This page is for extraction of event data from the seismic catalogue that is maintained by the NNSN. The catalogue is the result of data processing at the University of Bergen with contributions from NORSAR. Additional contributions are made by the USGS, EMSC, ISC, GEUS, SNSN, BGS, HEL. The catalogue available here goes back to historic times (1060-1970), but mostly contains events from instrumental times (1970-now). Note that completeness has changed over time and the catalogue includes earthquakes, explosions and other events. Please use the query builder (following the FDSN Event Web Service Specification) below to get data:
