The eruption is now almost a week old and shows little signs of stopping anytime soon. Activity is now concentrated at two adjacent vents of a growing cone in the central part of the original eruptive fissure. They are filled with spectacularly boiling (degassing) lava that flows away to form thin flows that overlap on a growing lava field, that slowly but surely is filling the Geldingadalur valley.

The eruption continues with little changes, but it has provided scientists already with very interesting results that might provide unique insights into a type of eruption that hasn't been observed on Iceland in a long time.

The eruption continues with little changes and stead lava output. In the past hours, the hornito (small cone-shaped vent) at the side of the main vent has been becoming more active, seen left in the image of the live camera.

Vigorous lava spattering is seen from the main vent, which has been building a steep-sided cone above the eruptive fissure. Over its two and half days of existence, this cone (also called a hornito currently) has been growing, sometimes partially collapsing, and thus changing its shape a lot, and it might evolve eventually into a new small mountain.

The new eruption, now called the "Geldingadalsgos" eruption by the Icelandic media, continues steadily. It has been producing slowly advancing lava flows inside the Geldingadal valley. The Icelandic Met Office and local news outlets published many new photos from the ongoing eruption this morning.

The new eruption is located near Geldingadalir, around the center of the recent dike intrusion of magma that has formed under the peninsula over the recent weeks. It started very quietly with almost no seismic activity when finally, a fissure opened, reaching around 500-700 m length.

Recent earthquakes in the Reykjanes peninsula
The earthquake swarm in the Reykjanes peninsula, concentrated in the area around Mt. Fagradalsfjall SW of Keilir, continues with no signs of weakening. By early afternoon, the Iceland Met Office (IMO) had already recorded over 1700 earthquakes since midnight alone, including many of magnitude 3 or higher and a widely felt
magnitude 5 event at 07:53 GMT this morning.

In recent reports, the Icelandic Meteorological Office (IMO) stated that magmatic movements are the likely cause of the ongoing earthquake swarm in the Reykjanes peninsula. As magma migrates upwards, overlying rock layers are displaced, which causes tremors and ground deformation on the surface.

The Icelandic Met Office (IMO) announced earlier today, that the total number of earthquakes in the region has exceeded 34,000 since the onset of the seismic swarm about 2 weeks ago.

As the number of earthquakes recorded in the Reykjanes Peninsula, Iceland, surpassed the 20,000 mark, the main area of unrest was identified as the area between Fagradalsfjall and Keillir. According to the Icelandic Meteorological Office (IMO), magma intrusions under the surface are the prime suspect to cause this ongoing seismic activity.

A strong seismic crisis has been occurring on the Reykjanes peninsula near Fagradalsfjall mountain since mid Feb 2021, involving several magnitude 5+ and thousands of smaller ones. Volcanic tremor has appeared recently as well, indicating that magma movements underneath are likely accompanying and/or causing the seismic swarm. A new eruption in the area is a likely scenario.

The situation remains tense. A large
magnitude 5.0 quake occurred last night at 02:02 about 3 km WSW of Fagradalsfjall. IMO reported that additionally, from midnight over 30 earthquakes over M3 and 5 larger than M4 have also been recorded.

For more than a week now, Iceland's Reykjanes Peninsula has been continuously rocked by an intense earthquake swarm: A total of more than 20,000 tremors have been recorded since the activity started on the Reykjanes Peninsula on 24 February 24 when a magnitude 5.7 quake occurred, followed almost immediately by a magnitude 5.0 event.
