie.
