Etna had paroxysm # 12 for this year on Saturday and Dr. Boris Behncke announced it in advance and provided an image and explanations as always. http://www.flickr.com/photos/etnaboris/8665430880/in/photostream I especially like his vivid decriptions of the situation.
IngeB: “Loud bangs were still to be heard yesterday evening and ash fall continued in some regions ( http://www.meteoweb.eu/2013/04/etna-ancora-boati-dal-vulcano-colonna-di-fumo-e-debole-pioggia-di-cenere-sul-versante-orientale-foto/198775/).
Lava columns reached 800 m today (http://www.meteoweb.eu/2013/04/violentissima-eruzione-delletna-nube-di-cenere-verso-reggio-calabria-le-immagini-in-diretta/198966/ ). Volcanic material (lapilli, I suppose, hope not bombs) rained down on western side of the volcano.”
Black rain from the ash cloud and the distant roar of Etna:
Some points from an interview with D. Patanè (INGV):
– very important eruption, about 20-30% more energetic than the last ones
– eruption column up to 10.000 m height
– very fast intensification of eruption
– lava flows til down to bottom of Valle del Bove (I think that is what is still ongoing and seen on the webcams eg. http://www.lave-volcans.eu/webcams_etna.php?numero=2 )
– second paroxysm within 48 hours.
On this footage you can watch the shower of lappili falling over Etna’s surrounding cities:

I never like it when i have to report of such desasterous events. *sigh*
Islander provided a map i had not seen before.

And last but not least:
I had my normal link problems during weekends and sent Chryphia the wrong ( old ) last weeks riddle by AlanC.. So you get a riddle on a Sunday for a change!
It’s sad, but because he can’t wear me, poor old Uisdean has to stand by the table naked!
What is my name?
What am I and of what am I made?
