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.
Seismologists Chris Bean & Martin Möllhoff from the Dublin Institute for Advanced Studies (DIAS) addressed a large audience 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 were 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?
Now in its fifth year, Samhain agus Science brings together researchers from DIAS and around the world for a series of free in-person and online events that take inspiration from the Celtic festival of Samhain and look at the dark side of science.
The festival aims to make the big scientific questions of our time and Celtic history relevant, accessible, and fun to a general audience who might not normally be familiar with these topics.
