Here's something you don't see every day - giant chunks of rock, floating down the river!



Obviously makes quite a difference if the river is one of lava rather than water. The collapse of (part of) the north wall the other day was also an impressive spectacle.

As someone who's always had an interest in geology, from my earliest memories, I find it quite fascinating to watch a relatively near-by landscape being made and re-made in real time. :geek:

The scale of this carry on has always astonished me

An example, a few miles across the water on the north west coast of Tenerife there is an old road down to the sea ( San Marcos ) hacked into the lava. A few snaps of the up-side

Anyone know where the 'Satellite imagery showing the plume over Rome via northern Morocco and Tunisia' might be found ?

Planes will need to be flexible on routing around the islands in future !

Drone footage released just there I see. Some really nice views of the lava flows.

Firing on all cylinders tonight. Anyone any idea how long this kind of low level volcanic activity can/will last?

See post #57! ;)

Mid-November would be "typical" although there's a reasonable chance it could be well into December before things calm down to a state of background noise.

Have been off-line-ish for the weekend and a bit before, and am surprised that no-one posted about the "lava tsunami" :x

It most definitely wasn't a tsunami (do these YouTubers know nothing? :roll: ) but it was quite amazing to watch. When I saw the first videos, I wasn't entirely sure it was real (or that it hadn't been sped up) but have since seen what I presume is validated footage and it's :o .

Here's a nice bit of drone footage, showing the four vents:


Google-translated description (apologies for the American spellings :x ):
In the drone shots, the 4 current emission centers are observed. Distributed and described from the Northwest to the Southeast.

The most Northwest, is at the lowest level and is the only one that emits lava flow.
The next is an emission center located at a higher level with intermittent strombolian activity
The third, at a higher altitude, which is the main lava source, has continuous strombolian activity.
The fourth and last to appear (located to the Southeast), it appeared three days ago with phreatomagmatic activity, it turned off on the 17th and has reappeared with strombolian activity on October 18.
