Usu is along the SW boundary of the larger Toya caldera and is shown here in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top). The Usu edifice summit contains the collapse scarp in the center of the image, which is 1.5-2 km across and contains both domes and cryptodomes. Additional cryptodomes surround the scarp from the NW around to the SE.
