How seismometers record church bells ringing

A new study made by Jordi Díaz, researcher at Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC), has compared the different types of bell ringing to indicate the passage of time used in several European countries using recordings of seismometers installed near bell towers. The study, which has been published recently in the Journal of Seismology, describes the characteristics of the seismic signal recorded by stations installed close to four churches from Greece, France, Italy and Spain. The work reflects the existing differences in traditions still active in Europe to mark the hours with bell ringing.
