statistics are calculated for locally flat terrain. For Part 3, the locations of the 14 test sites (see
Figure 1) were chosen based on either particularly high wind energy potential at a given elevation,
or due to their proximity to existing power plants, making it easier to integrate locally generated

year's expedition. The depth and width of the cauldrons has not been measured for quite some time, such measurements can only be carried out with airborne surveillance. Therefore no statement can be made on changes in geothermal activity from last year.
A new seismographic station was installed at approximately 1600 meters elevation northwest of the Bárðarbunga caldera on June 5th. The station

indicates that about 60 million cubic metres of material are in motion. It is possible that the entire mass may be released as a single rockslide, it is also possible that the material may be released as several smaller rockslides. The age of these fractures is not well known. They are not visible on aerial imagery from the year 2003 but they are evident in an elevation model from 2011, indicating

The vertical displacement (m) was monitored by near real time presentation of data from a GPS station, mounted in the middle of the caldera.
