The data showed that magma is rising in a United States volcano that’s been long dormant about 6 miles from a depth of about 12 miles.
It has caused significant surface deformation, according to researchers.
“That’s the fastest rate of volcanic deformation that we currently have in Alaska,” said the research paper’s lead author, Ronni Grapenthin, a University of Alaska Fairbanks associate professor of geodesy.
“And while it is not uncommon for volcanoes to deform, the activity at Edgecumbe is unusual because reactivation of dormant volcanic systems is rarely observed,” he added.
Mount Edgecumbe is a dormant volcano located on Kruzof Island in the Alexander Archipelago of Alaska.
The last known eruption of Mount Edgecumbe was approximately 800 years ago.
Showing activity means that there are signs of volcanic activity such as increased seismic activity, gas emissions, or changes in the shape of the volcano.
While there is no way to predict with certainty, the current activity of Mount Edgecumbe does not necessarily indicate an imminent eruption. It is important to continue monitoring the volcano and follow any evacuation plans put in place by local authorities.
Scientists use a variety of methods to monitor Mount Edgecumbe, including seismic monitoring, gas measurements, and satellite imagery. These tools help scientists to track any changes in activity and provide warnings if necessary.
