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.
