by Alaska’s Mount Spurr, an active volcano near the most populated region of the state, comes even closer to an eruption, according to volcanologists.
Scientists from Alaska Vulcano Observatory measured the “significantly increased” emissions of Vulkangas, which come from Mount Spurr in Aleuten in Aleuten in Südalaska, about 75 miles west of Anchorage, according to a explanation that was published on Wednesday.
In addition, increased earthquake activity, ground formations and newly activated fumaroles – or gas ventilation – were recorded at the volcano crater peak, which indicates that the probability of eruption has increased, explained researchers from the observatory.

Small earthquakes have occurred over the ground on Mount Spurr since April, Matthew Haney, a scientist for the Alaska Vulcano Observatory in Anchorage, told ABC News last month.
A cross -flight on March 7th measured around 450 tons per day sulfur dioxide from the summit of Mount Spurr – an increase of less than 50 tons in December in December.
In the last month, more than 100 earthquakes per week have also taken place at the location. The soil deformation and breakdown of snow and ice in the Summit Crater Lake, which has also formulated during the unrest, also continues the scientists.
An increase in gas emissions confirms that new magma has entered the earth’s crust under the volcano, which points out that an outbreak is probably in the coming weeks or months.
While an outbreak is “not safe”, according to the observatory, it is the most likely result of the current unrest. If the magma places the surface and does not reach, the riots can decrease instead instead in the next few weeks and months, similar to the events from 2004 to 2006, researchers said.
The eruptions that occurred in 1953 and 1992 were explosive – a few hours lasted and produced ash clouds, which, according to the observatory, were worn against the wind for hundreds of miles. The outbreak in August 1992 meant that anchorage airport was closed for 20 hours due to the wind and ash event that accompanied the outbreak.

According to the observatory, there have been only a few geological evidence in the past 5,000 years that they propose other previous outbreaks in the past 5,000 years.
The volcanic warning level for Mount Spurr was at “yellow” or “advice” from Thursday, which points out that the volcano has signs of increased unrest above the known background
The Mount Spurr is constantly monitored due to its proximity to Anchorage, the most populous city in Alaska, said Haney. There are 11 remote seismic stations around Mount Spurr.

According to the observatory, primary dangers for the southern central Alaska communities during the eruptions on Mount Spurr are wide clouds and ash.
Volcanologists will monitor further increases in seismic activity, gas emissions and thunderstorm heating in order to indicate that an outbreak according to the observatory is imminent. The detection of volcanic tremors – a continuous shaking that can take a few minutes instead of short, small earthquakes – wants the level to be imposed, said Haney.
If the monitoring of data indicates that an outbreak is likely to be within hours or days, the observatory increases its alarm level to orange or red.
