- A major flow has broken out from the southern shields and headed in the direction of the northwest part of the Royal Gardens subdivision at about the 1600 elevation and four miles from the ocean. The flow on the eastern edge was composed of gas rich lava which forms a frothy crust known as shelly pahoehoe. This crust easily folds over itself as it is carried downstream and encapsulates gas pockets within. These voids within the crust allow the thin crust to break open like egg shells and may pose a hazard if walked on after they cool. Its appearance is very distinct so it is very easy to avoid.

@modemeyes The lava seen here doesn't go very far before it becomes solid, but it provides insulation for the supply of lava upstream which will continue to flow under the crust and which itself will become insulation. Eventually, if the supply is not interrupted, it will form an established tube all the way to the ocean. The scientists say that it will only lose about 10 degrees F from the original 2000 as it travels inside the tube about seven miles from the source to the ocean.
so peaceful and noble , i do geology at college and its great
:o
Bellissimo come sempre.
I like pahoehoe (mainly)
Uy, mind your step on shelly lava! :)
