Catalog of locations of microseismic events accompanying the 2006-2007 fluid injection into the Basel Enhanced Geothermal System

Abstract

Supplement data to Mukuhira et al. "Injection induced seismicity size distribution dependent on shear stress" published in Geophysical Research Letters (https://doi.org/10.1029/2020GL090934) This dataset contains the catalog of locations of microseismic events occurring in 2006-2007 that accompanied the fluid stimulation at the Basel Enhanced Geothermal System (EGS) site in Basel, Switzerland. The catalog includes event ID, occurrence date and time (trigger time), location, cluster ID and moment magnitude. The 1st row is a header line to explain data and units. The catalog was made using the multiplet analysis method by Asanuma et al., 2008 (Society of Exploration Geophysicists expanded abstract, 2008). For the detail, please see that paper, which is referenced below. Cluster ID 0 means non multiplet event (single event). The Catalog is the result of multiplet analysis performed using the 40-97 Hz frequency band of the waveforms.
