Its filling began in 1995 and ended in 1997. The reservoir of 234.5 million m3 capacity is shallow, between 20 to 50 m of water column, on average. Until 2011 the seismic activity in this region was sparse, some 1 event trimonthly. However, in November 2011 more than 60 events occurred. Such bursts of activity, separated by low activity periods, continue to appear. Since August 2013 the area is monitored by a local seismic network. The setup allows to accurately locate the epicenters and to determine source mechanisms for stronger events. The events are clustered and aligned along NE-SW direction and their mechanisms are very similar, indicating N-S strike slip faulting. This and the irregular pattern of activity suggest that this seismicity is triggered by the reservoir impoundment. date: 2015-08 date_type: published publication: Acta Geophysica volume: 63 number: 4 id_number: doi:10.1515/acgeo-2015-0026 issn: 1895-7455 official_url: http://dx.doi.org/10.1515/acgeo-2015-0026 access_IS-EPOS: unlimited owner: Publisher citation: Bialon, Wojciech and Zarzycka, Ewa and Lasocki, Stanislaw (2015) Seismicity of Czorsztyn Lake Region: A Case of Reservoir Triggered Seismic Process?
