Measurements of lava flow: The latest data on lava flow and lava flow are based on yesterday's flight. Aerial photographs were taken from Garðaflug's aircraft with the Hasselblad camera of the Icelandic Institute of Natural History, and land models of the lava in and around Geldingadalur were made based on them. The results are the total flow from all craters over a six-day period, 12-18. April had on average been almost 8 m3 / s. This is a slight increase from the average flow in the eruption and confirmation that in parallel with the opening of more craters last week, the power of the eruption has increased somewhat, the area of the lava has reached 0.9 km2 and the total volume is now over 14 million. cubic meters. Work on processing geochemical and gas data is ongoing and the graphs will be updated as soon as it is completed. Lava flow compared to other eruptions (written 19 April) The eruption has now lasted for one month. The average lava flow for the first 30 days is 5.6 m3 / s. Compared to most other eruptions, the flow is relatively stable. The measurements on the lava now show that there has been some increase in the last 1-2 weeks. The average flow for the first 17 days was 4.5-5 m3 / s, but for the last 13 days it is close to 7 m3 / s. A comparison with other eruptions shows that despite the increase, the flow is now only about half of what occurred on average in the first 10 days at Fimmvörðuháls in the spring of 2010, which was a small eruption. A comparison with Holuhraun shows that the current flow is 6-7% of the average lava flow during the six months that the eruption lasted. The flow is similar to what was longest in Surtsey after the eruption began there in April 1964 until the end of the eruption in June 1967. It is not possible to say now how long the eruption will last, but the development of lava flows over time will give indications in the future.
