Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Reporoa. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Reporoa page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Deformation History

There is no Deformation History data available for Reporoa.

Emission History

Steaming Champagne Pool is one of many thermal features of the 10-km-wide Reporoa caldera. The caldera was formed about 230,000 years ago during the eruption of the Kaingaroa ignimbrite. No eruptions have occurred since the Pleistocene in the caldera, but hydrothermal explosions took place in the Waiotapu thermal field north of the caldera at the time of the Kaharoa eruption of the Okataina volcanic centre about 800 years ago. The Broadlands (Ohaki) hydrothermal field is located south of the poorly defined caldera margin.

Bubbling mud pots at a thermal area of New Zealand's Reporoa caldera form geometric patterns. Mud pots form in thermal areas where the gas phase is dominant over the liquid phase and extensive hydrothermal alteration of rocks has occurred, producing fine-grained, clay-rich material.

Multi-colored Bridal Veil Falls were formed from silica terraces created when mineralized water poured over from the Primrose Pool of the Wai-O-Tapu thermal area. The noted hydrothermal area lies within the 10-km-wide Reporoa caldera, which was formed during the Pleistocene in the Reporoa-Broadlands basin near the western margin of the Taupo volcanic zone. Large hydrothermal explosions took place from the Wai-O-Tapu thermal area at the time of the Kaharoa eruption of neighboring Tarawera volcano (Okataina Volcanic Centre) about 700 years ago.
