Dalk_clustering_events.tar.gz contains 909,720 events' waveforms detected near Dalk Glacier, in the Larsemann Hills, East Antarctica from 6 Dec 2019 to 2 Jan 2020. Original seismic data are recorded by 100 three-component short-duration seismometers. The preprocessing includes detrending, tapering and 1-Hz high-pass filtering and the detection method is STA/LTA (short term=0.5 s, long term=30 s, trigger threshold=10, detrigger threshold=3). AWS_environment.zip contains recordings of wind speed, wind direction and temperature at the Zhongshan Station from 6 Dec 2019 to 2 Jan 2020. unsupervised_clustering_code.zip contains the python codes of detecting by STA/LTA, feature extraction by an autoencoder and clustering by a Gaussian mixture model. ...
