IMO’s specialists performed gas measurements at the eruption site. There are indications that gas emission from the eruption is slightly lower than yesterday, however gas concentration close to the lava flow were measured above danger threshold.

Skjáskot af óróagrafinu á vaktinni sýnir aðdraganda gossins. Sáralítill órói sést hægra megin á myndinni og aðeins á mælum sem eru næst upptökunum, sjá neðstu línurnar á grafinu. Um kl. 20.45 hefst gosið með stöðugri virkni, tímaskalinn er neðst á myndinni. #Reykjanes #Eldgos

Óholl loftgæði í grennd við eldstöðina í kvöld. SV-læg átt, gert ráð fyrir vindstyrk undir 3m/s. SO2 gæti farið yfir 9000 µg/m3. Heilsuverndarmörk eru 350 µg/m3. Ráðlagt að yfirgefa svæðið fyrir 17:00, fara ekki í dali/dældir og halda sér innan stikuðu gönguleiðarinnar. #eldgos

New satellite images of Öræfajökull volcano shows that a new ice-cauldron has formed within the caldera. It seems that geothermal water has been slowly released from underneath the cauldron to the glacial river of the Kvíárjökull outlet-glacier.

Talið er að ef til goss kæmi yrði það á sprungu einhvers staðar á svæðinu þar sem kvikugangurinn er að myndast. Jarðskjálftavirkni utan svæðisins við kvikuganginn er merki um spennulosun en ekki að þar undir sé kvika á hreyfingu. #jar ðskjálftar #Reykjanes
