Seismicity map of the East Eifel Volcanic Field (EEVF) for the period between 1 Oct. 2017 and 28 Feb. 2018. a), b) and c) hypocenters of 88 microearthquakes known before applying A6-DFMSD. These events are already listed at least by one of the local seismological services: state seismological service of Rhineland-Palatinate (2023), Bensberg Observatory, University of Cologne (2023) or by Hensch et al. (2019). d), e) and f) hypocenters of 378 microearthquakes detected after applying A6-DFMSD. The green line shows the trend of the active Ochtendung fault zone, and the orange circle indicates the location of a newly discovered seismic cluster near the village Polch. Note: ten new DLF events (in purple) were discovered in the uppermost mantle
