3331 20180105073429.0 POSTER-2018-0002 Van Camp, M. The Belgian seismic and accelerometric networks 2017 2017-10-26 We present the Belgian seismic (31 stations, of which 9 boreholes) and accelerometric networks. The accelerometric network is composed of 18 ETNA-Episensors, and of 64 low-cost sensors all over the Belgian territory (“AcceleROB”). AcceleROB aims at measuring the ground motion whenever an earthquake of magnitude larger than 3.0 would occur. The project has been launched publicly in 2015 and, in 2017, 72 AcceleROBs are installed at private voluntary hosts. Data from all stations flow in real time towards the ROB where it is processed and archived. A web portal has been created so hosts can visualize the recordings done in their home in near-real time. The seismic stations provide data continuously through Internet (ADSL or LTE). The ETNA stations still use analog modem connections, providing an independent way to download data (triggered-based system). Stations available in realtime at Orfeus: • BE.UCC – Uccle Borehole (Guralp) – Dead • BE.BOST – Oostende Borehole (Guralp) – Dead • BE.BEBN – Eben-Emael • BE.RCHB – Rochefort Cave • BE.MEM – Membach Archived at IRIS: • BE.MEM • BE.UCC • SG.MEMB • SG.RCHS NO Belgian seismic network Belgian accelerometric network Lecocq, T.
