Magnitude mb5,2 earthquake in Central Mediterranean sea, south of Malta

Today (30. January 2023) at 19:55 UTC (20:55 CET) an earthquake with magnitude of mb5,2 took place south of Malta in Central Mediterranean sea. According to reports to EMSC, this earthquake was felt in Malta. Damage is unlikely because of distance from populated areas. This is not the first earthquake in this area and this earthquake activity is what I consider interesting.

Since there’s a slight chance it might be volcano or magma related, but I am not sure on that because I don’t have any good knowledge of this area. There might be a volcano in this area, but for same reasons as before. I am not sure because of my lack of knowledge of this area. Maps, good as they are, don’t show any noticeable features on the ocean floor in this area.

Information about this earthquake can be found here on EMSC website.

Magnitude Mw5,9 earthquake in Iran, close to border with Turkey

Today (28. January 2023) an earthquake with magnitude of Mw5,9 took place in Iran, close to the border with Turkey. According to EMSC reports this earthquake was felt over a wide area. I don’t know if any damage happened, but that is likely if housing is of poor construction. Landslides might also have happened in areas closest to the earthquake.

Magnitude Mw5,9 earthquake in Eastern Mediterranean Sea

While Iceland is quiet I am going to start writing about earthquake activity around the world. I can’t write about eruptions that are happening globally, because I lack the knowledge to do so. This articles won’t be detailed. Just short information about earthquakes above magnitude Mw5,0 in Europe and earthquakes above Mw6,0 in the rest of the world. I’ll continue to write this articles until the quiet period stops in Iceland.

Earthquake with magnitude of Mw3,8 in Katla volcano

Today (18. December 2022) at 11:08 UTC an earthquake with magnitude of Mw3,8 took place in Katla volcano. This earthquake was felt, I don’t know if it was felt in Vík í Mýrdal. This is the largest earthquake in Katla volcano in a while.

There has been some earthquake activity with minor earthquakes following this strong earthquake. But it has been minimal at the writing of this article.

Magnitude Mw3,1 earthquake in Katla volcano

Today (16. December 2022) at 21:44 UTC an earthquake with magnitude of Mw3,1 took place in Katla volcano. This seems to be a single earthquake at the writing of this article.

This earthquake activity seems to be normal and there is nothing to suggests that more is going to happen in Katla volcano at this time.

Magnitude Mw3,8 earthquake in Bárðarbunga volcano

Today (29-November-2022) at 01:09 UTC an earthquake with magnitude of Mw3,8 took place in Bárðarbunga volcano. This is a normal inflation earthquake in Bárðarbunga volcano and more earthquakes like this are going to happen in next few years.

This is just regular earthquake activity in Bárðarbunga volcano. After the eruption in Bárðarbunga volcano in 2014 and until 2015 it is going to be a while until next eruption happens. Until then, earthquakes like this are going to happen.

Earthquake swarm in Kolbeinsey island (north of Grímsey island)

Today (22-November-2022) an earthquake swarm took place in Kolbeinsey island. This is far north of Grímsey island. Largest earthquake had a magnitude of Mw3,1 and total of four of those earthquakes happened. More than dozen smaller earthquakes have happened. Because how far this activity is from Icelandic Met Office SIL network only the largest earthquakes are being measured.

Green stars far north on the map, north of Iceland. This is the location of Kolbeinsey island. There are dots all over Iceland showing smaller earthquakes.

What is going on is unclear. This might just be normal tectonic activity for this area. There is only poor monitoring of this area since its out in the ocean and remote.

Increased earthquake activity off the coast of Reykjanestá

Today (20-May-2022) around 18:00 UTC the earthquake activity off the coast of Reykjanestá, that is part of Reykjanes volcano, increased again after few days of little earthquake activity. The earthquake swarm is ongoing and always changing so this article is going to be short because of that.

Largest earthquake so far had a magnitude of Mw3,8 and the second largest earthquake had a magnitude of Mw3,5. The Mw3,8 earthquake was felt in Grindavík and on nearby towns on Reykjanes peninsula. A Mw3,0 earthquake took place just north of Grindavík and was felt in the town.
