Intra-arc continental rifts North Island, New Zealand. Red approximately delineates the active modern Taupō Rift, yellow the inactive old Taupō Rift, and purple the still active Hauraki Rift. The rifts intersect in an area where volcanic deposits over 2 million years have buried non active fault systems. There is very complex active normal faulting in the Taupō Rift aligned mainly (apart from at the inland termination of the rift) with the rift alignment. | |
