NORSAR Kjeller, Norway Type of organisation: Research Institute Specialising in: Real-time transmission and automatic processing of seismic data from a network of arrays and single stations. Norway’s National Data Center for the CTBT. More specifically: Research on methods for explosion and earthquake monitoring. Rapid event locations and magnitude estimation. Participant in EU projects NERIES, SAFER and TRANSFER. Also specialising in: Seismotectonics, earthquake hazard and risk In-house capacity: Staff of 45, 10 researchers in Seismology TEWS Info Day, 31 Jan 2006, Paris

Potential Interest/Contribution to TEWS Real-time processing of data from seismic stations and arrays for obtaining early warnings of earthquakes that could potentially cause tsunamis. Obtain rapid event locations, depths and magnitude estimates from local, regional or globally distributed seismic networks of arrays and single stations. Application of global data from the CTBT network (IMS) and other on-line data sources in the context of tsunami warning. NORSAR has already access to and experience with data from the IMS. Training and supervision of scientists and students within the topics listed above, e.g., like the TA component in NERIES. Contact point: Dr. Tormod Kværna, Program Manager Tel: Url:

Desired Level of Cooperation There is no doubt that any TEWS needs strong input from seismology! We are interested to participate in any proposed effort where real-time processing of seismic data is included. We can also participate in evaluating tsunamigenic potentials, based on recent experience from a study of the Sumatra- Andaman Arc.
