REVEALING THE POSTVOLCANIC ACTIVITY USING SATELLITE IMAGES AND GROUND MEASUREMENTS (CASE OF THE KUNASHIR ISLAND)
Remote sensing data is a valuable source of information about geographic objects and processes, including postvolcanic activity. Manifestations of postvolcanic activity are associated with the allocation of large amounts of heat, therefore they are displayed on the thermal infrared satellite images. This paper discusses the methods of revealing the manifestations of postvolcanic activity on the thermal infrared satellite images of high spatial resolution, as well as satellite images of other spectral ranges. Manifestations of postvolcanic activity of the Kunashir Island are examined. The work is divided into 2 parts which are the calculation of the Earth's surface temperatures using thermal infrared satellite images and revealing the interpretive signs identifying the manifestations of postvolcanic activity on thermal infrared satellite images. Recommendations for the use of thermal infrared satellite imagery to reveal the manifestations of postvolcanic activity are presented.
