摘要：Earthquakes are continuously monitored by a global network of several thousand seismic stations equipped withhighly sensitive digital seismometers. The Geological Surveyof Denmark and Greenland (GEUS) takes part in it by operating five seismic stations in Denmark and 18 in Greenland,some of the latter in collaboration with international partners. There are two main ways of detecting earthquakes fromdigital recordings of seismometers: (1) by a manual review ofthe data by an expert in processing seismic earthquake signals and (2) by an automatic method that uses a computerised algorithm to analyse the recordings.
