An eruption at Pavlof Volcano caused the Alaska Volcano Observatory to raise the level of alert on June 2. The observatory felt the need to raise the alert level after an ash cloud was released by the volcano that reached 22,000 feet.
The cloud stretched for almost 50 miles to the east of its peak, according to the Associated Press.
Volcanologists decided to raise the alert level at the volcano to "Warning" and the aviation color code to "Red." This indicated to locals that an eruption could take place soon.
The current eruption began on May 31, and lava has reached the surface, according to Scientist Robert McGinsey, who spoke with the Associated Press.
When asked how long the eruption could last, McGinsey said, "hours, days or weeks."
Over the weekend, a pilot reported a gas and ash plume of approximately 8,000 feet above sea level.
McGinsey says that aircraft flying below 25,000 feet should avoid the area for the time being.
The volcano is located on the Alaska Peninsula, approximately 36 miles northeast of the community of Cold Bay.
The 8,262-foot volcano is one of the state's most active, according to AP.
Pavlof last erupted in 2013, causing regional airlines to cancel flights to nearby locations.
