A spectacular geologic outcrop at the western Yasur caldera rim exposes a 3-4 meter thick, solid red deposit which in fact probably is a deposit from a spatter-rich pyroclastic flow, welded so well together that it appears like a lava flow. A fine-grained base layer and loose or poorly welded spatter at the top can be seen as well.
Btw, very similar deposits can be observed on Santorini (e.g. "Upper Scoria 2") where they have become subjects of numerous studies and are now famous as perfect examples for this unusual (and previously unrecognized) type of pyroclastic flows.  (Photo: Tom Pfeiffer)

Numerous hollows many of which still contain charcoal are present in certain sections of the ash flow. When the pyroclastic avalanche flowed over a forest, many trunks and branches of trees were incorporated into the flow and their shape preserved in the deposit. (Photo: Tom Pfeiffer)
