# Co-detection of micro seismic activity as early warning of gravitational slope failure

## TL;DR

This paper introduces a real-time early warning system for gravitational slope failure using co-detection of micro seismic activity, leveraging acoustic emissions and sensor networks to predict catastrophic events.

## Contribution

A novel, low-cost, autonomous method for early warning of slope failure based on micro seismic activity co-detection and acoustic emission analysis.

## Key findings

- Successfully applied to a steep rock glacier slope
- Demonstrated potential for real-world early warning
- Offers a robust, cost-effective monitoring solution

## Abstract

We developed a new strategy for Disaster Risk Reduction for gravitational slope failure: We propose a simple method for real-time early warning of gravity-driven failures that considers and exploits both the heterogeneity of natural media and characteristics of acoustic emissions attenuation. This method capitalizes on co-detection of elastic waves emanating from micro-cracks by a network of multiple and spatially distributed sensors. Event co-detection is considered as surrogate for large event size with more frequent co-detected events marking imminence of catastrophic failure. In this study we apply this method to a steep rock glacier / debris slope and demonstrate the potential of this simple strategy for real world cases, i.e. at slope scale. This low cost, robust and autonomous system provides a well adapted alternative/complementary solution for Early Warning Systems.
