Tinakula

Stratovulcano · Solomon Islands · 796 m

The northern side of the 3.5-km-wide Tinakula volcano at the NW end of the Santa Cruz Islands. The small island is the exposed portion of a stratovolcano that rises 3-4 km from the sea floor. A large breached crater extending from the summit to below the NW coast is visible to the right and has been the source of frequent eruptions dating back to at least 1595.

Sintesi geologica

The small 3.5-km-wide island of Tinakula is the exposed summit of a massive stratovolcano at the NW end of the Santa Cruz islands. It has a breached summit crater that extends from the summit to below sea level. Landslides enlarged this scarp in 1965, creating an embayment on the NW coast. The Mendana cone is located on the SE side. The dominantly andesitic volcano has frequently been observed in eruption since the era of Spanish exploration began in 1595. In about 1840 an explosive eruption apparently produced pyroclastic flows that swept all sides of the island, killing its inhabitants. Recorded eruptions have frequently originated from a cone constructed within the large breached crater. These have left the upper flanks and the steep apron of lava flows and volcaniclastic debris within the breach unvegetated.
