Experts from the Institute of Natural Sciences and Land Survey of Iceland conducted a survey flight over the eruptions on 8 April, gathering data to estimate the size of the lava bed and lava flow. The results indicate a steady decrease in eruption intensity.
Lava flow dicscharge rate
The average lava flow discharge rate from craters between April 3 and 8 was estimated at 3.6 ± 0.7 m3/s. This is a decline from the average flow rate of 6.6 ± 0.3 m3/s recorded from March 27 to April 3, as reported by the Efla Engineering Institute based on drone data from April 3.
Lava flow area
The lava bed covers an area of 6.14 km2 with a volume of 31.3 million m3. Recently, the lava has predominantly flowed south from the crater, with a temporary northward surge on April 7 when the crater rim ruptured.
The thickest lava accumulations are observed near the crater and slightly to the south, where activity remains highest within the lava bed. There are no clear indications of lava advancing towards the dikes north of Grindavík, Suðurstrandarveg, or Melhólsnámu, according to the latest observations.
