(ORDO NEWS) — Scientists around the world are realizing that if a supervolcano erupts in Yellowstone National Park, the consequences of the event will be felt by the whole world. That is why the situation is constantly and carefully monitored by geologists from the United States.
The last time the volcano emitted lava 640 thousand years ago. Today, major changes are taking place on the giant’s territory, which was described by University of Utah professor Robert Smith, who has been watching Yellowstone since the 1960s.
So, for scientists it was a real insight that the volcano’s caldera rises at great speed. After another rise, a swarm of earthquakes followed.
The surface in the period from 2004 to 2010 rose by 25 centimeters per year, and now this figure reaches 40 centimeters annually. The course of all processes in the volcano has accelerated, stated Robert Smith.
Scientists additionally noted that earthquakes are some kind of safety valves that protect humanity from a real threat. If there are many tremors in the region, it means that liquid is ejected from the magma, and this is quite normal. If this process stops, then magma will begin to rise to the surface.
Regular monitoring of the level of soil deformation allows specialists to monitor the state of the volcanic system as a whole and assess possible risks. So far, there are no signs of an impending eruption.
