Volcanoes are destroyed again by the formation of craters, collapse scars, landslides, and calderas. A volcano is constructed as a result of the deposition of lava flows, lava domes, cinder- or stratocones, shallow magma intrusions, among others. Volcanic edifices develop as a result of interactions between volcano growth and mass wasting - constructive and destructive processes, respectively. We develop a conceptual model emphasizing the relevance of structural trends, namely, 1) a SW-NE-oriented (possibly regional) structure and 2) the infilled amphitheater and its decollement surface, both of which are vital for understanding the directions of growth and collapse and for assessing the potential hazards at both Shiveluch and dome-building volcanoes elsewhere. This work sheds light on the structural architecture dominated by a SW-NE lineament and the complex interplay of volcano constructive and destructive processes. The eruption and collapse removed 0.11 km 3 of the dome edifice and led to the formation of a new central SW-NE-elongated crater with dimensions of 430 m × 490 m, a collapse scar at the eastern part of the dome, and pyroclastic density currents that traveled ∼12 km downslope. Then, the large Augexplosive eruption occurred, followed by partial dome collapse, which was initially directed away from this SW-NE trend. As the amphitheater infilled, new eruption craters emerged along a SW-NE alignment close to the amphitheater rim. Our results show that a new massive lava lobe gradually extruded onto the SW flank of the dome, concurrent with magmatic intrusion into the eastern dome sector, adding 0.15 km 3 to the lava dome complex. We investigate the evolution of the 2018–2019 eruption episode and evaluate the morphological and structural changes that led to the Augexplosive eruption and partial dome collapse. We collect and process a multisensor dataset comprising high-resolution optical (aerial and tri-stereo Pleiades satellite), radar (TerraSAR-X and TanDEM-X satellites), and thermal (aerial and MODIS, Sentinel-2, and Landsat 8 satellites) data. Here, we analyze the recent activity of Shiveluch volcano, Kamchatka Peninsula, characterized by repeated episodes of lava dome growth and destruction due to large explosions and gravity-driven collapses. However, details of the structural architecture affiliated with renewed volcanic activity and the influences of regional structures remain poorly understood. 4Department of Earth Sciences, University of Turin, Turin, Italyĭome-building volcanoes often develop by intrusion and extrusion, recurrent destabilization and sector collapses, and renewed volcanic growth inside the collapse embayment.3Institute of Photogrammetry and GeoInformation, Leibniz University Hannover, Hannover, Germany.2Institute of Volcanology and Seismology FEB RAS, Petropavlovsk-Kamchatsky, Russia.1German Research Centre for Geosciences GFZ, Potsdam, Germany.Vassileva 1,3 Francesco Massimetti 1,4 Thomas R.
