A Review of Volcano Geophysics and Volcano-Monitoring Methods
1996In the past two decades, considerable progress has been realized in the geophysical studies of volcanoes aimed at explaining the source processes, modeling the magma feeding system, understanding the eruption dynamics, and forecasting the eruption onsets and their evolution. Seismicity patterns, detection of anomalous strain episodes through tiltmeters,

Infrared monitoring of volcanoes by satellite
Journal of the Geological Society, 1991Sensors on future satellite platforms will be used routinely for volcano monitoring, with infrared channels offering the potential to detect and measure temperatures of features such as lava bodies and fumarole fields. This is possible even though the surface temperature distributions associated with such phenomena are typically inhomogeneous at the ...

Using optics to monitor volcanoes
Optics and Photonics News, 2004Geochemical reactions and seismic activity lead to changes in the temperature and composition of volcanic gases. Laser spectroscopy enables online, in situ monitoring of volcanoes. In combination with fiber optic sensors, it may one day serve as the basis for a new type of eruption warning system.

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

Electrical and Electromagnetic Monitoring of Volcanoes
2022Electrical and Electromagnetic (EM) monitoring methods have not yet reached an operational level comparable to that of seismic and deformation monitoring. The electrical resistivity of a rock describes its ability to allow the movement of electrical charges. The resistivity of the electrolyte depends on its ionic composition and temperature. EM methods

GEODETIC MONITORING OF THE SANTORINI (THERA) VOLCANO
Survey Review, 2003Abstract Santorini (Thera) is a volcanic island complex dominated by a partly submerged caldera and famous from an eruption which buried the 3,500 years old Minoan town of Akrotiri. The volcano is active, and the last periods of its paroxysmal activity date to the 1920s, 1940s and 1950s, but in the last decades is dormant.

Laser Absorption Spectroscopy for Volcano Monitoring
Optics and Photonics News, 2006Recent advances in infrared laser spectroscopy may enable scientists to make accurate, in situ, real-time measurements of the isotopic composition of gas species emitted from volcanoes.

25 Volcano seismology and monitoring for eruptions
2002Seismology is considered one of the most useful tools for eruption forecasting and monitoring. Volcanoes are the sources of a great variety of seismic signals that behave differently than those from events on earthquake faults. Every recorded volcanic eruption is preceded by an increase in earthquake activity beneath or near the volcano and accompanied

Applications of Geophysical Methods to Volcano Monitoring
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2006, 2006The array of geophysical technologies used in volcano hazards studies - some developed originally for volcano monitoring - is breathtaking, ranging from satellite remote sensing to infrasound methods, including virtually every method used in resource exploration except large-scale seismic reflection. Passive seismic monitoring was arguably the earliest

An overview of satellite monitoring of volcanoes
2015The North Pacific region is remote and vast (5,000 by 2,000 km), and includes several hundred volcanoes in Kamchatka, the Kurile Islands, Alaska, and the northwestern U.S.A. (Figure 9.1).
