Icelandic Isle rattled by multiple spasms of seismic tremors

June 21, 2011ICELAND – The tremors today have extended the entire length of the Mid-Atlantic Ridge rift that is running through Iceland. Seismic activity under the glaciers, which cover 11% of the land mass of Iceland. have been steady and consecutive for the last two weeks. On this map, we see new activity under Torfajökull (Icelandic for “Torfi’s glacier“) which is a rhyolitic stratovolcano and complex of subglacial volcanoes, located north of Mýrdalsjökull and south of Þórisvatn Lake, Iceland. Torfajökull last erupted in 1477 and consists of the largest area of silicic extrusive rocks in Iceland. More importantly, we see continuous seismic activity under Mýrdalsjökull, under which sits Katla, the volcano called the witch. The caldera of the volcano has a diameter of 10 km (6.2 mi) and the volcano erupts usually every 40–80 years. As the last eruption took place in 1918, scientists are monitoring the volcano very carefully as they believe an eruption of Katla is on the cards, particularly after the eruption of Eyjafjallajökull began in April 2010. Since 930, 16 eruptions have been documented. We may be on the verge of seeing more volcanic activity very soon in Iceland.  –The Extinction Protocol

    Small glacier flood from Mýrdalsjökull glacier (Katla volcano)
    Posted on July 21, 2011 by Jón Frímann
    During the night (and when I had unstable power) there was a small glacier flood from Mýrdalsjökull volcano. Some minor harmonic tremor change was detected following this glacier flood. This even was small one, many times smaller then what did happen on the 8 to 9 July 2011. Due to security concerns the Civil Emergency Authority did close the main road in Iceland for this area. Since they never know how big the flood can actually be. The main road was closed for about one hour. This glacier flood was detected around midnight 20 to 21 July 2011.

    This flood is actually so small it is hard to see it on the harmonic tremor plot from the SIL stations around Katla volcano.

    There never is any break this days.

    New harmonic tremor spike is currently taking place in Katla volcano. It was started with a ML0.8 earthquake at 16:56 UTC. I am going to post more information later on and earlier if this is something larger then small event.

    What great timing, reading your book and just finished “When Mountains Awaken” lots to digest and learn.

    Having read jons site for quite a like, and having checked the iceland meteorological site daily for over a year, the amount of earthquakes currently happening is nothing out of the ordinary

  5. Alvin,

    Where did you gather your statistics for the volcanic activity chart you have in The Extinction Protocol book? The best I’ve been able to find is http://www.volcano.si.edu/world/find_eruptions.cfm

    but those numbers don’t match up with your graph in the book, especially in 2010.

    Thanks
