Comrie: a historical scottish earthquake swarm and its place in the history of seismology

Earthquake swarm activity at Comrie, Perthshire was particularly marked in the period 1839–1846. It served as a focus for early scientific interest in earthquakes in the UK, chiefly under the aegis of the British Association for the Advancement of Science. The work done included both macroseismic and instrumental investigations, and saw the first use of the inverted pendulum in seismology, as well as the first seismometer network anywhere in the world.
