and gusts measuring 45.8 m/s were recorded at the height of the storm, setting new wind records since automatic measurements began in town in 2002.
At Stórhöfði, the famous synoptic weather station located on Heimaey island's southern tip, the automatic weather station recorded wind-speed* of 44.6 m/s and gusts of 52.7 m/s, the highest since it was set up in 2004. However, that time-span

Jamison and Cook (1978) analyzed the state of stress in the crust based on a set of some 50 3-D stress
measurements from all over the world. They found a linear relationship between the maximum shear
stress and the sum of the maximum and minimum

The DOAS will be tested for any damage it may have suffered during months of being surrounded by hot lava and gases. It will be fixed and set back up near the eruption, where it will make continuous SO2 emission rate measurements that are streamed back to IMO.

Preliminary maps were produced considering a short meteorological data set (one month); and were only done for 50% and 90% likelihood of occurrence.
A more proper data set of runs was done using 10 years of meteorological data from the ECMWF and probabilistic hazard maps accounting

A Scientific Advisory Board was formed to discuss the evolving situation. Procedures for sending monitoring teams into the field were practiced and the set-up of new equipment for taking ash samples was tested. FutureVolc partners were able to practice evaluating monitoring data from seismometers, radar and GPS stations, the acquisition of satellite data

at the mapping of the surface of the largest glaciers using laser technology from airplane. The project is endorsed by the Icelandic Polar Year Commission. It set out in September 2008, comprising Hofsjökull, Mýrdalsjökull, Eyjafjallajökull, Eiríksjökull and Snæfellsjökull.
The outlines of Icelandic glaciers have been registered, using maps, aerial photographs and satellite images. The data has been

Currently the area around Fagradalsfjall is characterized by low level of seismicity and no detectable deformation.
The aviation color code for Fagradalsfjall volcano is set to green as the current level of activity is considered to be within the known background.
The area continues to be closely

) since the start of observations in 1873. The summer was rather dull in the Northeast.
The dry spell ended everywhere by 20 August and an equally unusual wet spell set in. The
remaining part of the year was the wettest ever registered in the South and West and the year
as a whole was the second wettest on record in this area. The precipitation totals in the North
and East were close
