Svartsengi volcano update: weak seismic activity detected since 4 November

In the early hours of 4 November, a brief swarm of earthquakes was recorded along the Sundhnúkur crater row.
Since then, the seismic activity in the area has remained low, with only five minor earthquakes detected after the swarm subsided. Recent strong winds may have impacted the earthquake detection system, making it harder to capture the smallest tremors in the region.
Meanwhile, the ground uplift and magma accumulation are ongoing in Svartsengi. The magma volume beneath Svartsengi is now approximately 80% of what had built up before the eruption that began on August 22. If the accumulation rate holds steady, it could soon reach the levels observed just before the last dike intrusion and eruption. However, the Icelandic Meteorological Office anticipates that an even larger volume of magma will be necessary to trigger the next intrusion beneath Svartsengi.
