Pyhäsalmi Mine Microseismic Waveform Dataset — Raw MiniSEED and Station Metadata (Oct 2010–Apr 2011)

This dataset contains raw microseismic waveform recordings and associated station metadata from the underground Pyhäsalmi copper-zinc mine (Finland), covering the period October 2010 to April 2011. Data were originally sourced from the EPISODES Platform (episodesplatform.eu, Institute of Geophysics, Polish Academy of Sciences / IS-EPOS), episode PYHASALMI_MINE. The archive includes: Individual seismic events in MiniSEED format, recorded by a mixed 1-component/3-component underground geophone network (sampling rate: 6000 Hz). A StationXML file describing network geometry (station coordinates, elevation, and channel epochs) for the same time window. This dataset is being used to develop and benchmark phase-picking, event location, and passive seismic tomography algorithms for mining-induced microseismicity
