Here are the results and answers to the last Friday Riddle.
An extra page was created for the answers of Name That Volcano(es) which can be found by clicking the link or you can search for it in the menu under Gems.
A hint from me, check the old Riddles frequently, you will notice certain patterns the riddlemasters use. This works especially with Alans and Suzies riddles. Name That Lava is a different story. Here you have a better chance if you ever were in this area and the landscape looks familiar. A tip here, even though i do not have the slightest clue when the next one of those will go in again. Looking for hints of vegetation can give you a decent hint in which region of the world the answer could lie.
RIDDLE – Name those Volcanoes # 9 went in on Ruminarian II – Tolbachik… Author GeoLurking December 7th.
The first was briefly the subject of a ‘blague Francaise’
The second used to have vents (now pits) that share their name with a footballing legend
The third is the only volcano within the arc of the SS islands chain to have erupted rhyolite pumice
The fourth is located approx. 3 kms due west of a small group of ’sibling’ rocks
The fifth shares its name with a species of lacertid
One point for each volcano and one point for spotting the link!

One of the correct answers to the seamounts we were looking for was Kick ’em Jenny. A submarine volcano which interests me ever since i first heard of it, when Erik Klemetti was looking for odd volcano names on his blog Eruptions more than 2 years ago.
So here comes a sum up on Kick ’em Jenny with links and whatever i could find on it on the internet.
Obviously the name refers to the rather harsh weather conditions which often occur in the sea above this seamount. And dont worry Kick ’em Jenny is not a lonely volcano, it does have more vents around and one of them is called Kick ’em Jack. It is a volcano which is caused by the Lesser Antilles Subduction Zone and watched because an eruption may cause tsunamis as it has happened before in 1939. On some old maps an island is shown in the region where the volcano is now situated. I could not find out if an old version of this volcano really was an island before, though it could not be totally impossible as long as the 2003 survey found an arc shaped collapse structure extending towards the west.
Kick -ém Jenny lies about 8km north of Grenada within the Lesser Antilles. It was discovered in 1939 when a spectacular eruption took place and Jenny broke the surface in a surtseyan style eruption. It is said to have thrown steam and debris up to a height of 275 m (902 ft). How this could be measured so exactly is beyond me. The eruption took place on 2 days, 23 and 24 of July in 1939. It was not the first eruption for sure, just the first which was observed. Ever since, the submarine volcano has erupted at least 12 times but this was only speculated due to seismic activity and it could not be watched from ships on the water. Kick -ém Jenny never stayed above seafloor or created an Island. At the moment its peak lies around 180 meters below the seasurface, where it has been in 1966 also. Mariners had been believing that the volcano had grown and was as close as almost 40 meters to sealevel but a research in 2003 could not confirm those expectations. Kick -ém Jenny is a very active volcano and ships should stay away from it in an exlusion zone of 1,5 km around the seamount.
The University of the west Indies has a page on ithe seamount and from there you can also find the detailed daily logs of an expedition of NOAA´s ship Ronald H. Brown which took place in March 2003 funded by NOAA. In those logs you can also check pictures of the ROV, sea fauna and even of samples which were taken during the survey and sampling 2003. On the main page there are also 2 sea beam images which will give you a better idea of the shape of Kick -ém Jenny, Kick -èm Jack and the surrounding vents.
When the volcano first broke the surface in 1939 several tsunamis have been created. The University of the West Indies created a chart list with a short description of the events since. The last eruptive event seems to have taken place in 2001. Geology Report of Kick´em Jenny
As long as this volcano is highly active and a rumbling can be heard sometimes, this might not be the last time you can find an post on it here. Maybe it surprises us with some action some time in the future.
This is a sum up done by me, a complete layman who just has a black belt in Google Fu and no expertise in vulcanology.

It is still the weekend and also a Sheepy Dalek post so let me ruminate about images on the blog a little.
This blog has a library of 3GB where we can store images to be shown on the pages itself. We are currently using 24% of the storage. As long as we are over a year old this may look as if we dont need much space, even though we have 188 posts here already, each of them adorned with pictures. We also harbour 37 pages, some of them even display my library of microscopic images. ( For people who have not already checked that… mostly SEM photos of different volcanic ash can be found in Gems. )
Still, if we are careless this storage is used up soon. GeoLurking discovered recently, if you upload an image again, after one ( in this case me) accidently deleted it, it goes in with the same title with the edition of -1. So even though it is no longer addressable it still counts. This also means, that when space becomes tight, the solution of deleting older images will not help.
So i am asking the dragon not to add audio files and keep a close eye on how much storage is still available. If you check the shopping cart one can buy 10GB of storage for 20$. That is a sum i can and will pay in case it is necesarry, if it is a one time payment and not a yearly sum.
So my thoughts on this. Lets still bring over images by our users, screenshots or something similar when they will expire because they are located on tinypics or if noone would see them because they were delivered in an email. If those images are really huge in size, could they please be worked on before we upload. Maybe add the images into the gallery we have ( did you know? ) within Gems so we can find them again. People who send images or upload them to Tinypic, could you please give the address of the cams or other sources where you took them from.
Iceland experiences a strong gale ( again!) but IngeB noticed a strange patter of earthquakes this morning.
I took a screenshot and here is IngeB´s comment again:
Has somebody had a look at Iceland quakes lately? If not all of them ghosts (rather bad quality with a lot of them), the actual picture shows a very clear pattern of the TFZ and its two main fracture zones, the Húsavík-Flatey-Fault in the southwest and the Grímsey-(Öxarfjördur-)Fault in the north: http://www.vedur.is/skjalftar-og-eldgos/jardskjalftar Compare eg. to p. 2 here: http://www.sciencedirect.com/science/article/pii/S0025322701001724
