Above Supervolcano Yellowstone awoke a geyser that slept 60 for years.

The Yellowstone Volcanic Observatory (USGS) recently published information that the September Spring geyser 15 made an ejection that reached 9 meters in height, writes Forbes.

The geyser not only threw water and stones into the air, but also covered part of the Upper Geyser basin with coins, jars and other trash that people have thrown at it over the past few decades.

Despite the fact that a comparable power surge occurred in the park in 2004, the last time such activity was in the Ear Spring geyser was observed in 1957. Repeated emissions have not yet been, but the water on the surface of the caldera retains heat.

This incident does not mean that the Yellowstone Volcano can explode at any time.

Yellowstone National Park is one of the unique geological sites on Earth. There are an incredible amount of geothermal pools and geysers, and a variety of minerals paint the water in incredible colors.

Geysers work the same everywhere, no matter what part of the world you are in. Cool water penetrates the crust and then into the magma source. It is very hot around, so the water heats up, reaches the boiling point, but due to the pressure of the surrounding rocks it does not boil. Then the heated water goes into shallow water, the pressure drops sharply, steam is formed - and the stream breaks out. This is a rough way to explain what a geyser is.

Due to the rather large magmatic source, Yellowstone Park is filled with geysers.

Steamboat Geyser is the highest active geyser in the world. It is located in the Norris Geyser basin and is capable of throwing out fountains that are 91 meter in height and 3-40 minutes long. But such eruptions are rare. Most often, geysers are the height of 2-12 meters and a duration of no more than 4 minutes.

This year, Steamboat Geyser has become more active than before. As of September 17, he has released 19 fountains, which is well above the annual average. Such activity of the geyser caused public concern, but the USGS assured that there was nothing to worry about. Scientists say that "these eruptions have no consequences for possible volcanic activity in Yellowstone."

Geysers and volcanic eruptions link one main source of heat, but this does not mean that the two phenomena are interconnected. Processes in the uppermost part of the crust control hydrothermal activity. Magmatic reservoirs are hidden for many kilometers deeper and controlled by completely different mechanisms.

It is not clear why Steamboat Geyser behaves this way. The National Park Service said that the geyser raged heavily in 1961, for the first time in half a century, before re-entering its normal rhythm. He also showed unusual activity from 1982 to 1983 year. After that, the geyser basically behaved quite calmly. Scientists say that unstable behavior is normal for all geysers, but the reasons for Steamboat Geyser activity remain unknown.

The same applies to the unusual behavior of Ear Spring. All this suggests only that scientists are far from all studied about the geothermal system of Yellowstone. For scientists, this atypical behavior of geysers is a positive factor, since they have more data for analysis and further research.
