The largest active volcano in Washington was threatened with a series of earthquakes, putting experts at a state of high alert.
Mount Adams is Stratovolcano, which is 12,000 feet in southern Washington, about 55 miles southwest of Yakima.
This volcano is a “great threat” because of its ability to operate the landslides, ice collapses and mud flow that can travel up to 50 miles per hour to the bottom of the slope, putting thousands of people at risk.
American geological survey experts (USGs) says that although this volcano has not erupted for about 1000 years, it will definitely lead to the outbreak again.
But it is impossible to say exactly when it will explode, which is why scientists have created monitoring stations around the Adams Mountain to track its seismic activity.
Between September and October last year, these screens discovered nine earthquakes ranging from 0.9 to 2.0 around the volcano.
The Adams Mountain usually tests one earthquake every two to three years, according to USGs.
While increasing seismic activity He can Be a sign that the volcano is about to explode, the experts emphasized that this series of tremors appears to be a “natural background activity” and does not mean that the eruption of Mount Adams is imminent.

But the biggest threat to people living near this volcano is not an explosive eruption.
It is actually ice collapses, landslides, and virginity, or muddy flows of rocks, ash and ice that “rise in the direction of the river course such as rapidly flowing concrete” and can occur during periods of explosions or unstable, according to USGs.
USGs wrote: “The ice -covered summit hides large quantities of weak water rocks, and the future terrestrial collapses of this weak rock can be born to far -fetched indexes.”
In the light of recent earthquakes, scientists have installed three additional monitoring stations around the volcano to monitor this.
“We went up and worked with the forest service to put three additional temporary stations,” said Holly Weiss Rakin, the awareness coordinator of the Cacekids Observatory (CVO). Kgw8.
“They are working with solar energy, so they will be able to tell us when there is an earthquake,” she added.
These additional stations will help scientists at CVO and the northwestern seismic network in the Pacific Ocean (PNSN) to investigate the size, location and depth of earthquakes, according to USGs.
This will improve our ability to locate smaller earthquakes with more certainty and help understand the cause of these earthquakes. USGs officials wrote about our results if any additional procedures are needed statement.

Since October, seismic activity has faded around Mount Adams. But the researchers will continue to watch the volcano closely to see if it is presented again.
In addition to helping scientists evaluate the possibility of the explosion of Mount Adams, the new screens will also help them answer long -term questions about this volcano, Weiss Rakin said.
She said: “We do not have a lot of basic information about Mount Adams. We have watched the mountain over the past 42 years, but the volcano has been present for hundreds of thousands of years.”
For example, these screens should help researchers determine the activity of Mount Adams.
In some cases, earthquakes near volcanoes can lead to an eruption.
But this only happens if the earthquake is large (larger than size 6) and the volcano is already preparing for outbreak.
When these conditions are met, the earthquake can cause magma -dissolved gases similar to the shaken soda bottle, which increases pressure inside the volcano and may lead to a revolution.
But these nine earthquakes were very small so that they did not raise the eruption.
The Adams Mountain is approximately 520,000 years ago. It is located about 70 miles northeast of Vancouver, Washington and Portland, Oregon.
Even through Mount Adams, a volcano is a “great threat”, which has not erupted for thousands of years.
Scientists have estimated that its latest eruption took place between 3800 and 7600 years.
Throughout its history, the Adams Mountain has mainly produced outstanding revolutions, which differ from explosive explosions in that they do not send lava, gas and ash in the sky, but they constitute slow lava flows that crawl on both sides of the volcano.
