Monitoring state of natural environment of territories with active volcanism

Abstract

State of natural environment in situation of active volcanism depends on power and frequency of eruptions. To understand scale and nature of changes in essence environment of the territories adjacent to active volcanoes, it is necessary to conduct monitoring based on the use of remote sensing data of the Earth. Purpose of the work is to summarize the results of the author's research and the work of his predecessors, as well as to propose a technology for monitoring state of natural environment of territories with active volcanism. The research uses methods of decoding satellite images, field observations, geoinformation and retrospective analysis. The developed technology can contribute to operational assessment of impact on state of environment, as well as prediction of volcanic hazards for territories adjacent to active volcanoes. The results of research confirm danger of volcanic processes for environmental components. There is a relationship between thickness of tephra deposits and rate of succession.
