Abstract

The main seismic-network assessment parameter is magnitude of completeness, which has been computed over a grid covering the Netherlands. This parameter describes the spatial variation of the minimum magnitude for which almost every earthquake can be located. The location of an earthquake can be determined if the earthquake signal is detected on at least three sensors. Detection has been modeled using expected signal-to-noise levels. Noise levels are the actually recorded noise levels at stations from the Netherlands seismic network, and stations just across the border in Belgium and Germany. The signal levels have been modeled for sources at 3 km depth, using a newly calibrated P-wave ground-motion prediction equation. Details are described in the following technical report: https://cdn.knmi.nl/knmi/pdf/bibliotheek/knmipubTR/TR405.pdf.
