Last day I watched the video Electric Discharge and Surface Formation
by Mr2Tuff2. Watching from 7:53
I came to think about the strange lava formation Dimmuborgir (Wikipedia)
close to lake Mývatn in Iceland (see attached image). Dimmuborgir is a circular area with lava pillars and other formations that I've visited three times, most recently in 2015. According to wikipedia
the formations were created when a lava lake collapsed. I guess that they think that the pillars are created like underwater lava pillars like these:Lava pillars (noaa.gov)
I found that hard to understand when I read it so could these formations instead have been formed by electric discharge?
Another type of formations in the Mývatn area are the pseudocraters or rootless cones
. Some av them are double rootless cones:Double rootless cones around Lake Myvatn in Iceland, as analogues to double cones in Athabasca Valles, Mars
These looks much like the crater in a crater at 5:45
in the video above.
The pseudocraters are supposed to have been created by steam exploding through lava. Could these have been formed by electric discharge?
