Kiruna, Sweden
30 Aug 2022 • (Don't laugh
)
So, here is today's article about a small earthquake in Kiruna, in the extreme north of Sweden, where they mine for iron/steel (which lead to that the city of Kiruna was/is being moved to a different place due to the risk of collapses there.
However, in the article BIG words are being used...for a 2.2 M earthquake, which I don't know if i should laugh, or finding it sad how reporters are using super sensitized language... If it would been the M 4.5 earthquake in 2020, i could understand... but 2.2
.
Well; welcome to 2022; small events, big words.

Stort skalv i Kirunagruvan: ”Det skakade i hela huset”
Ett rejält skalv skakade Kirunagruvan under tisdagseftermiddagen. Skalvet hade magnituden 2,2, enligt LKAB. ”Det skakade i hela huset”, skriver en kirunabo på Facebook.

Big quake in Kiruna mine: "The whole house shook"
Updated today • (30 Aug 2022) 18:32
A major quake shook the Kiruna mine on Tuesday afternoon. The quake had a magnitude of 2.2, according to LKAB.
"It shook the whole house," writes a Kiruna resident on Facebook. An area of the mine has been closed since the quake, according to LKAB. But no people have been injured. - There has been a pretty good subsidence, Per Juntti, communicator at LKAB. The quake measured 2.2 magnitude according to the first information from LKAB. That would make it the biggest quake in the mine so far this year.
"The porcelain vibrated". On social media, Kiruna residents write that they have felt the blast all the way to the new town centre, about four kilometres away. "The whole house shook and the glass cabinet with fine china vibrated badly," writes one Kiruna resident on Facebook.
Previously hit by major quakes
Quakes in Kiruna are not uncommon. On 18 May 2020, the mine was hit by Sweden's largest ever mine quake.
That time, the quake reached a magnitude of 4.8 on the Richter scale. LKAB has still not been able to resume full production in the part of the mine that was hit. It is unclear how the mine will be affected by Tuesday's quake.
Settlement earlier in the day: On the night of Tuesday, another seismic event occurred, with a magnitude of 1.6 on the local scale.
Could they be related?
- Hard to say, we are waiting for more information, says Per Juntti.
See the images from the 2020 quake area in the clip below:
(video in the linked site, in Swedish, from 2020 after 4.5 M earthquake)
In the clip you can see drone footage from the "Block 22" area in the Kiruna mine. Photo: SVT
I've got a few images from Kiruna's mine

However, in the article BIG words are being used...for a 2.2 M earthquake, which I don't know if i should laugh, or finding it sad how reporters are using super sensitized language... If it would been the M 4.5 earthquake in 2020, i could understand... but 2.2
If the translation is accurate, the article mentions:
The people of southeast Asia, Chile and Japan who are constantly being hit by M5+ would surely also be laughing at the sensitized language of the report.

When I saw this earthquake I started to compile data because there is a geologist in Mexico who assures that Mexico is the antipode of Carlsberg Ridge, then he foresees an earthquake of great magnitude, greater than 6 degrees in fact, between September and October of this year.
▪︎Carlsberg Ridge (between the horn of Africa and India) recorded three M4 earthquakes (4.7, 4.6 and 4.8) on August 28.

▪︎The geologist mentions another example. On August 28, 1973 at 09:50 UTC the Orizaba Veracruz earthquake occurred with a magnitude of 7.5.
▪︎The geologist claims that there was an M5.5 earthquake at Carlsberg Ridge that year. Unfortunately I could not find a record of that earthquake on the internet due to the moderate magnitude.

Date: 29 Aug 2022 | Time: 19:41:12 UTC | Location: 37.74 N ; 14.76 E | Depth: 18 km | Ml 3.5
After low seismicity on Etna in recent months, a new swarm quake occurred yesterday evening. It manifested itself under the western flank of Fire Mountain and consisted of 29 tremors with magnitudes between 2.2 and 3.5, which are reported at the EMSC. There were probably also a large number of weaker earth tremors that do not appear in the tables. The INGV is not yet ready to display the quakes. A communiqué was announced, but apparently not linked on the website. The epicentre of the strongest single earthquake with M 3.5 was located 11 km northwest of Adrano. Its hypocentre was at a depth of 18 km. The earthquakes are not all located under the volcano flank, some also hit an area close to the volcano base. It is very likely that they are related to magma uplift. The region is also a typical location along which there have often been swarm quakes as a result of magma rise. The earthquakes do not necessarily have to be of volcanotectonic origin. Tectonic earthquakes on fault zones can also be triggered by stress changes caused by rising magma.
It is interesting that the tremor has been decreasing since the end of last week. Until then it was on the borderline between yellow and red, now it has clearly shifted to yellow. So it doesn't look like an eruption is imminent in the short term, although of course the tremor can rise in minutes before paroxysms. However, I do not expect new paroxysms now.
Etna is in a consolidation phase and is refilling its magma reservoirs. In the past, this process often took several months, sometimes even years. Of course, eruptions can always occur, but these are then often of a Strombolian nature and are limited to the summit craters. There are currently no indications of an imminent eruption.
Limited public relations work by INGV and LGS
Unfortunately, the public relations work of INGV and LGS regarding Etna is weakening. The INGV published the last weekly bulletin on Etna on 2 August. Maybe the person in charge is just on holiday, or maybe it only comes irregularly. Publication was already suspended in April. The LGS website has been down for a long time and only shows data on Stromboli, but has stopped its daily bulletin updates. I can only speculate about the reasons: perhaps it was due to a lack of money/personnel, or because they no longer want to make their data available to the general public. In any case, it is a regrettable trend.
Update: In the meantime, 39 quakes with magnitudes between 1.5 and 3.5 have been reported by the INGV.

PS:
I need to ask Sal my husband, if his sister, brother and mom have felt these earthquakes, since they live in the city of Adrano.

An addition to what @Puma already reported revolving the swarm earthquakes located under the Etna Volcano. Vulkanet.net wrote an article about it as follow:
Ätna: Schwarmbeben am 29.08.22 - Vulkane Net Newsblog
Unter der Ätna-Westflanke gab es ein Schwarmbeben. Es ist das Stärkste seit vielen Monaten. Wahrscheinlich steigt Magma auf.

Addition to the Etna earthquake swarm.
I just asked my husband if anyone in the family felt something. The reply was that nobody in the whatsapp family group mentioned anything. So i guess, there was no drama what so ever ;)
I find it a bit surprising that 39 earthquake shakes flew under the radar…
