SNSN Network Information

Network code: UP
Network name: The Swedish National Seismic Network (SNSN)
Operated by: Uppsala University, Uppsala, Sweden
Start date: 8 October 1904
Deployment region: Sweden [55.6,11.1; 68.3,23.4]
Size: Approximately 65 active permanent stations; more than 2.8 GB/day
Data availability: Real-time continuous data from 10 stations (see map below) available from ORFEUS. Scanned paper recordings from the Uppsala Wiechert 1904 - 1998 are available from the EUROSEISMOS project seismogram request form or on request from the SNSN.
Contact for data requests: data@snsn.se

Information: The Swedish National Seismic Network (SNSN) started with the installation of a Wiechert seismograph in Uppsala in 1904. Since 1998 the SNSN is a part of the Department of Earth Sciences at Uppsala University. The SNSN operates the only permanent, earthquake focused seismic network in Sweden and is responsible for detecting and recording earthquakes in Sweden. Near real-time automatic event detection has been an integral part of SNSN operations since 2000 and continuous 100 Hz data has been collected since 2008. Information services is an important part of SNSNs operations, which includes automatic risk assessment of large global events to Swedish crisis management authorities, contacts with the authorities, information to media and the public and outreach to schools. The SNSN operates 65 permanent stations, from Lund in southern Sweden to north of Torneträsk. The instruments are mostly Güralp 3T, one-third 120 s and two-thirds 30 s, with Güralp digitizers sampling at 100 Hz. The sensors have unusually high gain, mostly 2x10,000 V/m/s, in order to facilitate detection of microearthquakes in the regional size network. With an average station spacing of 66 km, the SNSN is complete to magnitude 0.5 within the network. The SNSN exports real-time data from 10 stations to ORFEUS and additional real-time data from stations along the borders to the Danish, Finnish and Norwegian seismic networks. For inquiries about data from other stations than the ones exported to ORFEUS, please contact the SNSN.
