From: An adaptive 6-dimensional floating-search multi-station seismic-event detector (A6-DFMSD) and its application to low-frequency earthquakes in the East Eifel Volcanic Field, Germany

Waveform examples (ground motion velocity, vertical component) along with their corresponding detection fields (windowed energy-proportional narrow bands, similar to Fig. 5f, but as spectrogram) for different event types detected by A6-DFMSD in the EEVF. Note: the signal from the music festival is similar to magmatic tornillo-shaped LF events (see e.g., Wassermann 2012). Records in the subplots are in UTC since: (a) 2019-08-07T21:13:44.20 at GLOK, (b) 2019-04-08T20:08:05.00 at DEP08 and (c) 2015-06-05T21:10:45.00 at DEP09
