Today (12-November-2021) at 05:05 UTC an earthquake with magnitude of Mw3,2 took place 3,3 km South West of Keilir mountain. This earthquake was felt up to Borgarnes town.
Earthquake activity continues close to Keilir mountain. But it remains at depth of 5 to 6 km and doesn’t show any sign that it is about to move to the surface. More than 10000 earthquakes have been recorded and 18 earthquakes have been recorded with magnitude above Mw3,0. This is according to Icelandic Met Office.
The eruption in Fagradalsfjall mountain (more information at Krýsuvík-Trölladyngja website at Global Volcanism Program) has not been active since 19-September-2021 and there are no signs that the eruption is about to restart soon. Global Volcanism Program no longer updates its information for this volcano as an active eruption. Icelandic scientists in eruptions have not declared the eruption over. It should be expected that the eruption in Fagradalsfjall mountain is over for now, but it can start again at the same location or at new location in few weeks time or maybe even few years from now.
On Saturday 25-September-2021 an earthquake swarm started close to Keilir mountain, at the writing of this article this earthquake swarm is ongoing.
The eruption in Fagradalsfjall mountain has been having its longest quiet period since 19-March-2021 and at the writing of this article that is ongoing situation.
This earthquake activity suggest that the eruption time period in this part of the Reykjanes peninsula is not over, even if nothing is happening at the moment.
Krýsuvík-Trölladyngja is a volcano system is currently erupting in this area.

This is unconfirmed so there might be number of other reasons why this is being observed. This also might be wrong reporting but based on web cameras that might not be the case. There has been some visual view of this on web cameras. Here are two pictures that I was able to screen grab from two of those cameras.
It is unclear what is going on and this might all be wrong. But I am also seeing this new light source on the web camera from mbl.is on YouTube as it peaks a little from behind the large crater in Fagradalsfjall mountain. That crater is not active at the moment.
I don’t know when confirmation is going to appear. If this is an eruption. If this is not an eruption, then there is going to be a confirmation of that too. I’ll post update here is I learn anything more in the next few hours.
Update 03:07 UTC 7-September-2021
The light on the second picture (on the right) is a human made light. I think it is the lighthouse. What is appearing on the thermal camera has not been identified.
Update 13:36 UTC 7-September-2021
This is wrong reporting that happened here. Nothing happened and what was seen on the thermal camera is most likely the heat from the crater. This type of wrong information happens every once in a while. Currently the main crater remains inactive and sulphur colours have started to appear on him from the sulphur outgassing that is now happening.
