of the volcano, in addition to
vertical subsidence. These observations are consistent with deflation of a magma reservoir
beneath Eyjafjallajökull.
Magma flow: No measurements possible today; however, the intensity of the eruption suggests
that the discharge level is similar to the preceding four days (i.e. 20–40 tonnes s–1).
Other remarks: No measurable geophysical changes within the Katla volcano
