PGV levels and location uncertainty for the Winde events in August 2023

In August, 2023, two events occurred in the village of Winde in Drenthe; the first earthquake at 22-08-2023 18:39:08.69 UTC with a local magnitude of 1.56, the second earthquake at at 23-08-2023 12:05:48.6 UTC with a local magnitude of 1.71. Both events were detected by the KNMI network (KNMI , 1993) and located near-real time with the Hypocenter method (Lienert et al., 1986). These fast solutions use an average 1D model for the north of the Netherlands (Kraaijpoel and Dost, 2013). In this report, updated epicenters and their uncertainties are listed. Moreover, peak-ground velocity (PGV) levels are extracted from the recordings. These are used, together with a ground motion prediction equation, to find out whether it is likely that PGV levels occurred of 2 mm/s and higher.
