Earthquakes between Bárðarbunga and Grímsfjall volcanoes
Posted on July 5, 2016 by Jón Frímann

Today (05-July-2016) at 05:56 UTC an magnitude 3,4 earthquake took place between Bárðarbunga and Grímsfjall volcanoes.

This earthquake suggests that an complication is on the way. The question here is if an interaction between Bárðarbunga volcano and Grímsfjall volcano is on the way. Since both volcanoes are preparing for an eruption. [Speculation!] All that I get from my models (in my mind, since I don’t have the computer power or the skills to make them PC friendly at the moment) is confusion. At worst a magma dyke from either Bárðarbunga volcano might enter Grímsfjall volcano or an dyke might come from Grímsfjall and enter Bárðarbunga volcano (hint: A result of either of such event is rather catastrophic eruption, even if just for a short time). What can also happen is nothing, just earthquakes and nothing more. However, increase in the earthquake activity at this location suggests that no such luck is on the way. When and if such event happens is impossible to know, what can be done is to keep monitoring, day and night. This is going to happen the when and the way it wants to happen, all that can be done as humans is to wait and see. [/Speculation!]

Someone is posting a thread about an eruption righ now. Said police were shoveling ash off of roofs?

Is this what anonymous was talking about

He was talking about one eruption in Iceland... not south america.

Current status of Hekla volcano

Three main parameters are monitored by IMO: seismicity, surface deformation, and gas emissions. Figure 3 shows an almost constant rate of the number of detected earthquakes and the cumulative seismic moment during the last 3.5 years.

Hekla 20160707-3 Figure 3. Overview of seismicity at Hekla from January 2013 to early July 2016. Both the cumulative number of earthquakes and the cumulative seismic moment show a near-constant trend, reflecting background conditions at the volcano.

The most recent deformation measurements made by colleagues from the University of Iceland and the University of Gothenburg (mostly lead by Prof. Erik Sturkell, Prof. Páll Einarsson, Ásta Rut Hjartardóttir and Halldór Ólafsson) are shown in Figure. 4. The plot shows the east component of tilt measurements made at Næfurholt, which has been representative of Hekla´s inflation/deflation eruption cycles since 1985. The trend interpreted as inflation shows a broadly constant, long-term trend signal 2000. The 2000 eruption level was exceeded sometime between 2007 and 2009.

Hekla 20160707-4 Figure 4. Overview of changes in tilt at Hekla as measured at a site in Næfurholt. The plot covers the period since 1985 and it includes the last two eruptions (represented by a sudden deflation of the edifice). Changes in tilt at Næfurholt have been interpreted as signs of steady inflation since 2000, and have now significantly overpassed the level before the 2000 eruption.

Gas measurements made at Rauðaskál using DOAS have seen no detectable concentrations of SO2 emitted by Hekla since measurements began in 2014. The detection of SO2 is anticipated to be a signal of magma moving closer to the surface.

Conclusion and recommendations

Since the 2000 eruption of Hekla, significant improvements have been made to IMO's monitoring networks around the volcano. It is hoped that these networks will, collectively, allow for a timely eruption warning, allowing steps to be taken to mitigate the impact of the eruption. However, due to harsh environmental conditions around Hekla, together with the potential for data-transfer and handling problems, a definite, short-term forecast cannot be guaranteed. Although unlikely, the next eruption of Hekla could occur with little or no forewarning, despite having all monitoring and warning systems fully functional. For sightseers on and around Hekla, the potential for explosive volcanism must be kept in mind. At close-range, an eruption of Hekla would produce a variety of lethal hazards, including incandescent (pyroclastic) flows of lava fragments, ash and gas. Taking into account IMO's improved monitoring capabilities, and based on the behaviour of Hekla in 1991 and 2000, the unpredictability of the volcano is such that the warning-time under optimal conditions could be less than an hour.

Interesting tweet from Ben Edwards, a volcanologist.

EQ lights..eruption lights??

Yikes!


According to this article, earthquake lights are more likely to happen near rifts.

KATLA ON VERGE OF ERUPTION???

[link to en.vedur.is]

Quakes continue At KATLA

[link to en.vedur.is]

Katla is stirring but one never knows what she's up to since she has a tendancy to misbehave in July.

According to local news she is being closely monitored these days.

Small glacier flood from Mýrdalsjökull glacier
Posted on July 11, 2016 by Jón Frímann

A small glacier flood started from Mýrdalsjökull glacier few days ago. The most risk is from sulphur gases and other gases from the glacier flood that might be concentrated in lower areas. There is also a minor risk of the flood destroying walking path bridges in the area it goes over. This glacier flood might go into Emstruá river and there is the risk of destroying walking path bridges in the area. No other risk is expected from this minor glacier flood from Mýrdalsjökull glacier. This is a normal summer release of hydrothermal water from the glacier. Happens every other year and sometimes every year.

Three earthquakes shook sharper Mýrdalsjökull
 07/14/2016 - 03:12
 

Three massive earthquake, the biggest of 3.6 magnitude, occurred in the south of the Katla caldera under Mýrdalsjökull the twelfth time last night. The other two were also at or above 3 magnitude. Cycle smaller tremors followed. Hulda Rós Helgadóttir, an expert in natural hazards at the Icelandic Meteorological Office, said cycle have died down by half in one night and all been quiet since. In an interview with news agency said that Latent Mýrdalsjökull would have been more active recently.
Small gel was recently fired Aglientu glacier, which goes from Myrdal Glacier northwest, and ran geothermal water into the Forex Emstruá and thereafter Markarfljót. It is believed that the race began on July 7, and it is only now that return is beginning to decline in the river, said Hulda.

"This was not a big leap, the sulfur smell came about when she started to feel soon after," said Hulda, "and this was accompanied by slightly elevated conductivity." She says too early to say, however, whether, and what can be read out the rally last night, first need to consider your data. "But we closely monitor developments and shifts rivers ahead Mýrdalsjökull," said Hulda.

* Updated at. 10:23.
The earthquakes that were recorded in Katla last night were not as strong as was thought at first. The strongest earthquake measured 3.1 magnitude and all were detected 25 earthquakes in the swarm from seven o'clock last night until midnight.

The announcement from the Office, said that the reason for the overestimation is that the very short time passed between them and the energy transferred between shaky. Further passage Meteorological experts revealed that the largest earthquake occurred at 23: 06 last night, 3.1 in size. The quake at. 23:05 was measured at 2.7 and PM. 23:07 quake measured 2.8. The notice says that may be difficult to estimate the size of the largest earthquakes in the swarm when such a short time in between.
