Journal of the Geological Society, 1991
A meeting of the Volcanic Studies Group was held at Burlington House on 6 December 1989, to review establkhed and innovative techniques used in monitoring active volcanoes. Ten of the fourteen papers offered were presented orally. The meeting was topical, being held on the eve of the United Nations ...

Magnetic Monitoring of Volcanoes
2022The Earth's ambient magnetic field is the sum of the fields produced by several sources, both internal and external, stable or variable in time. To measure variations in the magnetic field created by volcanic phenomena, generally of very low amplitude, it is necessary to be able to know the variations created by other internal or external phenomena ...

Satellite Monitoring of Volcanoes
1996Ever-increasing population densities of volcanic regions around the world dictate that the potential risks of any eruption are also increasing. Rapid developments in remote-sensing science in recent years vastly expand our capabilities to monitor volcanoes across the entire electromagnetic spectrum.

Gravity Monitoring of Volcanoes
2022The Earth's gravity field varies over time due to external and internal causes, but in minute proportions compared to its average value. The basic principle of microgravity monitoring is that changes in Earth's gravity can reflect deep mass transfer processes, often associated with surface deformation.

Monitoring remote volcanoes: The 2010–2012 unrest at Sotará volcano (Colombia)
Journal of Volcanology and Geothermal Research, 2017Abstract Sotara is a little known andesitic-dacitic stratovolcano in southern Colombia (Central Cordillera, Cauca Department). Its remote location and the lack of accessible roads make studying and monitoring Sotara volcano difficult. No historical eruptions are known, though there is current geothermal activity. Between the fall of 2010 and the fall

Monitoring of Volcano deformation
2022Monitoring ground surface deformation is an essential component of volcano monitoring, along with other techniques, such as seismology, geochemistry and geology. This chapter presents the different sources at the origin of the deformation observed in a volcanic context, followed by a review of the various techniques used for measuring such deformation.
