Scientists studying Yellowstone’s Mount St. Helens believe they have found evidence of volcanic activity.
The results of a new study published in the journal Nature show that the volcano’s summit erupted in April of 2015, sending debris that spewed lava and ash into the air and igniting the nearby Mount St Helens National Park.
The findings could help scientists understand how Yellowstone’s volcano behaves.
“We can get a sense of how the volcano has been doing in the past, which might be an indicator of what’s going to happen in the future,” said the study’s lead author, Andrew Miller, a geologist at the University of Montana.
Miller and his colleagues used seismic data from Mount St Helen to calculate how much ash fell and how quickly it rose into the sky.
The data revealed that the ash fell at an average rate of roughly 4,000 cubic meters a second.
That’s roughly 1,400 cubic meters of ash per second.
But there were more rapid rises of ash, the researchers found.
The rate of ash rising to the summit in April 2015 was more than three times the average rate over the past five years.
This was a very rapid increase, and that’s what’s exciting about this study,” Miller said.
The researchers also measured the volcano.
They found that in April, the volcano erupted at an altitude of nearly 4,400 meters, making it the highest point on Earth.
The researchers were surprised by the explosive eruption.”
It was the most intense and the most destructive event on the volcano,” Miller explained.
Miller’s team’s research is part of the larger study of volcanic processes.
It is also supported by NASA.
The Mount Sthelens volcano is located near Yellowstone National Park and the summit of the volcano is about 5,400 feet above sea level.
Miller said he is surprised by what he found.”
It was really interesting.””
We haven’t seen that since 1980.
It was really interesting.”
He said this study is important because it helps scientists understand what’s happening to the volcano and what might happen to the surrounding region in the next decades.
The study was published in Nature Geoscience.
