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.

: No detections over the eruption site since 19 April 2010
Noises: Report from ~20 km SE of the volcano of booming sounds (02:30 GMT)
Meltwater: Continuing discharge of water from Gígjökull due to ice-melt at the
eruption site. Discharge at the old Markarfljót bridge, 18 km from
Gígjökull, is estimated at 110–130 m3 s–1, of which 30–40 m3 s–1 is
baseflow.
Conditions at eruption site: No visual

A scientific
article by Icelandic glaciologists is an important contribution to global studies
and assessments of climate change. The average mass loss of the Icelandic
glaciers per unit area in recent decades is among the highest on Earth.

peak discharge of 250 m3 s–1 two hours later at the bridge. Both yesterday
and today, mean discharge from Gígjökull was 130–150 m3 s–1, which is
higher than in previous days. The electrical conductivity of Krossá and
Steinholtsá remains high (see report from 28 April for details).
