A large body of magma, capped by a hydrothermal system, still exists beneath the caldera. |
The continuing uplift of the caldera rim can be explained by the restricted size of the magma's exit route. |
Other ephemeral lakes develop in volcanic craters or collapsed caldera systems. |
Mayor Island is a shield volcano with a caldera in the western part of the Bay of Plenty, off the east coast of New Zealand. |
These landslides were embayed by the lava that flooded the central caldera floor. |
This landslide material was then embayed by lava when the central caldera was flooded. |
