The last critical planetary alignment according to SSGEOS will occur in a few hours on June 5 involving Earth, Mercury and Uranus.

Uranus appears to be a key indicator with the occurrence of great earthquakes. In the last 600 years the greatest earthquakes occurred when Uranus was conjunct or opposite the constellations Aries (25%), Leo (55%) and Sagittarius (20%).

Let's wait and see.

● Earthquake Forecast

Major seismic activity for the first days of June has not occurred so far. The only M6+ earthquake occurred on May 31 in New Zealand that preceded the conjunction Venus Mercury Neptune
2023-05-30.png
M 6.2 - Auckland Islands, New Zealand region
2023-05-31 02:21:21 (UTC)
Apparently no fault section reached the inflection point that was anticipated following the critical planetary geometry.

This is interesting because if we look at the averages every 2.7 days an M6+ earthquake occurs after planetary conjunctions and 8 days ago it has not occurred.

Conjunctions are coming up next week
● Mercury Sun Mars on June 09th.
On the 13th a convergence of two planetary conjunctions
● Sun Mercury Neptune early
● Followed by Venus Mercury Jupiter later that day.
2023-06-08-overview.png

We could see strong to significant seismic activity after this convergence. Most likely around June 14 or 15.

As for the Atmospheric Fluctuations we had several fluctuations that marked the Eastern Pacific regions repeatedly since day 4 but so far no major seismic activity in the Americas.

Switzerland | Austria | Italy | Germany • Large landslide
12 June 2023

German Vulkane.net wrote an article about a large landslide on/at a mountain. Since the writer is an avid climate change guy, it is all about climate change being the primary reason behind the landslide. The videos posted at Twitter do give a glimpse of that this must have been a huge landslide, as if "half of the mountain side was coming down"

PS: i had a little bit difficulties to nail down the exact location, in which country the event was located, because their territory seem to be all located in the area. Instead, i listed them all ;-)

Violent landslide on the southern Fluchthorn triggers earthquake and 'catastrophic atmosphere'

A violent landslide occurred yesterday on the Southern Fluchthorn near Galtür in Tyrol, causing the mountain to lose part of its summit. The event manifested itself around 3:30 p.m. and was captured on video. In the landslide, part of the upper northwest flank of the Southern Fluchthorn sheared off; even the summit cross was swept away and tumbled to the valley. The landslide caused a 2 km long debris avalanche and a torrent that flowed towards the valley.

Although it was a huge event, there was no damage to infrastructure, nor do any people seem to have been affected. Therefore, it is a natural phenomenon rather than a natural disaster. Landslides have existed since the beginning of mountain building and are normal geological processes.

Nevertheless, it is assumed that the landslide is related to anthropogenic climate change, because the peaks of the affected mountain massif are almost 4000 m high and are thus located in the permafrost zone of the Alps, which is above 3000 m. The ground here is normally completely frozen. Normally, the ground here is frozen all year round. This is also true for the water in rock crevasses. Due to global warming, the altitude of the permafrost region is shifting and the thawing of soils and rock crevasses can destabilize mountain slopes and lead to landslides.




Shocks from landslide registered as earthquake

Bild_2023-06-12_151549108.jpg

Of course, other events can also trigger landslides. These include earthquakes. This once prompted me to check with the EMSC whether there was an earthquake in the Alps. Indeed there was, because at the same time as the landslide an earthquake of magnitude 2.2 was registered at the Fluchthorn. It has a negative depth indication and manifested itself at a height of 2 km, that is, in the mountain massif. I suspect that it was not the earthquake that triggered the landslide, but that the tremors originating from the landslide were registered as earthquakes.

On the shakemap you can also see that there was a weak earthquake south of the Fluchthorn before, but whether this shaking triggered the landslide is unlikely.
 
Campi Flegrei - Pozzuoli, Napoli, Italy
11 June 2023
A mild earthquake occurred in Pozzuoli, the town that lies near the center of the Campi Flegrei submerged caldera, and marks with this a stronger earthquake compared to e previous peaks (recently there was a M 3.0 if i recall correctly). Supposedly, the M 3.6 earthquake was the strongest earthquake in the area in the past 40 years. The gradual increase of unsettledness in the past year in that area, does give me some worry...

German Vulkane.net wrote an article about it:



Earthquake ML 3.6 shakes Italian caldera volcano Campi Flegrei

Date 11.06.23 | Time: 06:44:25 UTC | 40,831; 14,111 | Depth: 11 km | ML 3.6


cf.jpg

This morning a magnitude 3.6 earthquake struck the Italian caldera volcano Campi Flegrei. The hypocenter was located at 2600 m depth. The epicenter was located on the coast east of Monte Nuovo and west of Solfatara crater. The earth tremor occurred at 06:44:25 UTC (08:44:25 local time) and could be clearly felt by local residents. The EMSC has received corresponding reports. According to these reports, the earthquake was felt for 4 to 5 seconds. Together with another earthquake M 3.6, which had occurred in March last year, the earthquake is one of the strongest of the current uplift phase.

Earthquake activity has been quite high in the Campi Flegrei area for several weeks. There is practically a continuous swarm earthquake in progress, with several weak tremors occurring daily. The INGV monthly report for May states that 661 tremors were recorded. A value close to the peak in April, when 685 tremors occurred. The values this year lead the top of the histograms of the current uplift phase and show that seismicity has increased significantly. Nevertheless, twice as many earthquakes were recorded at peak times during the 1980s uplift phase.

Ground uplift remained high in May at 15 mm per month. This value was measured at the RITE monitoring station. Looking more closely at the readings, we see a slight subsidence for the last few weeks in May. It looks as if the ground elevation occurs in phases during which it increases strongly and then stagnates or decreases slightly for a few weeks. In the weekly report for the first week of June, one can see that currently there is again an uplift phase. The uplift is still given by INGV as 15 mm/month.

The gas temperatures of the main fumarole of Pisciarelli continue to average 96 degrees.

Volcanologists conclude that the general trend described for months is continuing and do not see any worrying changes in the behavior of the caldera volcano. For residents of the region, of course, the development is worrying, even more so when there are noticeable earthquakes, as was the case today. Then people become aware that they are living on a powder keg. According to a new study, the risk of eruption is greater than many specialists had assumed.

Potential for rupture before eruption at Campi Flegrei caldera, Southern Italy​

Abstract

Volcanoes reawakening after long repose must rupture the crust before magma can erupt. Rupture is preceded by repeatable variations in the rate of seismicity with ground movement, which trace the amount of applied stress that is released by local earthquakes. A rupturing sequence has been developing across four episodes of ground uplift at Italy’s Campi Flegrei caldera: in 1950-1952, 1969-1972, 1982-1984 and since 2004. We predicted in 2016 that the approach to rupture would continue after an additional uplift of 30-40 cm at the location of largest movement. We have updated our analysis with new data on changes in the numbers of local earthquakes with amounts of ground movement. Here we show that subsequent events have confirmed our prediction and that the unrest has been changing the structure of Campi Flegrei’s crust. The results provide new constraints for evaluating the volcano’s potential to erupt or to subside without eruption.

Tectonic Summary
The eastern margin of the Australia plate is one of the most sesimically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.

Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Nine of these, and the four largest, occurred along or near the Macquarie Ridge, including the 1989 M8.2 event on the ridge itself, and the 2004 M8.1 event 200 km to the west of the plate boundary, reflecting intraplate deformation. The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke's Bay earthquake, which killed 256 people. The last M7.5+ earthquake along the Alpine Fault was 170 years ago; studies of the faults' strain accumulation suggest that similar events are likely to occur again.
