…to our new volcano blog (02/2015). We hope that this blog on and about all volcano related matters will become a meeting point for volcano lovers – a place to learn and ponder, for questions and answers, for new information and reviews, for science and speculation – in short, a place to relax and enjoy.


Two years ago we have started out as a group of 11 enthusiasts but, as such things go, our number dwindled to two over time. So here are Granyia and Agimarc, doing their best to bring you some interesting stuff and news on volcanoes all over the world. We hope you enjoy our posts, but don’t just stop at the end – scroll down to the comments section where we are leaving any updates on present volcanic activity, links to new interesting papers or other bits of news from the volcano world. Of course we also love to see you commenting there, and if you ever feel like writing about a volcano-related matter yourself, we invite you to do a guest post.




A word about the authors

We, Agimarc and Granyia, have been deeply interested in volcano matters for many years. We have read up on every volcano showing new activity, on its geologic settings, tectonics and history. We have taken online lessons, read papers and followed bulletins on official volcano related sites. We have gathered quite a bit of knowledge but – we have to emphasize this – we are no professionals in the field. Here is our disclaimer that goes for every post on this blog:

“Disclaimer: We are no scientists, all information in our posts is gleaned from the www and/or from books we have read, so hopefully from people who do get things right! 🙂 If you find something not quite right, or if you can add some more interesting stuff, please leave a comment.”

  1. Hello and thank you to Spica et al.!
    Because I am neither a fan nor a member of the requisite social media groups, I found myself unable to comment anymore in the Café. So I welcome the new more open forum, appreciate your combined efforts and knowledge, and send my best wishes that this blog may live long and prosper!


    • As you see it is a team effort of 11 people so far. TEAM and TEAM WORK is the very important term here!
      Thanks for the well wishes. You found the about though it is not linked from the menu a.t.m. 😉 ( That will change as soon as the next post goes in.
      Not a social media fan myself.


  2. I’m wondering if anyone else feels like something big is going on under Mt.Herdubreid in Iceland. Seems like a lot of activity going on there. Any chance of it becoming active or erupting after so long a time?
    Thank You

    • Seems it has calmed down now. Thanks for the links that was very helpful to understand what’s going on and that there isn’t much to worry about.
      Thanks again and Cheers to you.


  3. Hello!
    This is Alan C (as was found ‘elsewhere’)
    I have only just found your site and hope your numbers grow!
    The webcam list is very helpful.

    If you wouldn’t object, perhaps I could occasionally post the odd comment?

    I can be contacted via the email

  4. Hola, soy de Chile, de la región de Antofagasta y he leido el artículo sobre el volcán Ollagüe y me ha interesado mucho, soy fotógrafo y he registrado el paisaje de la comuna de Ollagüe fotografiando los volcanes de San Pedro y San Pablo, el monogenético La Poruña, el monogenético La Poruñita, el volcán Ollagüe, el Aucanquilcha y otros. Solo les quería enviar un saludo y agradecerles la información que aparece en su blog, Si alguien desea información visual o guía para llegar a estos volcanes solo me avisa.


    • Hi Sergio, thank you for your greetings and your kind words! Do you have your volcano photos on a website? You could leave a link, if you like. I may put it in our side bar.


  5. Hi… came here via your entry from Oct /16 about Comoros. While I certainly don’t understand all of the terms and the detailed science, I found the article interesting. I check the USGS earthquake map several times a day (an obsession? maybe!) I’d noticed many earthquakes occurring at Mayotte for about the past month or so. I looked it up a while ago and read a bit about it. I might even have seen your post then…can’t remember. Anyway, I was posting elsewhere about the Hawaiian eruption (talk about an obsession….it’s fascinating) and wanted to mention the Mayotte situation, so I was back on Google to get more info and thus read your entry. I plan to see what else I can find about the current earthquakes in Mayotte. I actually live in a very inactive part of the world: the province of Saskatchewan, Canada. There are the occasional quakes having to do with potash deposits and underground erosion, although none have been near me. I’d have to read up on this again…I’m rather forgetful. LOL Anyway, thank you for all your effort and info. I’ve bookmarked this page.


    • Hi Roberta, I’m glad you like it here, thanks a lot! I have tried to find out myself, but there seems to be no explanation as to what exactly causes that EQ swarm near Mayotte. It goes on since 10 May already. The BRGM (French geol. agency) just say vaguely that “quakes likely are the result of seismic hot spot (Comores) as well as the island’s position along the East African rift.” I read that a team of geologists from France has travelled there last week to look into the matter, but so far have seen nothing about results. I guess they might get published later on this website, which so far has the daily updates on numbers of EQs:

  6. I love your website! You would be remiss if you don’t mention Darryl G. Lloyd’s website on Mount Adams, Washington: http://www.mtadamsbook.com/ . His splendid, beautifully-illustrated book, “Ever Wild: A Lifetime on Mount Adams” can be ordered/purchased directly from him (longshadow@gorge.net).


  7. SInce there was NOT a volcanic eruption reported on Simushir in 1994 and since the earthquake clusters for 1994 and 1995 were well to the south, could the apparently hasty evacuation of Kraternyy submarine base have been due to some sort of nuclear accident with a missile or a submarine reactor? Is it known or even rumored where everyone went? peterfzoll@yahoo.com


  8. Hi my volcanologist!!!
    I’m Igor Collins and a Young volcanologist….
    Please let me know if there is any software that we can use to make picture relative to volcanology other than “Microsoft Paint”


  9. Bromo is said to be a tephra cone and the active vent of the Tengger caldera. Is there a good aerial photo of the summit of the entire edifice and the older craters which the active vent is part of?
