of low frequency tremor indicative of volcanic activity.
Earthquakes: At 17:44 GMT yesterday, a magnitude 1.6 earthquake was recorded
beneath Grímsvötn. Several micro-earthquakes were detected at grf
during the onset of heightened tremor at 02:30 GMT; these events were
local to grf and probably sourced from the ice. Between 09:03 and
10:45 GMT four tectonic earthquakes were

(approx. 3 km high) and white when the flight arrived at Grímsvötn but at 20:55 GMT explosive activity increased again and the plume rose to about 7.5 km height. The increased activity was observed for about 20 minutes, then the activity dropped down at 21:15 GMT and increased again at 21:45 GMT. This pulsating activity is also clearly seen on tremor plots (click to enlarge) from near seismic

:54 and 02:45, more than thirty
earthquakes were located at depth greater than 20 km and magnitude
less than Ml 2. A few more earthquakes were detected until morning.
GPS deformation: Horizontal displacements towards the center of Eyjafjallajökull
volcano and subsidence. Some irregular movements are seen in the
height of the stations closest to the volcano.

and or degassing from the craters. Visibility to the
bottom limited due to steam.
The crater rim is coated with fine ash that extends me 20 m from the
edge. Strong smell of sulfur around the craters. At 20:45 the steam
plume was measured to be at the altitude of 2.8 km.
Seismic tremor: Volcanic tremor is still more than before the eruption and has been
rather steady since 22nd May, but small pulses

Since the end of the Holuhraun eruption in February 2015, 45 earthquakes of magnitude larger than M3 have been detected around the Bárðarbunga caldera, 42 of them since 1st September 2015 and 31
