Abstract

We developed an early detection system for debris flow occurrence based on seismic ambient noise measurements. The system consists of seismic ambient noise measurements, water level, and rain gages. The system continuously monitors relationship between ambient noise vibration, water levels, and precipitation. Debris flow occurrence would be detected as an irregular event among measurements. We installed the system along a mountain stream and monitored several months and established empirical relationship based on supervised machine learning.
