by Mount Spurr in Alaska – rise of approximately 3,370 meters or 11,070 feet above sea level – can be about to burst out, with the number of small and recent earthquakes in the area now in the thousands.
Volcaan seismologist Matthew Haney, from the Alaska Volcano Observatory in Anchorage, Julia Jacobo told ABC News that the chances of an eruption are now around 50-50. That is after a noticeable increase in activity in the past 10 months.
Because the volcano is only 130 kilometers or 80 miles west of Anchorage – population 286,075 – there is a real chance of life. The city can be dressed in a dust cloud if there is an eruption, as happened in the past.
The video below shows the consequences of an eruption from 1953 from the same volcano, which shot an ash cloud more than 10,000 meters above sea level. There are images of people who sweep ashes of their vehicles and a snapshot of a head of the Anchorage Daily News That reads’ city ‘from Graven’. No deaths were associated with the eruption:

“Unrest continues on Mount Spurr, with countless small, shallow volcanic earthquakes that are detected under the volcano,” explains a recent volcano message from the United States Geological Survey (USGS).
“Earthquakes are under the north side of the Spurr Summit ventilation opening in the past day.”
The image below shows the steady increase in earthquakes that gather in the region, as well as their distance to the volcano.
The last eruption of Mount Spurr was actually three eruptions, which took place in a few months in 1992. The airport in Anchorage was forced to close to 20 hours because of the cloud of dust and ash that enveloped the city, but happy.
A single fatal exit was reported – from a heart attack caused by the creation of Asval – as well as a few millions of dollars damage. Then, like now, there were a few months of activity structure.
In addition to the small earthquakes, scientists have noticed the volcano with about 6.4 centimeters (2.5 inches), according to Haney – another sign that something is built under the surface, ready to blow.
However, it is not yet entirely time to take emergency measures. Similar rumors of Mount Spurr were recorded in 2004 and 2012, but were not followed by eruptions – and this could be a different similar scenario.
Moreover, the USGS experts say more seismic activity than we have seen so far, would be expected before an eruption, including around the fumarols or ventilation openings in the rock. Hopefully a lot of advance warning will be given if an eruption is about to happen.
“Based on earlier outbursts, changes to the current activity in the earthquakes, earth deflection, Summit Lake and Fumaoles would be expected when magma started to get closer to the surface,” says the USGS.
“That is why it is very likely that if there was an eruption, this would be preceded by extra signals that the Voorwaarschuwing would make possible.”
Volcanologists are now very closely monitoring Mount Spurr to try to get a better idea of what happens deep in the rock. As we know from very recent history, these eruptions can be monumental.
