An algorithm for rockfall events automatic detection and classification in seismic monitoring

A seven months-long seismic monitoring of a former quarry in Central Italy was performed by means of four tri-axial velocimeters that acquired continuously at 200 Hz. During this monitoring period a man-induced rockfall simulation was performed, releasing 90 blocks of different size from the benches of the quarry. During the test, several rockfall signals and a variety of other natural events have been recorded. The transient analysis allowed to calibrate an algorithm for seismic events automatic detection and classification written ad hoc, within the Matlab environment.
