Volcano and earthquake activity in Iceland
A new earthquake swarm is currently taking place 2 – 5 km NE of Hellisheiðarvirkun. But that is a geothermal power plant that operates in Hengill volcano. The largest earthquake so far is a ML1.5 in size when this is written at 03:27 UTC (04:27 CET). There is a good chance that this earthquake swarm …
A new earthquake swarm has started in Hengill volcano. This earthquake swarm is in the same location as a earthquake swarm that took place there few weeks ago (see here). So far this earthquake swarm has mostly been made out of small earthquakes. But all earthquakes are below ML2.0 in size so far. It is …
The Icelandic volcano known as Hengill did have a minor earthquake swarm of 20 something earthquakes today. This earthquake swarm might be related to geothermal power plant activity nearby (by pumping down or up water in the area). But at the moment I do not have it confirmed and this has also not been confirmed …
Earlier this week, an swarm of earthquakes started in south of Brennisteinsfjöll volcano, also known as Bláfjöll mountain. This earthquake swarm started on a west to east fault north of a lake called Hlíðarvatn. This earthquake swarm has only been minor earthquakes, with magnitudes in the range of Mw0,0 and up to Mw2,3 but at …

Today (9-November-2022) at 13:34 UTC an earthquake with magnitude of Mw3,2 took place in Hengill volcano. This earthquake was felt in Hveragerði town and in Reykjavík. Few smaller earthquakes followed the larger earthquake. It looks like this earthquake swarm is over or close to end. I don’t expect anything major to happen in this earthquake …

Today (10-January-2021) at 03:15 UTC an earthquake with magnitude of Mw4,1. This earthquake was felt far away as Reykjavík. A swarm of small earthquakes is currently ongoing in this area. This earthquake activity is in the Reykjanes volcano. Over 100 earthquakes have happened in this area for the last 48 hours. Most of them are …

During the night of 30-December-2018 at 02:54 UTC an magnitude 4,4 earthquake took place in Hengill volcano. This earthquake was felt over a wide area. Largest aftershock had a magnitude of 2,2 so far. The earthquake (green star) in Hengill volcano. Copyright of this image belongs to Icelandic Met Office. The earthquake as it appeared …

Since 04:49 UTC this morning (17 December, 2011) there has been an earthquake swarm in Hengill volcano. This earthquake swarm is due to hydro-thermal power production that is currently taking place in this area. But the Orkuveita Reykjavíkur (OR) is obligated to pump down cold water into the bedrock at depth that is greater then …

During the night there where two earthquake swarms in Iceland. One of this earthquake swarms was man made. The larger earthquake swarm was in Hengill volcano and was man made. It happens and the hydrothermal plant pumps down cold water into the bedrock and changes the pressure and strain in the bedrock and nearby sediments …
It appears that operations of Orkuveita Reykjavíkur are creating the earthquake swarms that have been seen in Hengill volcanoo. But as part of operations in Hengill geothermal plant they pump down cold water into the bed rock under considerable pressure. This is according to Sigþrúður Ármannsdóttir a geologist at Icelandic Met Office. But Vísir.is quoted …
