Earthquake swarm reported at Iceland’s Katla volcano
จับตาดูภูเขาไฟ Katla ที่ Iceland หลังจากรายงานพบการสั่นไหวถี่มากขึ้นรอบๆ
Posted on June 17, 2011
June 17, 2011 – ICELAND – Around 17:10 UTC an earthquake swarm did start in Katla volcano. This earthquake swarm is focused inside the Katla caldera at small point. The one earthquake that I have so far been able to record was a long period earthquake, but that suggests that this earthquake was created by magma movement. At current time I am not sure from where this earthquake did originate from. But from Goðabunga area in Katla volcano this types of earthquakes are common and no surprise at all. At current time I do not know what this means for Katla volcano. But so far no increase in harmonic tremor has been detected on the seismometers around Katla volcano. But that might not start at current time, as harmonic tremor is only going to increase when magma starts to move inside the Katla volcano, like did happen in Grímsfjall volcano few weeks ago. The location of this earthquake swarm strongly suggests that what is going on in Katla volcano is a dike intrusion in the Katla caldera. If that is powerful enough to start an eruption is a question remained unanswered at current time. Area of activity is marked by the earthquakes. Looks like a dike intrusion into Katla caldera. I am going to update or post new blog posts as this continues to develop. I do not think that these events are over. But it is hard to know for sure, since volcanoes are impossible to predict.
