Under a blood red sky A guide to Rangitoto

Learn about Auckland’s largest and youngest volcano – Rangitoto.

A basaltic shield volcano that last erupted not long after the arrival of Polynesians in the Auckland region (c. 1280 AD), Rangitoto has a complex history.

An “oceanic” island, Rangitoto’s flora and fauna derives from long-distance dispersal.

The name – Rangitoto – is Māori for “blood red sky”.

Among the island’s volcanic features are overlapping lava flows on the lower slopes and lava tunnels linked by lava trenches on the south-eastern flanks.

The summit scoria cones rise from a “moat” at the top of the lava slopes.

Two outer cones – North and South – flank the Central cone and crater.

Summit scoria has been formed by episodic “fire fountaining”.

The Guidebook for Rangitoto Island Field Trip was created in conjunction with the Dynamic New Zealand, Dynamic Earth: Auckland 2017 Annual Conference of the Geoscience Society of New Zealand.
