Something strange is happening at Yellowstone!

Strange signals from the Yellowstone caldera. The ancient volcano wants to get back alive?

Something strange is happening at Yellowstone! Or, something strange is happening to the tools that monitor the seismic activity of the volcano more dangerous than the entire planet. Looking at the data of the ' observatory Norris Junction shows something very strange. Starting at 18:00 on 28 November 2012, the seismic recordings seem like crazy and completely out of scale (see below). Currently (December 2, 2012), the readings are not yet back to normal, but they mark particularly intense seismic activity.

What is happening to the Yellowstone Caldera ? The volcano wants to return to wake up? Or it is a simple malfunction of the instruments? Below, you can see the image of the seismic activity of the November 28, 2012, until 18:00 that seemed normal, until I started reading these "crazy". [ See original data ].

At the time of writing this post, the situation does not seem to change. In the following days, November 29 , November 30 and December 1

the data is still out of range. Following the reading of 1 December. What is happening in Yellowstone? Looking in the network, there appears to be still no official explanation of the anomalies recorded in the seismic data of the caldera. The first hypothesis we could calm our hearts is that it is a malfunction of seismographs. The second hypothesis, much more disturbing, is that the volcano, after a long period of 74,000 years, has decided to resume its activities.

The volcano is located under the Yellowstone National Park is about 70 km long, 30 km wide and is located 8 km deep beneath the earth's crust, potentially one of the largest volcanoes in the world. Since 2004 the level of the magma rose to a record pace of six centimeters per year and experts fear the possibility of an eruption, the third in the last 2.1 million years. Between 2007 and 2010, the volcano seems to have remained stalled, but overall the ground around the volcano has risen by about 25 cm. "This is a remarkable observation, especially in such a vast area," said Bob Smith , a professor of geology at the ' University of Utah . The lack of reliable data prevents to determine whether and what a certain period of risk: the fact is that in the case of an explosive eruption that would be a thousand times more powerful than the Mount St Helens and the potential to make uninhabitable two thirds the United States. Millions of people remain homeless, toxic fumes contaminate crops and water sources.
