Eruption confirmed in Fagradalsfjall mountain

This article is going to go get updated soon as possible or a new article is going to be written. This information is going to get outdated quickly. This is Krýsuvík-Trölladyngja volcano.

This volcano eruption seems to have started without any earthquake activity or major harmonic tremor as of writing of this article. More information later this evening.

Update at 22:46 UTC

Here is a web camera link from Rúv. It might work. But all the web cameras are getting heavy traffic now.

Update 22:56 UTC

This is the possible location of the eruption based on satellite images of the area. This is in eastern side of Fagradalsfjall mountain. This is from Icelandic Met Office.

Inflation slows in Krýsuvík-Trölladyngja volcano system

This is a short article that because the situation can change without warning and article is written on 19-March-2021 at 21:07 UTC. There have been updates to names used and now Krýsuvík-Trölladyngja name is used by Global Volcanism Program and Icelandic Met Office. Suggesting that the magma that is about to erupt has its origin in Krýsuvík volcano system eat of current centre of activity. This sometimes happens in Iceland when magma travels long distances deep underground.

Today at 15:01 an earthquake took place with magnitude of Mw3,1. This earthquake has in my view clear signs of magma movement close to the surface as the depth of this earthquake was just 0,1 km (100 meter).

A magnitude Mw3,1 earthquake that took place today at 15:01 UTC.

This earthquake strongly suggests that magma created it at shallow depth. It has not yet resulted in an eruption but it is a question if this the final sign before an eruption happens. The current quiet time might last up to 2 months but it is impossible to know for sure.

Update on the activity between Keilir and Fagradalsfjall mountains

This is a short article written on 17-March-2021 at 17:49 UTC. The situation can change without warning.

It has been less activity in in Fagradalsfjall volcano (Krýsuvík volcano). Current day to day change is not a lot at the writing of this article but it is also possible that bad weather that is now passing over Iceland is masking some of the smaller earthquakes in the dyke between Keilir mountain and Fagradalsfjall mountain. Inflation continues at what seems to be about the same rate as yesterday (16-March-2021).

Earthquake activity shows but less then in last few days. Most of the red dots are located between mountain Keilir and Fagradalsfjall mountain after change in earthquake after the weekend

Number of strong earthquakes has dropped after the strong earthquake activity during last weekend (12 to 14 March). What also changed is that the dyke can’t move more south then it already has. It seems that it hit a impasse in the crust that it was unable to break or go around (harder crust is the most common why this happens). The current status is a waiting for the eruption to start and when that happens is impossible to know.

Since there is not a lot of change going on at the writing of this article I am going to slow down the number of updates I am posting. Next update is going to be when something happens or at the latest Monday 22-March 2021.
