The Semisopochnoi Volcano in Alaska has been placed on high alert due to tremors and ash.


The Semisopochnoi Volcano in Alaska has been placed on high alert due to tremors and ash.

After tremors and ash outbursts were reported, the warning level for a volcano in Alaska’s Aleutian Islands was raised. Here’s the most up-to-date information.

The US Geological Survey (USGS) said that the Semisopochnoi Volcano began rumbling on Thursday and erupted on Monday, with ash emissions and “continuous shaking.” The alert level has now been raised as experts continue to closely examine the activity.

The USGS has changed the aviation color code from yellow to orange, and the volcano alert level has been raised from “advisory” to “watch.”

These degrees of warning imply that a “volcano is demonstrating heightened or growing disturbance with greater potential for eruption, timeframe unknown.”

The Alaska Volcano Observatory (AVO) has reported that ash emissions are continuing, with a plume stretching 350 kilometers (215 miles) to the southeast at an altitude of about 6,000 meters (20,000 feet) above sea level.

“Satellite observations from yesterday afternoon revealed a vigorous steam plume and sulfur dioxide gas emissions,” according to the AVO.

“These findings imply an increase in disturbance, and the Aviation Color Code has been raised to ORANGE, and the Volcano Alert Level has been raised to WATCH,” the AVO continued.

“An increase in ash emissions is likely, but not certain.”

This kind of activity isn’t uncommon in Alaska, which has over 40 active volcanoes.

Many of these occur along the Alaska Peninsula and Aleutian Islands, which are made up of 14 large volcanic islands and 55 smaller islands that make up the so-called Ring of Fire.

Semisopochnoi Island is made up of many volcanoes and is one of the largest volcanic islands in the western Aleutians.

Mount Cerberus is the most active of the island’s three younger volcanoes.

The AVO has classed Semisopochnoi volcano as a “restless” volcano.

Since September 2018, small eruptions creating tiny ash deposits in the volcano’s neighborhood have been the norm during unrest at Semisopochnoi, with the most recent activity observed in June 2020.

The volcanic explosion on Semisopochnoi Island is uninhabited, and no one is in immediate danger.

Volcanic ash rising from the Aleutians, on the other hand, could cause problems for trans-Pacific planes flying between Asia and North America.

Volcanic ash, which is made up of microscopic rock pieces, can do substantial damage to planes flying through it, as well as boat and automobile engines that breathe ash-filled air.

Volcanic ash is abrasive and harsh, and it can swiftly cause damage. “Brinkwire News in Condensed Form.”
