Matavanu

Matavanu is a volcano located on the island of Savai'i in Samoa. It is a young and historically active volcano, forming a distinct cinder cone that rises above the surrounding landscape. The volcano's most notable eruption occurred in 1905-1906, which was a significant event for the island. This eruption produced substantial lava flows that altered the topography of the western Savai'i, creating new land and destroying existing settlements and vegetation.

The 1905-1906 eruption was characterized by its effusive nature, with lava pouring out of vents near the summit. Ash and volcanic bombs were also ejected during the event, contributing to the volcanic deposits. The lava flows from Matavanu are known for their distinctive morphology, with ropey pahoehoe lava being a common feature. These flows have contributed to the rich volcanic soil found on Savai'i, which supports the island's agriculture.

While Matavanu is considered dormant, its proximity to populated areas and its historical eruptive activity mean it is monitored by geological authorities. The volcano's presence has shaped the cultural and geographical landscape of Savai'i, and it remains an important geological feature of the Samoan archipelago. Research continues to be conducted on its past eruptions and potential future activity.
