Near-real-time design of experiments for seismic monitoring of volcanoes [PDF]
SeismicaMonitoring the seismic activity of volcanoes is crucial for hazard assessment and eruption forecasting. The layout of each seismic network determines the information content of recorded data about volcanic earthquakes, and experimental design methods ...

An Internet of Things (IoT) Application on Volcano Monitoring [PDF]
Sensors, 2019 In the last few years, there has been a huge interest in the Internet of Things (hereinafter IoT) field. Among the large number of IoT technologies, the low-power wide-area network (hereinafter LPWAN) has emerged providing low power, low data-rate communication over long distances, enabling battery-operated devices to operate for long time periods ...

Volcano deformation monitoring using GPS [PDF]
Journal of Spatial Science, 2007 Volcanic eruptions are often very destructive events, having a massive impact on the natural and human environment. In order to mitigate the effect of volcanic hazards such as pyroclastic flows, lahars and tsunamis it is necessary to closely monitor volcanoes. Ground surface deformation is recognised as a reliable indicator of an impending eruption and

Global Volcano Monitoring: What Does It Mean When Volcanoes Deform? [PDF]
, 2017 Currently, it is only possible to look inside an active volcano using indirect geophysical methods. One such method is to measure surface deformation, which results from subsurface magmatic or hydrothermal processes.

Geochemistry Geophysics Geosystems, 2019 Explosive eruptions that occur with little or no precursory unrest (less than a month) pose the greatest hazards from volcanoes to nearby populations. Here we focus on the preeruptive conditions for these explosive events, their triggers and how these ...

Insights on Hydrothermal‐Magmatic Interactions and Eruptive Processes at Poás Volcano (Costa Rica) From High‐Frequency Gas Monitoring and Drone Measurements [PDF]
Geophysical Research Letters, 2019 Identification of unambiguous signals of volcanic unrest is crucial in hazard assessment. Processes leading to phreatic and phreatomagmatic eruptions remain poorly understood, inhibiting effective eruption forecasting.

Volcano observatories and monitoring activities in Guatemala
Volcanica, 2021 The tectonic and volcanic environment in Guatemala is large and complex. Three major tectonic plates constantly interacting with each other, and a volcanic arc that extends from east to west in the southern part of the country, demand special attention in terms of monitoring and scientific studies.

Volcano Infrasound and the International Monitoring System [PDF]
Infrasound Monitoring for Atmospheric Studies, 2018 Volcanoes generate a wide variety of low-frequency (~0.01–20 Hz) acoustic signals, and infrasound technology is part of an expanding suite of geophysical tools available to characterize, understand, and monitor volcanic processes. We review recent advances in the field of volcano acoustics with an emphasis on scientific and potential civil application ...

Long range infrasound monitoring of Etna volcano [PDF]
Scientific Reports, 2019 AbstractAmong ground-based volcano monitoring techniques, infrasound is the only one capable of detecting explosive eruptions from distances of thousands of kilometers. We show how infrasound array analysis, using acoustic amplitude and detection persistency, allows automatic, near-real-time identification of eruptions of Etna volcano (Italy), for ...
