the geothermal area beneath the ice cauldron. Steam explosions occur as the geothermal area adjusts to decreased water pressure resulting from the drainage of the cauldron. The explosions increase the amount of dissolved material in the floodwater, which is detectable downstream as a conductivity increase in the river

in the area and the monitoring of the Icelandic Met Office must be
secured before the area is opened for the public.
Countermeasures to reduce risk in the area will be taken and further opening of the area will then be decided.
Status:
Seismic activity in Bárðarbunga continues to diminish. Since last Tuesday about 80 earthquakes were detected in
the caldera. The strongest one was M2.5

for comparison, during
the first 24 hours following the 5.6 earthquake in Núpshlíðarháls, about 1700
earthquakes were detected in the area. "It is difficult to say whether the
activity is coming to an end or only temporarily reduced", says Einar
Hjörleifsson, specialist in natural hazards at the Icelandic Met Office.
"Given the number and magnitude of earthquakes in recent days, it is

All the activity is taking place in the area where, prior to the eruption, a magmatic intrusion was detected and mapped. In light of the recent developments, it cannot be excluded that more fractures will open along the same alignment.
Because of the lack of ash and the minor tephra emission in the atmosphere, the aviation color code
