In full swing again.
After taking an apparent break for eight and a half days, the main crater by Fagradalsfjall, Southwest Iceland, once again began spewing fire into the air on Saturday, mbl.is reports.

Scientists visited the site that day and made some interesting discoveries, according to the Facebook page the Volcanology and Natural Disaster Team of the University of Iceland, where they posted the accompanying videos. The team points out that there is every indication the eruption did not stop during this pause in surface activity. Clearly, the opening of the main vent clogged up, preventing magma from flowing into it.

La Palma volcano (Canary Islands): strong seismic swarm suggests magma intruding at depth

swarm
A strong earthquake swarm started under the area of La Cumbre Vieja volcano in the southern part of the Island yesterday. So far, more than 350 tremors have been detected, including 14 quakes of magnitudes above 3.0 and 226 quakes between 2.0 and 2.9.

The strongest was a magnitude 3.4 event at 00.46 am local time this morning, which was felt by nearby residents.

Most earthquakes are at shallow depths around 8-12 km, suggesting that new magma is currently intruding into a reservoir under the volcano. Whether or not this might be leading up to new volcanic activity is impossible to say at this stage, as there seem not to be other signs of significant volcanic unrest at this stage. Similar earthquake swarms have occurred in the past as well, most recently in late Dec last year; however back then, the quakes were deeper (at around 30 km depth), which could indicate that magma has now risen higher in the volcano's underground storage systems.

La Cumbre Vieja volcano last erupted in 1971, and it is considered one of the most active volcanoes of the Canary Islands. The situation clearly merits close monitoring.

Uplift detected at Askja volcano in Iceland, began end of July

Askja
© Wikipedia
Askja is located in Iceland. Pictured here in 1984.
GPS observations and ground deformation maps derived from Sentinel-1 satellite data reveal that Askja volcano began inflating at the beginning of August 2021. The uplift signal is centered on the western edge of Öskjuvatn, close to Ólafsgígar, and corresponds to ~5 cm/month of vertical motion. Geodetic modelling (performed using both GPS and satellite data) indicates that the source of this inflation is located at a depth of approximately 3 km and corresponds to a volume change of approximately 0.001 km³/month.

The cause of such inflation is uncertain, but most likely it is due to the inflow of new magma. Askja volcano is seismically active and earthquakes are regularly measured in the area.

Comment: Note that just a few days ago in Iceland it was reported that rivers down stream from volcanoes and a glacier recorded an increase in harmful levels of sulphuric acid, thought to be related to changes in geothermal and volcanic activity. This also comes on the heels of an overall uptick in activity in the region; back in March 2021 the following article reported: 34,000 quakes in two weeks near Fagradalsfjall volcano, Iceland - 900% increase in activity compared with whole of 2020

Flooding & sulphuric smells at rivers in Iceland linked with change in geothermal & volcanic activity

The river Skaftá in Southern Iceland has been seeing changes in recent days indicating a flood has begun.

Electrical conductivity in the river has increased steadily over the past two days, an indication that geothermal factors are involved. The water level has also risen in the past few hours, according to MBL. According to the Icelandic Meteorological Office, sulphuric smells have also been reported in the vicinity of Skaftá and Hverfisfljót.

Residents and passersby in the area are encouraged to remain diligent and apprise themselves of potential changing conditions in the area. Flooding over the riverbank and across nearby roads is possible in the next few days.

Comment: Regarding activity at Vatnajökull, Wikipedia notes:
In more modern times, the volcanoes continue to erupt beneath the glaciers, resulting in many documented floods. One jökulhlaup in 1934 caused the release of 15 km3 (3.6 cu mi) of water over the course of several days.[5] The volcanic lake Grímsvötn was the source of a large jökulhlaup in 1996.[6] There was also a considerable but short-lived eruption of the volcano under these lakes at the beginning of November 2004.[7] On 21 May 2011 a volcanic eruption started in Grímsvötn in Vatnajökull National Park at around 7 p.m.[7] The plume reached up to 17 kilometres (11 mi).[7]

Italy's Mount Etna erupted on August 29 spewing ash and lava after weeks of calm.

This footage by Giuseppe Tonzuso shows the volcano spraying debris and bright red lava down the side of its southeast crater as smoke and ash billow skyward.

Ebeko volcano sends forth column of smoke after erupting on Kuril Islands, Russia

An ash eruption of the Ebeko volcano was seen on the Paramushir island of the Kuril Islands, reported the Kamchatka Volcanic Eruption Response Team, on Wednesday.

"According to visual data of volcanologists from Severo-Kurilsk, the height of the ash release was up to 3.7 kilometres (2.29 miles) above sea level," the experts said.

According to the response team, Ebeko's ash emissions could cause problems for local airlines. The volcano's Aviation Colour Code status warning was placed at orange.


Comment: A day earlier a strong magnitude 6.0 earthquake was registered off the Kuril Islands.

This Aug. 13, 2021 photograph provided by the U.S. Geological Survey shows the crater of the Kilauea volcano south of Honolulu. Geologists on Tuesday, Aug. 24 said they had detected a swarm of earthquakes at the volcano, though it is not erupting.

Geologists on Tuesday said they had detected a swarm of earthquakes at Hawaii's Kilauea volcano, though it is not erupting.

The quakes began overnight and continued into the morning, The Hawaiian Volcano Observatory said.

More than 140 earthquakes were recorded as of 4:30 a.m. The largest was magnitude 3.3. Most were less than magnitude 1.

The renewed explosive activity continues.

As we reported in the latest report, the volcano produced the submarine explosion on 13 August.

The Japan Coast Guard made a flight observation that confirmed the height of the eruption column.

The spectacular white steam and gas plume rose to estimated 16 km (53,000 ft)! altitude and spread into an umbrella cloud.
