The Falso Azufre volcanic complex, covering 387 km2 at the Chile-Argentina border, was constructed largely by lava flows up to 7 km long and 4 km wide, shown in this April 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 22 km across). The crater of the Kunstmann edifice is in the upper left corner, and the eastern domes, coulees, and lava flows are to the far right. The summit region craters are aligned along a NW-SE trend to the W (the Falso Azufre edifice), and along a ENE-WSW trend on the eastern side (the Dos Conos edifice).
