The Volcano known as Bob south of La Restinga in El Hierro has started to sprout fiery flames. They where first discovered by commenter Newby, and later cought on video by our own helper Sissel, and then by Lori (known as Buenamusa in here).
We at Volcanocafé extend our heartfelt gratitude for their hard work.
What the flames consist of is as yet unknown. A tentative hypothesize has been put forth by Peter Cobbold that it could be methane gas released from a sedimentary layer. Another theory is that it could be the beginning of Surtseyan style roostertails. Time will tell what it is.
Update: According to Lori (Buenamusa) they are large volcanic stones called Pyroclasts that flashglow as they surface. It makes sense, because then what looks like flame is the light from the glow hitting the steam puff they produce. It also makes sense that these stones would become hotter and more “glowy” as Bob comes closer to the surface.
This is the Video produced by Sissel.

Update 2: Here is a third video produced by Julio del Castillo Vivero. It contains blow ups of the flares that are slowed down for clarity.
