- Аннотация: Volcanic eruption is one of the primary planetary resurfacing agent. Lava post-emplacement deformations and formation of surface of lava flows still need to be explored. Remote sensing data and its increasing availability allows to explore lava flows and landscape changes in different period of eruption with high periodicity. According to seismic data the 2012-2013 Tolbachik Fissure Eruption started on November 27, 2012. Landscape of Tolbachinsky Dol was strongly changed. Three new lava fields were formed with a total area is about 36 km2. The scientific and touristic infrastructure was damaged. Two scientific bases had been destroyed by lava flows. The road to Tolbachinsky Dol was blocked. The full picture of landscape transformation was analyzed on the basis of remote sensing data. Remote sensing data (optical and radar imagery) were regularly acquired during the whole eruption period. These series of radar interferometric pairs, optical imagery, digital elevation model (DEM) and results of fieldwork provide valuable information for complex thematic mapping. A series of thematic maps were created as a result of the study. They show dynamics of lava flow areas during eruption, provide complex maps of lava flow formation and describe landscape changes.
