The Netherlands Seismic and Acoustic Network NL is the national network of sensors deployed by the Royal Netherlands Meteorological Network (KNMI) to monitor seismic and acoustic events. The history of the Netherlands Seismic and Acoustic Network dates back to the beginning of the 20th century, however the modern network started in 1993 with the installation of a Streckeisen STS-1 sensor in Heimansgroeve (station code HGN). Since then the network gradually extended and evolved into a real-time, continuous recording and processing system of high quality seismic and acoustic data from broad band seismometers, borehole geophone stations, accelerometers and infrasound sensors. Today, the network is the leading monitoring network in the Netherlands to detect induced and tectonic earthquakes as well as acoustic signals in the Netherlands and beyond. The network comprises about 15 broad band seismometers, 99 borehole geophone stations, 97 accelerometers and 43 infrasound sensors. Data from all sensors are openly ...
