a debris cone in the run-out zone. The
source of the material is either within in the channel or in the talus slope above the channel.
Most of the landslides that occur in Strandartindur are debris flows of this type.
B Debris slides that are not confined to gullies and occur near a concave break of slope. The
main type of material is debris mixed with fine-grained material. Most of the landslides

specific window lengths, the appropriate triggering signal-to-noise ratio falls somewhere
between 1.1 and 1.4.
Logarithmic scaling on the vertical axis enhances weak tremor signals, making them easier to
identify at an early time. When logarithmic scaling was applied to the STA and LTA averages,
however, it became clear that this would require very fine tuning, as many

on young, porous lava fields adjacent to the river, both in the highlands and
the lowlands. Such sedimentation progressively fills the lava, allowing

or no volcanic activity has been observed since 23rd May but scientists have not yet declared that the eruption is over.
What kind of an eruption is it?
The eruption is an explosive eruption beneath a glacier. The ash is fluorine rich, of intermediate silica content and the particles are very fine.
Is the ash dangerous?
Yes, the fluorine is dangerous to livestock. The fine ash can also effect human

Colour: Dark-gray at 6 km (seen on webcam).
Tephra fallout: Ash has fallen in the Gnúpverjahreppur area, on the road to
Stultartangi Power Station and in the Biskupstungur area (very fine-
particled and gray).
Lightning: Constant lightning (up to 10 flashes per hour) has been detected.
Noises: In Hafnarfjörður.
Meltwater: Low water discharge at Gígjökull.

couple of days.
Overall assessment: There is still a considerable amount of steam coming from the
crater. The tremor is still higher than before the onset of the eruption,
and small tremor pulses have been detected on the lowest frequency.
Very fine ash has been blown up, but it does not go very high up in the
air, but covers the volcano so it can not be seen on webcameras..

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
