Zusammenfassung
Due to the recent eruptive and highly disruptive volcanic events in 2010 in Iceland, scientific and societal interest is overwhelming in gaining as much information as possible about the volcanic structures and processes to enhance the understanding of the partially glacier‐covered Eyjafjallajökull and Katla volcanic systems. Numerous petrological, geochemical and geophysical investigations of these systems have already been published. However, to date no electrical or electromagnetic data have been acquired on these two volcanoes to attempt to image the resistivity structure beneath and around them, although electromagnetic methods are far more sensitive to fluid distribution (in this case partial melt) than any other geophysical method. In July 2011, a pilot study took place to collect broadband magnetotelluric (MT) data around the Eyjafjallajökull. The MT data are supplemented with transient electromagnetic (TEM) measurements. This data set is the first one collected at these volcanic systems and will complement the existing geophysical data. Very fresh data and preliminary results from the experiment will be shown.
