Magnetic Monitoring of Volcanoes

2022
The 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 ...

Volcano monitoring applications of the Ozone Monitoring Instrument

Geological Society, London, Special Publications, 2013
AbstractThe Ozone Monitoring Instrument (OMI) is a satellite-based ultraviolet (UV) spectrometer with unprecedented sensitivity to atmospheric sulphur dioxide (SO2) concentrations. Since late 2004, OMI has provided a high-quality SO2dataset with near-continuous daily global coverage. In this review, we discuss the principal applications of this dataset

Monitoring active volcanoes

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 ...

Gravity Monitoring of Volcanoes

2022
The 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.

Satellite Monitoring of Volcanoes

1996
Ever-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.

Monitoring of Volcano deformation

2022
Monitoring 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.

Volcano monitoring by satellite

Geology Today, 1989
‘St Pierre, in the morning throbbing with life, thronged with people, is no more. Its ruins stretch before us, wrapped in their shroud of smoke and ashes, gloomy and silent, a city of the dead’. Thus was St Pierre described by the Vicar‐General of Martinique in the aftermath of the 8 May 1902 eruption of Mt Pelée.

Volcano monitoring goes into the deep

Science, 2016
Volcanology Axial Seamount is a large and active submarine volcano along the Juan de Fuca midocean ridge off the coast of the western United States. Eruptions in 1998 and 2011 were followed by periods of magma recharge, making it an ideal location to include in the Ocean Observatories Initiative Cabled Array. Wilcock et al.
