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.

Riassunto in ingleseTinakula is a conical stratovolcano which forms an island north of Nendo in Temotu Province, Solomon Islands. It lies at the north end of the Santa Cruz Islands. It is about 3.5 kilometres wide and rises 851 metres above sea level, rising three to four kilometres from the sea floor. The volcano was first recorded in eruption in 1595 when Spanish explorer Álvaro de Mendaña sailed past it during his second expedition across the Pacific Ocean. Tinakula has also been known in the past as Tamami or Volcano Island.
