Monday Eruption Update: Calm at Etna and Katla, evacuations at Lokon-Empung

Things are going to be getting a little hectic for me for the next few days as I get ready for my field/lab season in California (which starts Wednesday). I have just enough time to catch up on a few things that are happening/happened over the last few days.


Italy: Over the weekend, we saw a brief eruptive episode at Etna - you can check out some of the details on the Osservatio Etneo website (thanks to Dr. Boris Behncke). This new eruptive activity sent ash around parts of Sicily after intense fountaining (see top left) in the southeast crater. Be sure to check out some of the great video (with a strange article), from various sources along with some excellent images and a report from Etna via Volcano Discovery.

Iceland: We also saw a small jokulhlaup from Katla over the weekend that got a lot of people very worked up for sure. The unrest at the Icelandic volcano seems to have ended for the time being, but a close watch will be kept on Katla. The Icelandic Met Office has posted a brief summary of the flood that swept away a bridge at Múlakvísl and the Ring Road will likely be disrupted for months. However, the question of whether the flood was related to a very small eruption is still being explored (Icelandic). Be sure to check out the cool video of the flight over Katla after the jokulhlaup that shows the early stages of some of the 50-meter deep collapse structures (see below) that have appeared on the Mýrdalsjökull glacier.

Indonesia: This is not a good week to be in a country that starts with "I" if you don't like volcanoes (look out Iran). Last week we saw a small eruption at Soputan in Indonesia and today Indonesian officials placed Lokon (a twin volcano along with Empung) on highest alert for an impending eruption. A 3.5-km evacuation zone has been set up around the volcano to keep tourists and locals out of harm's way - but a stunning 28,000 people live within that exclusion zone. Lokon-Empung is only 20 km from the capitol of North Sulawesi, Manando. The volcano produced ~0.5 km / ~1600 foot ash plumes over the weekend and the volcano has been producing small plumes throughout most of 2011 so far in what were thought to be phreatic explosions. The last eruption at Lokon-Empung was in 2003 and the volcano has had several VEI 2-3 eruptions over the last 25 years.

  • Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.

Why I wear my life on my skin

For Damien Echols, tattoos are part of his existential armor.

Videos
  • In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
  • This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
  • Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
