Sollipulli


Sollipulli is an ice-filled volcanic caldera located northeast of Caburgua Lake and southeast of Llaima volcano, in the Araucania Region, Chile. The volcano has evolved in close contact with glacial ice and has some typical subglacial volcanic features such as hyaloclastite breccia and pillow lava. It differs from most calderas in that Sollipulli collapsed in a non-explosive manner. Since then volcanic activity has continued along surrounding ring faults which have produced lava flows and lava domes increasing the elevation of the caldera wall. The caldera is 4 km in average diameter and according to ground penetrating radar measurements it contains a maximum ice thickness of at least 550 m, but may even reach 650 m.
