Zusammenfassung |
This paper presents the development and applications of a
software-based quality control system that monitors volcano
activity in near-real time. On the premise that external seismic
manifestations provide information directly related to the
internal status of a volcano, here we analyzed variations in
background seismic noise. By continuous analysis of variations in
seismic waveforms, we detected clear indications of changes in the
internal status. The application of this method to data recorded
in Villarrica (Chile) and Tungurahua (Ecuador) volcanoes
demonstrates that it is suitable to be used as a forecasting tool.
A recent application of this developed software-based quality
control to the real-time monitoring of Teide – Pico Viejo volcanic
complex (Spain) anticipated external episodes of volcanic
activity, thus corroborating the advantages and capacity of the
methodology when implemented as an automatic real-time procedure. |
