Iceland Geology YouTube channel

I’ve made the chose to start Iceland Geology channel. This is going to allow me to upload geology information in video format. How that is going to evolve is unclear, but I am going to work on this slowly over the next few years.

Iceland Geology YouTube channel can be found here. I have uploaded few videos, but since the channel is just recently in use I am still going trough verification process with YouTube. That limits my number of uploads until those are lifted. Since I am for now just uploading older videos that I’ve recorded in last few years.

Information for webicorders (online again from May or June) and e-mail postlist signup website are now under Iceland Geology menu option.

Earthquakes far off the coast on Reykjanes ridge

Yesterday (30. January 2023) had two earthquakes with magnitude Mw3,2 far off the coast on the Reykjanes ridge. Only one smaller earthquake was detected. Distance from the SIL network makes detection of smaller earthquakes is impossible or really difficult.

Besides this earthquake activity, it remains quiet in Iceland. Bad weather has also been blocking detection of earthquake activity for the last two weeks.

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.

Flood risk in Iceland on 20 and 21. January 2023 because of sudden warming after long time period of freezing weather

I normally write about earthquakes and volcanoes in Iceland. This is a little change from that. Starting tomorrow (20 and 21. January 2023) there’s a flood risk in all of Iceland as there’s going to be a sudden warm and there’s a lot of snow and rivers have frozen over in last few weeks in Iceland. There’s a lot of flood expected all over Iceland, along with risk of avalanches from mountains and other snow and rain and water related floods. Travelling might get risky or impossible because of flooding and melting snow.
