Не сразу человек понял, что на этой территории расположен и один из мощнейших супер-вулканов планеты Земля. Помогли снимки из Космоса.
Йеллоустон постоянно трясёт, но легко, для человека практически не заметно. Крупные землетрясения по человеческим меркам происходят достаточно редко – раз в 600 000 лет. Последнее, заметьте, произошло уже целых 630 000 лет назад... есть повод начать волноваться. Ну, а раз есть повод, то почему бы им и не воспользоваться?! Тем более, что в последнее время землетрясения, как будто бы, и усилились, и ускорились – стали происходить чаще, но мелкие. :) Однако самое неприятное – совсем недавно Йеллоустон тряхануло вполне заметно… :(
НО! Об этом прочитайте уже на английском. Давайте, давайте! Текст адаптирован. Зажмурились… и вперёд J
There Have Been 296 Earthquakes Near The Yellowstone Supervolcano Within The Last 7 Days
Is it possible that the Yellowstone supervolcano is getting ready for a major eruption?
eruption - извержение[READ IT!]
Scientists are telling us that everything is going to be okay, but there are others that are not so sure.
The biggest earthquake was measured to be a magnitude 4.4 earthquake. It was the biggest quake in the region since a magnitude 4.8 earthquake struck in March 2014.
The quake and aftershocks took place just over 8 miles northeast from West Yellowstone. The main quake was centered about 5.8 miles underground
Dozens of people reported that they felt it. A witness reported that she felt the building she was `in move.
By itself that one quake would not be very troubling. But this earthquake has been accompanied by 295 smaller ones.
There is normally a rise in seismic activity before a volcano erupts.
to erupt [ɪ'rʌpt] – извергаться
Scientists believe that there’s a 10% chance that a “supervolcanic Category 7 eruption” could take place this century.
What would it be like?
It has been estimated that 90 percent of all people living within 600 miles of Yellowstone would be killed.
Hot volcanic ash, rock and dust would rain down on Salt Lake City and Denver for weeks.
Hundreds of cubic miles of ash пепел, rock and lava would rise into the atmosphere, and there would follow several days of complete darkness in the northern hemisphere.
The volcanic ash would contaminate most of our water supplies, and growing food in the middle of the country would become next to impossible.
In other words, it would be the end of our country as we know it today.
The rest of the planet, and this would especially be true for the northern hemisphere, would experience what is known as a “nuclear winter”. An extreme period of “global cooling” would take place, and temperatures around the world would fall by up to 20 degrees.
In the end, billions could die.
So yes, this is a threat that we should take very seriously.
The crust of our planet is becoming increasingly unstable,
but most of this shaking is taking place far away from the continental United States, and so most Americans do not worry about it. But a major seismic ['saɪzmɪk] event could change all of our lives in in a second.
That is why it is so alarming
that there have been 296 earthquakes near the Yellowstone supervolcano within the last 7 days.
