Hazards of Volcanic Gases
aerosol A colloidal dispersion of liquid particles in a gas, e.g., SO2, which will react with the OH radical in the atmosphere to form tiny droplets of sulfuric acid (H2SO4). hazard In a volcanic context, hazard refers to the phenomena produced by a volcanic event and is directly related to Risk, where Risk1⁄4Hazard Vulnerability, with vulnerability referring to the consequences for population ...
متن کاملRemote Sensing of Permafrost-related Problems and Hazards
Modern remote sensing techniques can help in the assessment of permafrost hazards in high latitudes and cold mountains. Hazard development in these areas is affected by process interactions and chain reactions, the ongoing shift of cryospheric hazard zones due to atmospheric warming, the large spatial scales involved and the remoteness of many permafrost-related threats. This paper reviews grou...
متن کاملAn Overview of Infrared Remote Sensing of Volcanic Activity
Volcanic activity consists of the transfer of heat from the interior of the Earth to the surface. The characteristics of the heat emitted relate directly to the geological processes underway and can be observed from space, using the thermal sensors present on many Earth-orbiting satellites. For over 50 years, scientists have utilised such sensors and are now able to determine the sort of volcan...
متن کاملProgress in the Infrared Remote Sensing of Volcanic Activity
Volcanic activity essentially consists of the transfer of heat from the Earth’ interior to the surface. The precise signature of this heat transfer relates directly to the processes underway at and within a particular volcano and this can be observed, at a safe distance, remotely, using infrared sensors that are present on Earth-orbiting satellites. For over 50 years, scientists have perfected ...
متن کاملGround Based Ultraviolet Remote Sensing of Volcanic Gas Plumes
Ultraviolet spectroscopy has been implemented for over thirty years to monitorvolcanic SO₂ emissions. These data have provided valuable information concerningunderground magmatic conditions, which have been of utility in eruption forecastingefforts. During the last decade the traditionally used correlation spectrometers have beenupgraded with miniature USB coupled UV spectrometers, opening a se...
