  ***LenDB*** consists of seismograms recorded from multiple different seismic detection networks from across the globe [1, 2]. The processed dataset consists of 1,244,942 multivariate time series, with 3 channels, each of length 540, with two classes: earthquake and noise. This version of the dataset has been split into cross-validation folds based on seismic detection network (i.e., such that seismograms for a given network do not appear in both a training and validation fold).
