The Icelandic Met Office (IMO) reported that the CO2 emissions reached hazardous levels and low levels of O2 were measured at the cave (popular for hikers) in the Eldvörp area on the Reykjanes Peninsula on 20 February.
On 20 February an earthquake swarm started 10 km N of Gjögurtá. Over 200 earthquakes were detected by the seismic network with magnitude below M 3.0.
Earthquake swarms are not unusual in the area.

Reykjanes volcano (Reykjanes peninsula (SW Iceland)) activity update: Alert level raised to Yellow- earthquake swarm, inflation

InSAR data showing inflation. Credit: IMO.

IMO reports: An inflation has been detected since January 21st and is centred just west of Mt. Thorbjorn on Reykjanes peninsula. The inflation is unusually rapid, around 3-4 mm per day and has accumulated to 2 cm to date. It has been detected both on continuous GPS stations and in InSAR images. The inflation is most likely a sign of magma accumulation at a depth of just a few km. If magma accumulation is causing the inflation, the accumulation is very small, with the first volume estimate is around 1 million cubic meters. Read all
