A near real-time framework for monitoring very-long-period signals at volcanoes.

ABSTRACT: Real-time seismological applications are essential for monitoring active volcanoes, offering valuable tools for the early detection of volcanic unrest and eruption. Very Long Period (VLP) seismicity, commonly observed at open-vent volcanoes with mild and persistent explosive activity, is a key indicator of volcanic activity intensity as changes in the rate of occurrence and VLP event magnitude can be a signal of impending unrest. In this study, we introduce a new method for the automatic and near real-time detection and characterization of VLP seismicity. Our approach was tested on Stromboli Volcano (Italy), where VLP seismic activity has been well-documented for over two decades. The detection algorithm is based on three-component amplitude analysis, derived from waveform polarization and
