Global Volcanism Program | Image GVP-11440
The large volcanic complex at the center of this NASA International Space Station image (with north to the upper right) is Cerro del Azufre. The volcano lies just west of the Bolivian border, south of Salar de Ascotán (the light-colored area at the upper right). A youthful lava dome forms a small circular area below and to the right of the center of the image, and the Holocene San Pedro-San Pablo volcanic complex lies at the left-center.
