Volcanoes of Samoa – Part 2 of 2

Google Maps screen capture of Tutuila Island. Multiple volcanoes are clearly visible. Collapsed and heavily eroded Pago volcano is barely visible. Note the lack of barrier reef surrounding the island, which should indicate how rapid the island is subsiding back into the ocean.

Volcanoes of Samoa – Part 1 of 2

Google Maps screen capture of the Samoan Islands. The two main islands of the nation of Samoa are clearly visible left of center, Savai’i and Upolu. The main islands of American Samoa also visible, the American Samoa label is hiding Tuluila. To its east are Ofu – Olosega, Ta’u and the Vailulu’u seamount. Sea floors are up to 5,000 under the island chain. Multiple seamounts, some related, some not, are visible. The curved structure in the lower right is the transition of the Kermadec – Tonga Trench into the Vitaz Trench, a source of significant tectonic stress in the region.

Are there Volcanoes in FIJI 🇫🇯 ?

(https://www.tourismfiji.com)

When the news reported multiple volcanoes erupting in Vanuatu – when new volcanoes appeared near Tonga Islands – when earthquakes shook most of Melanesia left right and center – I have often wondered if, or why, there are no volcanoes on the Fiji Islands? Well, you probably guess the answer – of course there are! They are just not very busy at the moment, so they may escape our attention, and may lull the residents in false security, too. The three that are mentioned by the GVP are Taveuni and Koro Islands, and Nabukelevu which occupies the SW end of Kadavu Island.
