The NE wall of the Ksudach Shtyubel' crater is capped by bedded layers of tephra fall, pyroclastic flow, and pyroclastic surge deposits from the 1907 eruption. Three craters, 1.5, 0.6, and 0.4 km wide, formed along a NE-SW line. The eruption reduced the height of Shtyubel' cone by about 650 m and Shtyubel' lake filled the craters. The NE wall of Ksudach V caldera, inside which Shtyubel' cone was constructed, is visible at the top of the photo.
