After a week of following the magmatic emplacement out by Eyjafjarðar at Gjögurtá in Iceland it seems like the activity is slowly diminishing. One should though remember that the activity can resume at any given moment, and that the magma probably will continue to propagate upwards over the next couple of years even if no new magma is introduced into the system.
During the last couple of days we have learned that the area most likely has had a shallow magmatic emplacement during the last 10 000 years, this is evidenced by the unique fresh water hydrothermal vents. These vents have created a unique environment in the Antarctic Ocean, and if an eruption occurred that micro-environment would be lost forever.
Nautilus at Kick’Em Jenny
During the weekend Nautilus and Dr. Robert Ballard will reach the end of the Journey, they will among other things investigate the volcanoes of Kick’Em Jenny and Kick’Em Jack in the Lesser Antilles. Nautilus is a Remote Operated Vehicle (ROV) exploring the ocean floor. I suspect that this will be the staple diet cam-food for the weekend, so let us make it official.
Kick’Em Jenny is as you know one of the more enigmatic volcanoes in the West Indies, and having a good look at her has long been on my list of things to do. Thanks to the Nautilus campaign I get to do it from home.
Where I live it is the National Cinnamon Bun Day, and I am making the best out of that. Try some with the weekly volcanic riddles.
As usual, two points will be awarded if you solve the riddle before I append the clues, 1 point with clues.

Best of luck and have a very merry Weekend!
This is five minutes from start of a pyroclastic flow from Sakurajima untill it reaches the shoreline. The ash column hit hard winds and a rainfront and emediately collapsed into a columnal base surge/pyroclastic flow. The ash flowed the entire way to the shoreline in less than 4 minutes. If anyone was there they are dead now. I am posting the entire sequence up untill it hits the water. The images comes from this cam:
Images are from minute 0 with the max columnal height before breaking at ends as it hits the beach.
