Lightning is a common meteorological phenomenon, and during thunderstorms numerous lightning strikes also influence seismic records worldwide. This can be due to electrical induction in the coils of a seismometer, electric fields influencing analog digital converters or other electronic components, or ground motions induced by the lightning strike itself and/or the acoustic coupling of the accompanying thunder. Most experimental seismologists have experienced the problems of strong electrical currents during lightning events damaging recording equipment or causing false triggers or alarms, a common problem in central Europe during the summer (i.e., Cranswick et al. 1985; Taylor et al....
