The island of Savai'i consists of a massive shield volcano and is still volcanically active. Other volcanoes on Savai'i include Mt Silisili, the highest mountain in Samoa and Mt Matavanu. The eruption of Mt Matavanu (1905-1911) destroyed villages on the central north coast of Savai'i which can be seen by the lava fields in Saleaula village.
In Samoan mythology the god of earthquakes is Mafui'e. Another mythical figure Ti'iti'i tricked the earthquake god so that Samoans could have fire to cook their food. Samoans well understood the connection between volcanic eruptions/earthquakes and tsunamis, as shown by the ancient term for tsunami - galuafi, or "wave of fire/volcano".
