Reawakening? Chile’s Chaitén volcano shaken by earthquake swarm of 80 tremors

In 2008, as seen here, Chile’s Chaitén volcano erupted after being dormant for more than 9,000 years. The eruption was the most powerful to occur on the planet in the last decade.
November 22, 2013 CHILEIncreased seismic activity has been detected under the volcano, Chilean scientists reported. The devastating Plinian eruption of Chaitén in May 2008 forced the evacuation of the entire population of the small coastal town of Chaitén, located only a few kilometers south of the volcano. After the initial explosive phase, several lava domes have been growing slowly by extrusion of degassed, viscous magma. This phase ended in 2011 and since then, the volcano has only produced degassing. On 20 Nov at 08:07 (local time), a volcano-tectonic magnitude 2.4 earthquake occurred at 6 km depth north-east of the volcano. It was followed by a swarm of more than 80 quakes of mostly long-period type, characteristic for movements of fluids (gasses, water, and possibly magma) inside cracks inside the volcanic edifice. They are considered potential precursors to eruptive activity. In addition, pulses of volcanic tremor and a second volcanic-tectonic quakes of magnitude 2.7 at 11:39 local time, this time at shallow 4.4 km depth were recorded. –Volcano Discovery

    Presently, in the news, the flop of The Affordable Care Act, otherwise known as Obombacare and now The Nuclear Option, just voted by the Senate hindering The Republican ability to filibuster. Probably an attempt to draw The Country’s attention away from the disastrous healthcare wealth distribution.

    Well, I believe that another headline grabber is just around the corner and we are seeing it unfold here. It is interesting how many sleeping volcanoes are awaking……

      Thank you Dennis E. Interesting thought there, almost like a false flag, but I don’t think they know (or want to know) what’s going on beneath their feet. Have you noticed all the earthquake swarms lately? Earlier today it was in the Iran/Iraq area and now I see one in China. Then we can’t forget Indonesia and Japan. Kind of creepy I think.

      I have been watching Chaiten since the initial eruption back in 2008.
      There is a webcam.
      Officially the eruption phase is over, however the webcam shows many days of significant steaming.

      My money is on Sinabung.(Sumatera Indonesia) The eruptions at Sinabung are getting progressively larger. This is an unstudied volcano. It’s been officially dormant for many years. Indonesia is a country with many other active volcanos that require careful monitoring. Sinabung had no priority – until relatively recently.

    ‘Chile’s Chaitén volcano erupted after being dormant for more than 9,000 years’; I wonder how many more of these so called dormant Holocene volcanoes may in fact have just been having a siesta? In geological terms 10,000 years is not even a rounding error.

    The end times are approaching. Be ready.
