100th post

I’ve hit the 100th post mark on Eruptions, which isn’t too bad for a few months on the blog.
If anyone has any suggestions of what they would like to see more of, less of, or any other changes/suggestions, drop me an email or leave a comment. I’m still fleshing out exactly what this could be, so any input would be appreciated.
Otherwise, enjoy the volcanoes!

  1. Love your blog, please don’t go on holidays alot and can we have more information on the welfare of the native animals eg the loro barranquero near volcan de Llaima. Is it extinct? Have also read that there are wild canary flocks( escaped pets) on a Hawaiian Island. Did they die? And what about the penguins near Alaskas volcanoes?

  2. Calderas, Calderas, Calderas. Any volcano that may impact world climate.
    Looking back into history, scientists are finding more and more that volcanoes effect climates and disrupt growing seasons around the world.
    I want to know what is happening with Rabaul and other simmering Calderas. I’d like to know about earthquakes that may serve to destabilize or reawaken volcanic systems. So when strings of earthquakes happen in a particular area of the world … I’d like to know if there will be a possible volcanic result.
    I’ve got a lot to learn … but I guess we all do as we have not yet learned much about Caldera volcanoes.
    Rafael Peralta had some interesting thoughts. I’d like to know some of the speculations about what drives volcanic activity.
    Also, I can’t afford to subscribe to professional publications. If you can sometimes give a short summary of anything in these publications that pertain to predicting and understanding caldera eruptions. I’d greatly appreciate it.
    Now, there are also other areas in Chile that are also having a bunch of earthquakes now.
    For example near the Bolivia, Chile and Argentine border there has been a lot of activity as of late. A few more earthquakes in the four range have occurred in the past few days.
    This article linked to in this professional journal below has information on an inflation at the Lazufre volcanic region.
    They write in the abstract to the article,
    “The deformation signal shows an uplift of up to ~ 3 cm yr− 1 during 2003–2006, affecting an area of about 1100 km2, comparable in size to super-volcanoes such as Yellowstone or Long Valley. This deformation signal can be explained by an inflating magma body at about 10 km depth, expanding and propagating laterally at a velocity of up to 4 km per year. Although it is not clear whether this intrusion will lead to an eruption, its dimensions and the rapid deformation rate insinuate that a potentially large volcanic system is forming.”
    If as Rafael Peralta suggested there is some geological process taking place in Chile that is larger than just a localized event in the Chaiten region – there may be more large volcanic eruptions to follow.
    Note a few months ago I was looking at dates of eruptions in the Smithsonian chart of large volcanic eruptions. There was some possible clustering of large caldera eruptions in Kamchatka. A lot seemed to have there happened around 42,000-40,000 years ago.
    Your website is great Erik!
    These are the things that interest me. Several people at work often watch shows like “Naked Science” and see specials that deal with super-volcanoes. I didn’t know about them until a couple of years ago.
    I am not too concerned about Long Valley, Yellowstone or Toba erupting in my lifetime. However, there are so many caldera volcanoes somewhere between Chaiten size and Yellowstone size. I think we are due for a midsize eruption. Krakatua or Tambora in the 1800’s. An even earlier eruption of Krakatau is thought to have blown open the strait between Sumatra and Java by making a Caldera between them. Apparently there are some legends that they were once connected.
    So because I now know that volcanoes around the world can impact me and many others – I am much more interested in them.
    I don’t mind coverage of smaller volcanoes … but I only pay a lot of attention to the ones that have the potential to change the weather of the world.
    Keep up the good work – no matter what direction you take you take your fine blog in.
