Kvikugösin eru bláleit á meðan vatnsblandan er hvít.
Hitamælingar sýna að hiti í sprungum í botni gígsins fer upp í 550 til 600 °C. Það gefur ástæðu til að
ætla að fljótandi kviku sé að finna á um 3 til 5 metra dýpi undir gígyfirborði. Yfirborð á gasbreiðum
sem einkennast af kvikugasa virkni er um 250 til 300 °C heitt á meðan yfirborð sem gufuaugu rísa af
er um 100 til 130 °C.

The year 2015 was the coldest in Iceland since 2000, but this period has generally been abnormally warm so the average temperature was close to the 1961-1990 mean. In most parts of the country the precipitation was well above normal.

The average temperature in Reykjavík was 4.5°C, 0.2°C above the 1961-1990 mean. This is the 20th
