A heatwave in Iceland
New absolute maximum temperature record in Reykjavík
31.7.2008
During the the last week of July, Iceland experienced a rare heatwave. It culminated on 30 July, when new records were set. The maximum temperature in Reykjavík

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 is short compared to 90 years of manned observation at Stórhöfði.

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.

in a project sponsored by the U.S. Coast and Geodetic Survey. The aim of this project was to set up an international seismic network, and in 1964 a station was installed in Akureyri as part of the World Wide Standardized Seismograph Network.
From 1925 to 1964, IMO was the only institute in Iceland monitoring seismicity. In 1964, the Science Institute of the University of Iceland installed a seismograph

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

and procedures introduced by FutureVolc.
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
