SUMMARY

Iceland has experienced 18,000 earthquakes in a week, indicating potential volcanic activity in the Fagradalsfjall area after 800 years of dormancy. The Icelandic Met Office reported a significant increase in seismicity, with the strongest quake reaching a magnitude of 5.4. The eruption at Geldingadalur, near Fagradalsfjall, began on March 19, 2021, prompting an elevation of the aviation color code to red. This eruption is characterized by low explosive activity and lava flows, with no significant ash fall reported.

PREREQUISITES
  • Understanding of seismic activity and earthquake magnitudes (e.g., M 2.0, M 5.0)
  • Familiarity with volcanic systems, particularly the Krýsuvík-Trölladyngja system
  • Knowledge of monitoring tools such as InSAR for ground deformation analysis
  • Awareness of aviation color codes and their implications for volcanic eruptions
NEXT STEPS
  • Research the geological characteristics of the Krýsuvík-Trölladyngja volcanic system
  • Learn about the methods used for monitoring volcanic activity, including InSAR and seismic data analysis
  • Study the implications of volcanic eruptions on local communities and aviation safety
  • Explore historical volcanic eruptions in Iceland and their geological impact
USEFUL FOR

Geologists, volcanologists, emergency management professionals, and anyone interested in the seismic activity and volcanic risks associated with the Reykjanes Peninsula in Iceland.

Interesting comment about the uplift of a wide area in the peninsula. The author suggests a great eruption than before.

... already a live webcam for the event o0)

Yes, they were real quick getting them up and running again a couple of days ago.
I still has them bookmarked/subscribed in Youtube from recent years

Smoke (or, maybe just steam) on the live cameras :wink:

Steam and sulfur dioxide, and probably CO2
  • A lava-producing fissure eruption is occurring closeto Litli-Hrútur mountain on the Reykjanes Peninsula.
  • The eruption is occurring in an uninhabited areaand it poses no immediate dangers to infrastructure.
  • The intensity of the eruption has decreasedconsiderably during the first 24 hours
  • Volcanic ash is not being produced by theeruption.
  • Close to the eruption, the main hazards are incandescent,flowing lava and volcanic gases.
  • Gas measurements at the eruption site during thefirst hours show levels similar to the 2022 eruption.
  • Flowing lava could also cause localised grassfires, which will further contribute to poor air quality close to the eruption site.

Seismicity intensified during 3-4 July. An earthquake swarm began at 1400 on 4 July and more than 1,600 earthquakes were detected beneath Fagradalsfjall, in the vicinity of the July 2022 dike intrusion, by mid-morning on 5 July. The earthquake locations became shallower within the first few hours of the swarm and by 5 July were at depths of 2-3 km. Seven of the earthquakes were above M 4, with the largest being M 4.6 recorded at 0821 on 5 July. At 1055 on 5 July IMO raised the Aviation Color Code to Orange (the third level on a four-color scale).
So looking at the video of the Litli-Hrútur eruption, one can see lava spewing from the fissure.Edit/update: Volcanic eruption has started near Litli-Hrútur
