in North America. Volcanic activity in central Mexico
Study of the structural changes in the Popocatepetl volcano in Mexico related to microseismicity by applying the lineament analysis to the Aster (Terra) satellite data. Abstract Mexico is one of the most volcanically active regions in North America. Volcanic activity in central Mex-ico is associated with the subduction of the Cocos and Rivera plates beneath the North American plate. Periods of ...
متن کاملHazards 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 کاملSatellite-based detection of volcanic sulphur dioxide from recent eruptions in Central and South America
Volcanic eruptions can emit large amounts of rock fragments and fine particles (ash) into the atmosphere, as well as several gases, including sulphur dioxide (SO2). These ejecta and emissions are a major natural hazard, not only to the local population, but also to the infrastructure in the vicinity of volcanoes and to aviation. Here, we describe a methodology to retrieve quantitative informati...
متن کاملThe respiratory health hazards of volcanic ash: a review for volcanic risk mitigation
Studies of the respiratory health effects of different types of volcanic ash have been undertaken only in the last 40 years, and mostly since the eruption of Mt. St. Helens in 1980. This review of all published clinical, epidemiological and toxicological studies, and other work known to the authors up to and including 2005, highlights the sparseness of studies on acute health effects after erup...
متن کاملUsing Statistical and Computer Models to Quantify Volcanic Hazards
Risk assessment of rare natural hazards— such as large volcanic block and ash or pyroclastic flows— is addressed. Assessment is approached through a combination of computer modeling, statistical modeling, and extreme-event probability computation. A computer model of the natural hazard is used to provide the needed extrapolation to unseen parts of the hazard space. Statistical modeling of the a...
