Maori Volcano Gods

This article on the Maori volcano gods explains lots of interesting facts including the creation myth....

Maui used a jawbone as a hook and some flax soaked in blood as bait.  Maui pulled up a gigantic fish called Hahau-whenua; the fish was so big that there were fires burning and people walking on its back.  Maui's brothers started to cut and crimp the fish, but it began to struggle.  The fish thrashed back and forth, and its back was thrown into wrinkles and folds.  The land that was created from this fish is now known as Te Ika-a-Maui, or the fish of Maui, and it is covered in mountains and valleys.  Of these mountains, the volcanoes Taupo and Tongariro make up the belly of the fish (Anderson, 1969).

...and a story that describes volcanic eruptions being triggered in a line.....

The sisters called upon fire demons that began swimming underwater toward Ngatoro.  They first came out of the water at White Island to see where they were, and the land burst into flames that are still burning.  The demons continued on underwater until they reached Ngatoro and burst through the summit of the mountain, thus creating the volcano Ngauruhoe.  Ngatoro was saved by the warmth, but Auruhoe had already died.  Ngatoro then took Auruhoe's body and threw it into the volcano.  The underwater path of the fire demons can still be seen, for everywhere they surfaced is now a thermal area (Vitaliano, 1973).

...and a story about a love rival's fight....

Taranaki and Ruapehu fell in love with Tongariro and proceeded to fight for her.  Taranaki threw himself at Ruapehu, but Ruapehu sprayed scalding water from his lake one Taranaki.  In retaliation, Taranaki threw stones at Ruapehu destroying his once beautiful summit.  Ruapehu was able to swallow the fragments of his cone, melt them, and spit them back at Taranaki.  Taranaki retreated up the coast to where he lives now, plotting his revenge (Vitaliano, 1973).
