Ruapehu or Mount Ruapehu in NZ has two large skiing areas.
GeoLurking pointed to interesting activity at New Zealands Ruapehu volcano.
You can view this for yourself on GeoNet Ruapehu
http://www.geonet.org.nz/volcano/activity/ruapehu/
Or directly at http://www.geonet.org.nz/images/volcano/drums/ch/fwvz/10/drum.png but the drums seem to have stopped for the moment.
More info on this volcano is found on the GVP site Ruapehu
Here are 2 webcams: one also to be seen on the GeoNet link above and two.
And the Wikipedia article on Ruapehu.
Japani´s Sakurajima exploded again yesterday.
This is an older satellite image from LandSat
KarenZ found an interesting Video.
And i found this one, though i am not sure from which day this is.
Here are the webcams i know of: One . Two Three and Four:
Erik Klemetti did an update on Sakurajima on his blog Eruptions.
The GVP information and the Wikipedia article on Sakurajima.
And to end this post 2 images of Hekla from the Milacam
In a storm on the 21 of July
And in te morning glory on July 26th.
Have a nice sunday
Spica
Hook Head in County Wexford?
Isle of May?
One time i want to shout Ding too, so DING. Now about the rocks??
@ Spica, Talla was first at 16:56 on the previous page.
But maybe we can give 1 point to both Lisa and Talla, since the new-comment start probably made the thing confusing?
I mean, one point to each (that above was a confusing sentence)?
I think Talla got it, but here is one more first lighthouse location: Valahnúkur, Reykjanes, Iceland.
And..Nólsoy, the first lighthouse on Faroe islands.
Stongin peninsula.
Westman Island Archipeligo: Heimaey or Ellidaey, Iceland
Volcano, Vestmannaeyjar volcanic system
Lava: basalt
So now we have the location, still missing the rock though. One more point to go for lava type and volcanic formation…
Wikipedia: “fine grained basalt of a dark-grey colour with tinges of green and greenstone.”[
Sadly, wikipedia is wrong on this one, so no.
(at least according to BGS it is wrong, just so it’s not just me saying this…)
“The Isle of May is part of a sill of teschenite – a rock much like dolerite.”
Source: http://www.geowalks.co.uk/eso/StMonansTeachersGuideHigher-v4.pdf
Ding Dong, it is teschenite, also known as amalcime gabbro.
And the volcanic formation is a sill. So one point to Sissel.
Are we very PC nowadays? I thought it analcime gabbro…
All I can find for the Isle of May is “fine-grained basalt”. Thanks for the point for the island!
Yep, that’s what wikipedia and similar pages say, but it’s actually not…
@ Sissel: An Olympian type dead heat – you put in more information though! (If we have the right answer that is!)
eehhhh… dead heat, what does it mean?
BTW, you were great!
A dead heat in racing means crossing the line at exactly the same time! I’ve no idea why we say this in British English. I think it’s the same in American English. I’ll have to look it up! (You were very good too!)
Aha, now I understand! My English is really improving thanks to the members of this blog.
There is another – still small quakes series starting at Krísuvík, southwest Iceland: http://www.vedur.is/skjalftar-og-eldgos/jardskjalftar/reykjanesskagi/#view=table
And there is talk about a lot of dead fish which have been found by a diver in nearby Kleifarvatn (lake). Though a lot of changes in the environment of the lake have been taking place after the big quake of 2000, no scientific research has been done there up to now following a biologist. http://www.visir.is/fiskar-i-kleifarvatni-sagdir-drepast-i-storum-stil/article/2012120729453
Basalt and greenshist, no idea of volcanic system (keeps on googling….)
No, it’s not basalt (see above). And to make it clear, I am not asking about the name of volcanic system, just the type of volcanic formation…
Oh then it must be porphyritic felsite, volcanic breccias and tuffs, and it’s an ancient magma chamber, like on rum island?
and no i have no idea what im talking about
phonolitic trachyte for the lava? Colonnade or entablure for the formation?
Oh oh oh!
I found this information: “The island is composed entirely of a volcanic greenstone or olivine-dolerite sill”
From “The Story of the Isle of May National Nature Reserve”, http://www.snh.org.uk/pdfs/publications/nnr/The_Story_of_the_Isle_of_May_National_Nature_Reserve.pdf
Another document mention that the greenstone is teschenite.
Yes, this is it!
But Sissel was 1 min faster (see above).
I noticed. Beaten by one single minute! *sigh*
Ursula: The draft for the post is in. Maybe add the winner of the las point and publish. I got to serve dinner now. Zuchini creme soup, steaks with baked potatoes and 2 sauces and a special blueberry cake.
@Spica: will do in a moment (and you are making me hungry
), but just to summarise the points, here are the winners:
Inge B – 1 point for puffins
Sissel – 1 point for grey seals and 1 point for teschenite sill
Talla & Lisa – 1 point each for Isle of May
Congratulations and thanks for a good “race” everyone. I hope you had fun guessing.
Thanks, yes, liked it a lot.
It was really fun, exciting! And surprising, that the rock was not basalt. So many locations were in the race, I have read so much today! Even about Puffin breeding places and first lighthouses. Thank you very much, Ursula. And congratulations to all pointwinners!
Really fun, thank you!
Spica, what a great puffin video!!!
Was posted before here, i think by Diana.
Thank you all for the point! I do love looking around the world for places! It’s such a great way to learn about geology (and everything else imaginable). Well done to Inge B, Sissel and Lisa!
Sniffle… Sigh…
You know, that sounds like a killer one, Mohr im Hemd as dessert after the blueberry cake?
No Mohr im Hemd today. My oldest was here with her bf, She has the recipe ( and the form) and can do it herself whenever she likes.
Ah, I must though admit that I hope to one day taste the Mohr im Hemd…
I am a terrible sweet tooth.
New post is up!
Hmmm, deep 3.5 right underneath Kohala volcano on the Big Island of Hawaii.

At 12+ km down… that’s going to be in the feed system. To give you an idea of how that is organized… and old plot.
I totally missed the Name that lava competition. I was out of action yesterday….. some sort of bug that kept sending me to sleep and making joints hurt.. A bit better today but I will not go far. I have much work to do on my PC so I will be in and out annoying people today.
Congratulations to the winners.
