Scientists are on a high alert after Thursday three American volcanoes rose, which suggests that eruptions can be imminent.
The US Geological Survey (USGS) placed Alaska's Great Sitkin on 'Watch' because it is 'raised or escalating unrest' and the Mount Spur of the State is under 'Advice' after signs of unrest.
Lava started to break out slowly in the Summit crater from Great Sitkin Volcano this week and small earthquakes were detected last day.
Mount Spurr, located in the Tordrillo Mountains about 80 miles from Anchorage, has also experienced an increase in seismic activity in the last 10 months. Scientists warned that it has a 50-50 chance to break out soon.
Hawaii's Kilauea is also under 'Watch' after cracking earlier this week Ninth episode of activity since December 23.
The volcano released a huge stream of lava on Tuesday and shot it more than 300 feet in the air.
While Kilauea is that Located in the remote Hawaii Volcanoes National Park on the Big Island, produced the latest eruption gas, ash and wind blown shards of volcanic glass that can be dangerous for human health.
The activity of the volcano was located from Friday morning. But experts say that it will probably burst out again within the next three to six days.
One of these volcanoes, Kilauea, broke out earlier this week and spit hot lava hundreds of foot in the air
Until now, no residential areas have been threatened by the lava flows of Kilauea
The USGS uses a national volcano warning system for characterizing circumstances (silent, unrest, outburst) in American volcanoes.
The codes include 'normal', '' advice ',' Watch 'and' warning ', which are also shown in colors: green, yellow, orange and red.
The US is the home base of 169 active volcanoes spread by Alaska, Hawaii, the Pacific Northwest, Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
Each volcano is followed by the USGS that looks at seismic activity, earth deformation, volcanic gases, thermal emissions and changes in water levels and chemistry.
And those factors were sufficient to place three volcanoes under increased reports.
Although Mount Spurr shows signs of raised unrest, it is not yet actively outlined.
Since the earthquakes started for the first time in April 2024, their rate has risen from an average of 30 per week to an average of 125 per week, which is underway at the beginning of October.
Experts from the Alaska Volcano Observatory (AVO) believe that this seismic activity is powered by new magma that runs under the volcano, a sign that an eruption could be imminent.

Mount Spurr is 77 miles from Anchorage, Alaska. An increase in seismic activity in the past 10 months has scientists who are alert to an imminent eruption
If Mount Spurr does blow, this explosive plums of ash, destructive mud flows that are called Lahars and avalanches of hot gas, ash and rock are called pyroclastic flows, which would run through the volcano on more than 200 mph.
Fortunately there are no communities within the potential path of pyroclastic streams or Lahars from Mount Spurr.
But the amount of axis that would come out of this volcano could pose a threat to human health, causing breathing difficulties and releasing toxins related to cancer.
Great Sitkin, which is located on the Western Aleutian islands, was elevated to a higher risk after minor earthquakes and steaming of his top crater.
This volcano broke explosively in May 2021 after a series of earthquakes underneath.
The eruption sent a feather of axle and gas 15,000 feet in the air, and this ash cloud led the USGS to upgrade the threat level of Great Sitkin to a 'warning' and to code his air trial risk as an urgent warning indicates aircraft That overhead fly.
Volcanic ash particles are angular and sharp enough to close jet engines, so experts warn pilots when a volcano is an active threat.
Two months after this eruption, Great Sitkin Lava started to process, when melted rock steadily from a volcano that is not accompanied by an explosive event.
Since then, this volcano leaks lava, but the recent underlying earthquakes that are discovered underneath suggest that another violent eruption could loom.
Fortunately, this island volcano is surrounded by water and is in a remote location, so it is unlikely that the lava flows threaten human lives.
But just like Mount Spurr and Kilauea, as and gas produced by large Sitkin can be dangerous for human health when it is blowing in communities.
Kilauea is the only one of the three who has been really active this week and released more than 22 hours of lava fountains on 12 February.
“Last night, several lava flows continued to flow slowly on the floor of HalemaÊ»umaÊ»u and other glowing areas remained visible on the crater floor, as recently erupted Lava continues to cool,” said the USGS Thursday.
'The North Vent stays at night Degas and glowing, indicating that magma remains vented in ventilation at relatively shallow levels.
