Gallego (ga‧lle‧go) also known as Mount Gallego is a volcano field located on the northwest side of the island Guadalcanal in the Solomon Islands. Volcanism here is the result of subduction, as the Indo-Australian Plate subducts under the Pacific Plate. Active during the Pleistocene, no historical eruptions have been documented.
