The Civil Defense and Public Safety decided to reopen the eruption site in Meradalir to the public by 10:00 local time today.
The site was closed for tourists over the past two days (7th-8th August), in order to avoid the storm passing through the tourist attraction and keep the public safe.

The effusive activity continues with little changes over the past 24 hours.
Several fissure vents have been reduced to three vents since the eruption began, but continue at a higher intensity in each vent.
Pulsating lava fountains shoot a glowing plastic material up to 100 meters height that continues to feed the lava into a 1 km long stream toward the east of the crater (watch a video below).
A volcano-tectonic earthquake with magnitude M 4.1 occurred at 11:52 local time today on the Reykjanes Peninsula, west of Lake Kleifarvatn (5.6 km north-northeast of Krýsuvík, at 5.2 km depth).

The Icelandic Institute of Earth Sciences took lava samples on the first day of the new eruption in Meradölum.
Magnesium oxide (MgO) concentrations in rapidly cooled glass were measured approx. 7.5% with titanium dioxide (TiO2) and potassium oxide (K₂O) ratio of 0.25. The 2022 lava has a similar composition to the 2021 lava.
A current lava temperature of the new eruption is 1190-1200 °C.
Magma likely comes from the upper part of the earth's crust where has remained over the past months.
