Gases released as a result of Siberian magmatism could have caused environmental damage. For example, perhaps sulfur particles in the atmosphere reflected the sun’s heat back into space, cooling the planet; or maybe chlorine and other chemically similar nonmetal elements called halogens significantly damaged the ozone layer in the stratosphere. $$$$$ - Research / Volcanoes and extinction scenarios (2) Scientists have uncovered a lot about the Earth’s greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system. “No one had ever looked to see if mercury was a potential culprit. This was a time of the greatest volcanic activity in Earth’s history and we know today that the largest source of mercury comes from volcanic eruptions,” says Dr. Steve Grasby, co-author of a paper published this month in the journal Geology. “We estimate that the mercury released then could have been up to 30 times greater than today’s volcanic activity, making the event truly catastrophic.” Grasby is a research scientist at Natural Resources Canada and an adjunct professor at the University of Calgary. $$$$$ [link to earthquake-report.com] |

| Luisport User ID: 8769797 01/13/2012 08:18 AM ![]() Report Abusive Post Report Copyright Violation | Minor earthquakes in Hekla volcano system Posted on January 13, 2012 by Jón Frímann During the past 24 to 48 hours there has been some unusual and interesting earthquake activity in south part of Hekla volcano system. I am unsure on what this means, as normally Hekla volcano does not have any earthquakes before an eruption. However, that is not the only type Hekla volcano can and has erupted over the centuries. One of the aspect of Hekla volcano eruptions is that it can and has erupted in fissure eruptions outside the main mountain. This type of eruptions can last from few week and up to almost a year. Based on the limited historical records of such events. This type of events are always basaltic lava events that do not make a lot of volcano ash when they start. There are clues that Hekla volcano might be about to have an fissure eruption some time in the future. But when and where is impossible to know for sure at current time. How that is going to manifest it self when the time comes is also impossible to know for sure. At current time there is however no eruption starting in Hekla volcano. When it might start is an good guess, with no answer to it. [link to www.jonfr.com] |
| Luisport User ID: 8769797 01/13/2012 12:31 PM ![]() Report Abusive Post Report Copyright Violation | New earthquake activity in Upptyppingar tuff mountains Quoting: Luisport Posted on January 7, 2012 by Jón Frímann During last week and on 5. January 2012 there where few earthquakes in the Upptyppingar tuff mountains. This mountains are not volcano by definition (yet anyway). But since the year 2007 there has been magma intrusion into that area. This magma intrusion however stopped and has been stopped for several years now. But that might be about to change. As on 5 January 2012 there where few small earthquakes with the depth of 12 km. Last eruption that took place in the Upptyppingar tuff mountain area where about 12.000 years ago, around the end of the last ice age. Considerable deformation has taken place in the crust in Upptyppingar tuff mountain since magma started to build up there. Current earthquake activity in Upptyppingar tuff mountain is not high at the moment however. But it has remained rather constant for the past 7 to 10 weeks at least. But due to lack of SIL stations in the area, it is hard to know how many earthquakes have exactly been taking place there at the moment. Upptyppingar tuff mountains are part of Kverkfjöll volcano system. This new magma into Upptyppingar tuff mountains suggests that Kverkfjöll volcano might be about to enter an new time of activity. But they have been dormant since the year 1968 at least. But Kverkfjöll volcano have also been seeing some earthquake activity on its own. It is most likely is the case that we are going to see eruption taking place in Upptyppingar tuff mountain one day. But the wait for it might be long however.

| Luisport User ID: 8769797 01/13/2012 02:11 PM ![]() Report Abusive Post Report Copyright Violation | Minor magma dike intrusion into Upptyppingar tuff mountain Posted on January 13, 2012 by Jón Frímann Yesterday (12.01.2012) there was an minor earthquake swarm in Upptyppingar tuff mountain. But they are inside Kverkfjöll volcano fissure swarm that extends several km away from the main volcano. The largest earthquake in this earthquake swarm was around ML2.0 in size, with the depth of 14.4 km. But this was also the deepest earthquake in this earthquake swarm. But most of the earthquakes had the depth of 14.4 km and up to 7.8 km. So I am sure that this was magma, rather then tectonic movements that did create this small earthquake swarm. This might mean that there is more activity on the way in Upptyppingar tuff mountain. As this suggests that new magma has started to flow into the magma sill that has formed under the Upptyppingar tuff mountains. It is hard to know or if there is going to be an eruption there. But I find it most likely going to be the case. But it might well be good 10 to 20 years into the future until an eruption happens in that spot. But activity started in this area in the year 2007, so there already have been good 5 years since activity started in Upptyppingar tuff mountain. For the moment however, it is all wait and see and earthquakes. [link to www.jonfr.com] |

| Luisport User ID: 9856549 01/30/2012 08:07 AM ![]() Report Abusive Post Report Copyright Violation | Earthquake swarm in Katla volcano caldera Posted on January 30, 2012 by Jón Frímann This morning there was an earthquake swarm in Katla volcano. This is the first earthquake swarm of the year 2012. This earthquake swarm is most likely created by an dike intrusion. Based on how dense the earthquake swarm appears to be. But that is often an sign of an dike intrusion in an volcano. How this earthquake swarm is going to evolve over the next few hours impossible to know for sure. That depends on what the magma is going to do that is creating this earthquake swarm. The earthquakes can be seen on my geophone web page here (English). The geophone at Skeiðflöt is going to go up this week. So all activity in Katla volcano is going to appear more clearly following that. Sadly. No high resolution of the earthquakes that take place is not going to be available until I move back to Denmark. As my main earthquake computer is offline and is going to be so until that time. I am going to post updates to this if anything more happens. But it might take a while as I am travelling today to Reykjavík area and tomorrow I am going to Skeiðflöt tomorrow.
