oh yeah, that's a goody. It's on my shelf too. 

Note to self: always go and visit distant rellies when a volcano is about to blow.

The magma from this is coming from a deep source (17 km) which is well below the crust and basically straight from the mantle, which is kind of astonishing for the first flush of an eruption (normally you eruptions pick up pockets of melt along the way or inject into an existing magma lens in the crust before erupting).

There's some pretty cool live video going on right now from Etna.  The main crater is jetting up to 800m, chucking lava bombs every which way and a satellite crater has opened up at the foot of the cone.
(edit: reports of them hitting 2000m.{#Eek}

For those of you not aware of the terror of a nuée ardente (also known as pyroclastic flow). They are a ground-hugging, high-speed mass of extremely hot pulverized volcanic rock and gas formed when the eruptive column, shooting up into the sky collapses under its own weight. You can see the volcano to the right of the image. The pyroclastic flow is shooting down its left slope, likely in excess of 100 mph (160 kph). The hot ash and rock mass is racing down on a cushion of trapped gas, sort of like an air hockey puck. Pyroclastic flows level everything in their paths. 
 
The great Frank A. Perret, self-trained volcanologist, had an observation hut on a ridge at Mount Pelée when a pyroclastic flow came down towards him. He ran into the hut and dove under a table. The ridge diverted the main part of the flow but he described his lungs instantly starting to burn from the superheated gases and the ash cloud. Luckily he survived pretty much unscathed. I read all his monographs as a teenager.

 
oh, cool. more reading. Thanks.

Iceland authorities have put out a warning for the Reykjanes peninsula about a teeny eeeny bitsy witsy eruption that is expected to start in a couple of hours. Might close the airport temporarily but otherwise no major risk expected.

nice one Richard. {#Cheers}

Just for scale, what we are seeing is about 700 meters from the crater to the top of the screen. Some pulses go way beyond the top of the screen but a lot of it is clouded in ash.

Cool.
I like the comments saying it's fake too... apparently it looks similar to yesterday's activity. 
 
Well, they are not entirely wrong (although it is not fake). The periodicity of it is astounding
