Cartoon of the development of an inflated pāhoehoe sheet flow. From Self et al. (1998), modified. A. Cross sections; R and P are segregation figure with: R = vesicular silicic residuum and P = pipe vesicule. B. Map view.1. Liquid lava; 2. Visco-elastic crust; 3. Brittle crust. The thickness of the flow varies between 1 to 100 m and its length between < 100 m and > 10 km.

Pāhoehoe and ‘a‘ā basaltic lava flows are common on volcanic islands such as Hawaii, Reunion Island and Iceland. They are present in all LIP and giant lava flows identified in planetary volcanology. In terms of both areal coverage and total volume, pāhoehoe flows dominate basaltic lavas in subaerial and submarine environments on Earth. Several proc...
