GFZ contribution to the COSEISMIQ seismic network

In the frame of the EU-project COSEISMIQ (COntrol SEISmicity and Manage Induced earthQuakes) natural and induced seismic events were monitored in Iceland. A temporary seismic network has been deployed in the Hengill geothermal region in Iceland, where the two largest geothermal power plants of the country are currently in operation. The GFZ contribution was the installation and operation of a small-scale seismic array in 2019-2021 in the vicinity of the broadband station MEI05 (ETH), in cooperation with ISOR (Iceland), ETH (Zurich) and DIAS (Dublin). This dataset is particularly valuable since a very dense network was deployed in a seismically active region where both induced and natural seismicity are occurring. For this reason, the collected COSEISMIQ-dataset can be used within a broad range of research topics in seismology ranging from the development and testing of new data analysis methods to induced seismicity and seismo-tectonics studies.

在欧盟项目COSEISMIQ（控制地震活动与管理诱发地震，COntrol SEISmicity and Manage Induced earthQuakes）框架下，研究团队对冰岛境内的天然地震与诱发地震事件开展了监测工作。研究团队在冰岛亨吉尔地热区部署了临时地震台网，该区域目前运行着冰岛两座规模最大的地热发电厂。本项目中，GFZ的贡献为与冰岛ISOR、苏黎世联邦理工学院（ETH Zurich）及都柏林DIAS合作，于2019至2021年在宽频台站MEI05（ETH）周边架设并运维一套小型地震台阵。该数据集具备极高科研价值：其部署的台网密度极高，且覆盖区域为同时存在诱发地震与天然地震活动的地震活跃区。正因如此，本次采集的COSEISMIQ数据集可广泛应用于地震学领域的诸多研究方向，涵盖新型数据分析方法的开发与测试、诱发地震及地震构造学研究等。
