The relocated villages of Gaga'emauga district on the main island Upolu was a result of 1905 - 1911 volcanic eruptions of
Mt Matavanu, situated about 11 km inland from
Matautu on the central north coast. Lava flows from eruptions destroyed villages in its path, including Saleaula and Salago villages, transforming the northern half of this district into lava fields which are still visible today, especially at Saleaula. The people of the affected areas were evacuated to Upolu, where they established the villages of
Le'auva'a and
Salamumu. Despite the move, they still retain their traditional links and ''fa'alupega'' (genealogy) affiliations to Gagaemauga. The names Leava'a and Salamumu denote the events of the 1905 Mt Matavanu eruption. In recent years, a few families have re-built houses on the lava fields where vegetation is still sparse. ==Itu o Tane==
