M6.5 earthquake in Idaho. Is Yellowstone or Rainier next?

On the night of March 31 to April 1 (2020-03-31 23:52:31 (UTC)) in the USA, in Idaho,a M6.5 earthquake occurred. The epicenter of the seismic event lies at a depth of 10 km:

This seismic event has become the second strongest in the history of the state. The first place is occupied by an earthquake in the same area, on October 28, 1983, the magnitude of which was 6.9 points.

At the moment, information about the victims and damages is only being collected, but all this is not the main thing. The main thing here is different:

The Roller City of Kelowna, British Columbia, Canada is is more than 700 km from the epicenter in the north direction, more precisely – a little to the north-west, or more precisely – along the line of the so-called Challis Arc:

The Challis Arc is a volcanic field with a length of about 1,500 kilometers, the origin of which is not very clear. It is assumed that the field appeared as a result of subduction of the ancient Kula / Farallon plate under North America:

The ancient plate partly sank, displacing magma, which, in turn, climbed out of volcanoes. The partly remains of Kula / Farallon were absorbed into the base of North America. All together, this led to the appearance of corrugated belts along the west coast. One of these belts is called the Challis Arc:

Thus, the epicenter was somewhere in a zone of very deep subduction and the earthquake mechanism there looks something like this:

That is why the earthquake was felt in Canada, that is, along the Challis Arc, but it did not spread a thousand kilometers to the West, East and South.

The mechanism of the earthquake is known, the earthquake is not very unusual, and the topic could be closed. However, the problem is that Utah and Idaho appear in a series of prophecies that promise a series of cataclysms to the United States. if we talk about earthquakes, we explained the mechanism above: the cause of the earthquake in Idaho and the previous earthquake in Utah are the ancient pieces of the lithosphere floating under the continent.

For some reason, fragments of these plates intensified: maybe they started to sink again, maybe they decided to float – we don’t know this. But we know that according to one theory, Yellowstone was the result of flooding / melting of fragments of the Farallon plate. The same goes for the Cascade Mountains. Therefore, if the Farallon plate suddenly became active – now we need to wait for major news from the Rainier volcano or even from the world-famous caldera!

A strange phenomenon in the Arctic, the cause of which is unknown

A strange phenomenon in the Arctic, the cause of which is unknown 128

In 2018, a plane flying over the Greenland glaciers noticed strange holes in the ice. NASA scientists cannot yet find the reason for their appearance.

The Arctic is a mysterious place, and as the Earth’s climate changes, it changes faster than scientists can record. So, according to NASA, strange holes began to appear in the ice, and so far no one can understand what causes them. 

The photo was taken by John Sonntag, a scientist working for NASA’s IceBridge operation, an ambitious mission to capture as much detail as possible of the North and South Poles in hopes of figuring out what is happening right now in these remote parts of the planet.

Unfortunately, this photo raises more questions than answers, at least for now. But even though scientists from IceBridge do not have an exact answer to what these holes are, they make assumptions. / These holes may be caused by ice melting due to the water warming under the ice, or they may be air pockets caused by whales or seals. However, for the latter variant the holes are somehow too big. 

NASA even asked its readers on the Internet for advice on what it might be. There were many assumptions, but it is not yet possible to say exactly why these holes formed.

Rich people from all over the world are buying submarines

The wealthy around the world will spend millions of dollars on private submarines, following Russian billionaire Roman Abramovich, The Times reports.

According to the publication, in the period from 2019 to 2020, it was about the sale of 15 to 25 submarines, however, this number is expected to double in 2021. According to representatives of the three leading submarine manufacturing companies, next year the market will be estimated at 75 million pounds.

Among the first buyers of deep-sea vessels were the owner of Chelsea Football Club Roman Abramovich, the late Microsoft founder Paul Allen and the Emir of Abu Dhabi, Sheikh Khalifa Al Nahyan.

Roy Heijdra of the Dutch company U-Boat Worx noted that wealthy people increasingly want their yachts to be specially equipped for exploration, not just luxury holidays. According to him, ten vessels were sold in 2020 worth up to £ 2.2 million each. Among them was the Nemo model, which is estimated at 875 thousand pounds, has a height of 2.8 meters and can dive to a depth of more than 90 meters with two people on board.

In turn, the executive director of the Florida company Triton, Bruce Jones, said that compared with the previous year sales of submarines this year rose by almost a third, despite the pandemic coronavirus. At the moment, he has about five orders that need to be completed by the beginning of 2021.

A prehistoric forest that grew on earth a million years ago was found on the slope of Kilimanjaro

Just 300 kilometers south of the equator is the highest point in Africa, the potentially active stratovolcano Kilimanjaro, which covers an area of ​​more than 390 hectares. But as a free-standing mountain, the climatic zones of which become less and less like a terrestrial landscape as it rises, Kilimanjaro is especially notable as an incubator for isolated, mutated or rare species that are almost never found anywhere else. 

Recently, on one of the slopes, scientists discovered plants of a prehistoric forest. They grew on Earth a million years ago.

Senecio kilimanjari is a giant plant. It has practically not changed over the past million years, dinosaurs once roamed in the same forests. The territory of the giant groundwort begins at an altitude of 3000 meters. There is less rainfall and therefore the prehistoric forest is not so dense. This only further emphasizes the monumentality of the giant plants standing separately from each other, capable of growing up to 5-7 meters.

To survive in such a harsh environment – high in the mountains, temperatures regularly drop below zero during the night – the plants have developed water accumulation in the core of the stem, the movement of nyctinous leaves (which means that the leaves close when the temperature drops too much), natural ‘antifreeze “And self-isolation due to wilted and dead foliage (one of the reasons terrestrial plants look so strange).

The prehistoric forest rises to about 4,300 meters. Above the slopes of Kilimanjaro, only a barren alpine desert begins, ending in a colossal glacier at the very top of the stratovolcano.
