An eruption started in Holuhraun north of Dyngjujökull at around 00:02. Seismic tremor was observed on all seismic stations. It is a small fissure eruption and at 02:40 AM the activity appears to have decreased.
Summary of the eruption from the Icelandic Met Office:
At 00:02 UTC signs of a lava eruption were detected on web camera images from Mila. The web-camera is located at Vaðalda, north-east of the eruption site.
– Around midnight, weak signs of increased tremor were apparent on IMO’s seismic stations near to the eruption site. At 00:20 UTC scientists in the field from the Icelandic Met Office, Institute of Earth Sciences and Cambridge University confirmed the location of the eruption.
– The eruption occurred on an old volcanic fissure on the Holuhraun lava field, about 5 km north of the Dyngjujökull ice margin. The active fissure was about 600 m in length.
A small amount of lava drained from the fissure and by around 04:00 UTC, lava flow is thought to have stopped.
– According to seismic data and web-camera imagery, the eruption peaked between 00:40 and 01:00 UTC.
– At the beginning of the eruption, seismic activity decreased, although seismicity has since returned to levels observed in recent days.
– Aerial observations by the Icelandic Coastguard show that only steam is rising from the site of the lava eruption.
– There are no indications that the intensity of the activity declining.
