Classification of seismic signals at Villarrica volcano (Chile) using neural networks and genetic algorithms

Autor: Gonzalo Acuña, Gustavo Fuentealba, Max Chacón, Jorge Vergara, Gloria Curilem

Publikováno v: Journal of Volcanology and Geothermal Research. 180:1-8

Each volcano has its own unique seismic activity. The aim of this work is to construct a system able to classify seismic signals for the Villarrica volcano, one of the most active volcanoes in South America. Since seismic signals are the result of pa

Villarrica volcano, a 2,850 m basaltic-andesite stratocone in southern Chile (39°25'S-71° 42'W), has had an active summit lava lake (30-60 m diameter) since the last eruption in 1984-85. Current activity is characterised by mild strombolian activit
