Some of the lava is not fragmented and flows from the vent as a lava flow.

For example, geologists have identified at least 30 young cinder cones on the Mount Edziza volcanic complex, a large shield volcano in northwestern British Columbia with an area of 1,000 square kilometres (390 sq mi).

Active lava lakes comprise young crust that is repeatedly destroyed and regenerated.

Convective motion of the underlying lava causes the crust to break into slabs and sink.

The IPCC is currently in its Sixth Assessment cycle.
