Detection of debris-flow events from seismic signals using Benford’s law

The first step in building an early warning system using seismic signals is to automatically identify events of interest. Here, the digit distribution generated by debris flows and other surface processes was calculated validate compliance with Benford's law (BL). A detector model for flow introduced based on amplitude range goodness fit BL. We show that flows, landslides, bedload transport follow These release more energy last longer than rockfalls, which do not In test dataset 1224 samples, accuracy identifying 0.75.
