We obtain a large dataset of seismic data from the temporary seismic network AlpArray in Europe and a large dataset of lightning data from the lightning location system Austrian Lightning Detection and Information System and focus on the investigation of thunder signals recorded with seismic stations in a frequency range of 10-49 Hz if no other frequency band is specified. We try to establish whether important infor-mation about a lightning flash can be determined independent of optical and electrical measurements through the means of seismic analysis. Seismic data provide useful infor-mation on thunder and lightning, and we observe a correlation between lightning peak current and maximum ground displacement induced by the thunder for positive cloud-to-ground flashes of lightning.
