Hekla volcano (Iceland): news & activity updates

Hekla volcano (Iceland): small earthquakes

Strain and earthquakes under Hekla volcano (Iceland Met Office)
Strain and earthquakes under Hekla volcano (Iceland Met Office)
The volcano remains restless, but without any indication of an impending eruption (however, it is notorious for not giving much warning either).
3 tiny earthquakes, all below magnitude 2, occurred today and add to the ongoing series of occasional small quakes under the volcano.
Current GPS and strain (volume changes of the bedrock, a strong indicator immediately prior to an eruption, while magma is pushing upwards) measurements show no significant variations.

The volcano has drawn media attention and is being closely monitored as it is believed it is "ready" for a new eruption (although there are no current indications that one is imminent). ... [details]
GPS-measured deformation of HEKR station (Univ. Iceland), north of the volcano
lundi, juil. 01, 2013
The trend of rapid inflation that started in April has not continued, but was partly reverted and significant deformation has stopped for now. Nothing suggests for now that an eruption is imminent, but Hekla is known for providing close to no (seismic) warning before eruptions. [details]
GPS-measured deformation of HEKR station (Univ. Iceland), north of the volcano
mardi, avril 30, 2013
The famous Icelandic volcano is showing further signs that indicate an eruption could occur in a near future. Significant rapid inflation, concentrated in the northern part of the volcano, has been detected since early April and likely represents accumulation of rising magma underneath. ... [details]
mardi, mars 26, 2013
The Icelandic Meteorological Office has informed authorities about unusual seismicity at Hekla volcano, which could be a precursor to a new eruption, and increased the volcanic alert level to yellow. Monitoring of the volcano will be intensified, as Hekla is not only one of the most active, but also one of the potentially most hazardous volcanoes of the country. The last eruption was in March 2000. On average, the volcano has been erupting about every 10 years, and it would statistically seen be due for a new one. ... [details]
Earthquakes near Hekla since beginning of August
vendredi, sept. 14, 2012
Small earthquakes continue to occur around and beneath the volcano. At the moment, it does not seem a significant increase and we have no other data suggesting that the volcano should erupt soon (although it very well could). [details]
