The University of Iceland's Institute of Earth Sciences reported a summary of eruption parameters documented since March 19, since the eruption at Fagradalsfjall one month ago. The parameters showed lava flow discharge rate, lava area, lava volume, rock geochemistry and volcanic gases. The graph below depicts an overview of the results.

Lava flow discharge rate
The monthly average lava flow discharge rate at the eruption site is 5.3 cubic meters per second, which indicates a stable flow level in comparison to the most other eruptions.
The average discharge rate during the first 17 days after the eruption was approximately 4.5-5 cubic meters per second, but over the past 13 days the lava flow rate increased to 7 cubic meters per second. From April 12-18 it increased to a record 8 cubic meters per second.

Lava flow area
The lava flow area covered 0.89 square km.

Lava flow volume
Scientists estimate that approximately 14 million cubic meters of the lava have so far erupted from all vents.

Rock geochemistry
The graph shows the weight percent (wt.%) of magnesium oxide (MgO) (9%) and titanium oxide (TiO2) (1%) in the erupted magma.

Volcanic gases
Monthly average sulfur dioxide (SO2) emissions reached 2000 tons per day and carbon dioxide (CO2) emissions reached 5000 tons per day.
