A “seismic crisis” has been occurring in the area near Fagradalsfjall since late Feb 2021. This activity has been interpreted as intrusion of magma at shallow depths, which could lead to a new eruption.
Fadradalsfjall is a Pleistocene table mountain in the Reykjanes Peninsula, NE of Grindavik, Iceland.
Very little is known about the eruptive history of the volcano; but according to both VolcanoDiscovery.com and Volcano.si.edu, no eruptions have occurred during the past 10,000 years — in other words, it’s anyone’s guess what this volcano is capable of when it does blow.
Kristín Jónsdóttir, of the Icelandic Met Office (IMO), has said the likeliest location for a eruption on the Reykjanes peninsula would be just south of Fagradalsfjall. Referring specifically to the recent seismic crisis and uptick in tremor pulses, Jónsdóttir added: “I think this is a sign the magma dyke is growing very fast.”
The IMO has stated that magmatic movements are the likely cause of the ongoing earthquake swarm in the Reykjanes peninsula–a swarm that has now totaled 34,000 quakes in two weeks (for reference, the average annual earthquakes across the peninsula is just 1,000-3,000). As magma migrates upwards, overlying rock layers are displaced, which causes tremors and ground deformation on the surface, explains VolcanoDiscovery.com.
Geophysical surveys were conducted along the area of unrest located between Fagradalsfjall and Keilir (see map below). The results generated a detailed look at how the expanding magma chamber under the Reykjanes peninsula behaves.
Jónsdóttir told mbl.is that the most active area is at the south end of the magma dyke, where the dyke not only seems to be growing toward the southwest, but also moving closer to the surface, to a depth of only about 1 km.
Of today’s reawakening volcanoes, those located in Iceland are perhaps the most concerning.
It is this highly-volcanic region that will likely be home to the next “big one” (a repeat of the 536 AD eruption that took out the Roman Republic…?) — the one that will return Earth to another volcanic winter.
Volcanic eruptions are one of the key forcings driving Earth into its next bout of global cooling.
Volcanic ash (particulates) fired above 10km –and so into the stratosphere– shade sunlight and reduce terrestrial temperatures. The smaller particulates from an eruption can linger in the upper atmosphere for years, or even decades+ at a time.
Today’s worldwide volcanic uptick is thought to be tied to low solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
The COLD TIMES are returning, the mid-latitudes are REFREEZING in line with the great conjunction, historically low solar activity, cloud-nucleating Cosmic Rays, and a meridional jet stream flow (among other forcings).
Both NOAA and NASA appear to agree, if you read between the lines, with NOAA saying we’re entering a ‘full-blown’ Grand Solar Minimum in the late-2020s, and NASA seeing this upcoming solar cycle (25) as “the weakest of the past 200 years”, with the agency correlating previous solar shutdowns to prolonged periods of global cooling here.
Furthermore, we can’t ignore the slew of new scientific papers stating the immense impact The Beaufort Gyre could have on the Gulf Stream, and therefore the climate overall.
Prepare accordingly— learn the facts, relocate if need be, and grow your own.
