The caldera wall seen here is the northern and eastern portion of the youngest Mayor Island caldera, which formed about 6300 years ago. The 2.2 x 2.5 km caldera floor is covered by young lava flows, the latest of which may have been erupted only about 500-1000 years ago.

The caldera wall at the upper right was created during the youngest caldera-forming eruption of Mayor Island about 6300 years ago. Major explosive eruptions at this time produced more than 1 cu km of tephra, which fell across the Bay of Plenty on North Island. The 2.2 x 2.5 km wide caldera was subsequently partially filled by lava flows and domes, the latest of which may have been erupted as recently as 500-1000 years ago.

Mayor Island, in the Bay of Plenty, is seen here from the west. The low, 4-km-wide island, also known as Tuhua, is the summit of a broad, 15-km-wide lava shield. A 3-km-wide caldera formed during 2 or 3 collapse events, the latest of which followed a major explosive eruption about 6300 years ago. Mayor Island was recognized as an active volcano only within the past two decades. Its latest eruption may have occurred only 500-1000 years ago.
