Data acquisition for volcano monitoring [PDF]
In the past decade, systems and techniques for volcano monitoring activities have improved rapidly. The scientific community focused on the development of new methods and techniques, while the electronic systems for experimental activity and monitoring networks were developed mainly by commercial companies.However, these commercial systems often do not

Monitoring temporal opacity fluctuations of large structures with muon tomography : a calibration experiment using a water tower tank [PDF]
Usage of secondary cosmic muons to image the geological structures density distribution significantly developed during the past ten years. Recent applications demonstrate the method interest to monitor magma ascent and volcanic gas movements inside ...

Monitoring active volcanoes: The geochemical approach
<p>The geochemical surveillance of an active volcano aims to recognize possible signals that are related to changes in volcanic activity. Indeed, as a consequence of the magma rising inside the volcanic "plumbing system" and/or the refilling with new batches of magma, the dissolved volatiles in the magma are progressively released as a function ...

The global volcano monitoring infrastructure database (GVMID)
Monitoring volcanoes is of the most importance in volcano risk mitigation to safeguard lives and economies. Thanks to recent technological advances, both on-ground and in space, our understanding of volcanic processes has improved significantly.

Volcano Infrasound and the International Monitoring System [PDF]
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 ...

In situ measurements of tropospheric volcanic plumes in Ecuador and Colombia during TC^4 [PDF]
A NASA DC-8 research aircraft penetrated tropospheric gas and aerosol plumes sourced from active volcanoes in Ecuador and Colombia during the Tropical Composition, Cloud and Climate Coupling (TC^4) mission in July–August 2007. The likely source volcanoes

Analysis of the Alaska Volcano Observatory's Response Time to Volcanic Explosions-1989 to 2016
A major goal of volcano monitoring is the rapid identification of volcanic explosions and subsequent warning of associated hazards. Between 1988 and 2016 the Alaska Volcano Observatory (AVO) responded to at least 54 separate volcanic eruptions.

Monitoring of Merapi Volcano Deformation Using Interferometry Synthetic Aperture Radar (InSAR) Technique [PDF]
The Merapi volcano is the most active volcano in Indonesia until now, because of eruption occur every two or five years. To minimize the impact of volcanic eruptions need to monitor the volcanic activity, one effort in monitoring is to monitor the ...
