Abstract
Three adaptive filters and one band-pass filter have been applied on one-channel seismic signals to detect and identify seismic wave arrivals, e.g. onsets. The adaptive filters are to be prefered, when noise and signal characteristics are varying. Also, the updated filter parameters provide additional interesting detection variables.
