The Hooghalen event on 01-10-2023:19:55:06.29 with a local magnitude of 1.89 was detected by the KNMI network (KNMI , 1993) and located near-real time with the Hypocenter method (Lienert et al., 1986). This fast solution uses an average 1D model for the north of the Netherlands (Kraaijpoel and Dost, 2013). In this report, an updated epicenter and its uncertainty is derived. Moreover, peak-ground velocity (PGV) levels are extracted from the recordings. These are used, together with a ground motion prediction equation, to find out where PGV levels of 2 mm/s and higher may have occurred.
