Something Has Begun at Yellowstone Supervolcano
WYOMING — July 25, 2018
Strong seismic activity at Yellowstone National Park is giving scientists cause for worry: on the night of July 23rd to July 24th at least four seismographs began to show if not the beginning of an eruption, then at least an earthquake with a force of at least 5.0 points on the Richter scale:
At about 4:30 AM eastern Daylight Time (EDT) on Monday, July 23, something began happening at the Yellowstone supervolcano. Seismograms in several locations around the massive volcano began registering strong and non-stop activity underground.
NOT ALL of the seismograms are reporting this, but enough of them are, over the majority area around the supervolcano, to cause scientists to begin paying extremely close attention. This is what it looked like as of 8:49 AM EDT:
The trouble is not limited to a single seismogram, it is spread over a WIDE area beneath the volcano. Here is the seismo from miles away at a place called West Thumb:
Even farther away, another seismogram from Lake Butte:
Miles farther away, here is the seismo from a place called "The Promotory:"
However, if you look at the USGS website, you will see that there are few earthquakes in the area of the caldera. This can’t be or the USGS is hiding something. Therefore, it is impossible to understand from this diagram what is happening with the sensors.
But fortunately we have a lot of other sources of information.
Here is the screen of monthly dynamics of water temperature in Steamboat Geyser which USGS doesn't hide as it doesn't hide the temperature of the other geysers in the Park:
The temperature of the other geysers can be found here. Not every geyser has the same temperature dynamics as Porkchop Geyser: its temperature jumped from 70 to 85 degrees a month; but the temperature is rising EVERYWHERE. What does this mean?
Three processes are responsible for heat transfer from one physical body to another: conduction, convection and thermal radiation.
For today there is no direct contact of water with magma, the water is heated by the red-hot rock, which is heated by the magma in its turn. In case of direct contact of water with magma all water will be evaporated and the geyser will explode. But the geysers do not explode if the water accumulates temperature gradually. The gradual accumulation of temperature is possible only when it is transmitted by thermal radiation.
Therefore, if all the geysers of Yellowstone show a simultaneous increase in temperature, then the upper magmatic chamber will begin to emit more heat energy. The increased temperature also means an increase in the heat of the mantle plume, or the thinning of the layer of relatively cold rocks between the top of the plume and the magma chamber of the Yellowstone.
As far as modern theories of Geology can be believed, the temperature of the mantle is stable and at one or another depth is constantly within known limits. Therefore, if the mantle plume began to radiate more, this can only be due to the movement of its top closer to the surface.
The boiling point of the water is not high, so the geysers react first to this situation — they start to shoot more often and the water becomes hotter.
However, as the magma level increases, rocks start to melt, turning into magma and causing a series of small earthquakes.
Later, the softened rock will begin to fill the underground cavities, causing local collapses and, as a result, an earthquake of up to 5.0 points. It is possible that in this stage the process of the mantle plume movement will stabilize, although it is more likely that the process will have further development. No one knows what will happen in that case.
It would be great if southeast of the Caldera a new geyser pool starts to form, which will form some new fissures (rocks there are already cracking) and Yellowstone begins a leisurely eruption of the Hawaiian type. But this is a very optimistic scenario. The geologists say that supervolcanos tend to explode.
Yellowstone is one of only 14 "Super" volcanoes on this planet; and it is the ONLY one on land.
It is two THOUSAND TIMES bigger than Mount Saint Helens which erupted in Washington state in the 1980's.
NO ONE IS SAYING THERE IS ANY ERUPTION PENDING, but if an eruption did take place, it could literally wipe out every living thing within 500 miles in all directions during the first HOUR of any such eruption.
As volcanic ash is hurled high into the atmosphere, prevailing winds would carry it to the entire western two-thirds of the United States, killing crops and cattle - imperiling our food supply - and changing the weather across our entire PLANET for years.
There is no reason to PANIC. If authorities determine that an eruption is becoming likely, they will give all of us warning.
So don't go off half-cocked and start acting like this is the end of the world. If danger arises, we WILL get warning.
However, prudence dictates we pay attention to what is taking place so we have our own "heads-up".
