On the 9th of July at 22:22:57 UTC a M5.2 earthquake occurred in the Reykjanes peninsula in southwest Iceland, at a depth of 5km (see map below; the red circle denotes the earthquake epicentre). The Icelandic Meteorological Office (IMO) reported that the earthquake was proceeded by a seismic sequence between Fagradalsfjall and Keilir caused by a magmatic intrusion just north-east of the location of the 2021 and 2022 Fagradalsfjall eruptions. According to IMO the intrusion than led to a volcanic fissure eruption that started Monday the 10th July at 16:40 local time.
An eruption in the same area in 2021 saw lava flows and fountaining for months, with hundreds of thousands of people heading to see the volcanic activity. Icelandic Civil Defence said it is dangerous to visit the current eruption area because of gas pollution and people should stay away. The eruption site is located about half way between the capital Reykjavik and the town Grindavik on the southern coast of the Reykjanes peninsula.
At time of writing the Icelandic airport authority Isavia reported that no ash has been detected in connection with the eruption and there is therefore no impact on air traffic.
The M5.2 earthquake was recorded by seismic stations operated by DIAS in the Irish National Seismic Network (INSN), see figure below.

The Reykjanes Peninsula in Iceland has suffered a series of earthquakes in the past few hours. This phenomena is known as an earthquake swarm. At the time of writing, there have been 725 quakes in the last 48 hours. The largest of which was a magnitude 5.7 that occurred at 10:05:57 on the 24th February 2021. This event was recorded by the Irish National Seismic Network and can be seen in the waveforms plotted below.
