Increased Seismic Activity at Mount Spurr Raises Eruption Concerns

The increase in seismic activity is recorded in Mount Spur, which is a stratovolkano located 124 km west of Aankorezes, Alaska. In the last ten months, the activity seen in recent weeks has detected small earthquakes, with a noticeable increase. Reports suggest that the earthquakes, which were initially concentrated near the summit, have moved to the crater peak, a side vent that was previously burst in 1992 and 1953. Scientists suggest that it may indicate the movement of the magma under the volcano, possibly leading to an explosion. , The possibility of an explosion on the crater peaks is estimated at 50 percent, while the main pit of the volcano is less likely to explode.

Possible explosion landscape on mount spur

According For the Alaska volcanic observatory (AVO), the ongoing seismic activity can either explode or reduce without significant volcanic activity. Matt Honey, Scientist in AVO, told Live science earthquake pattern has intensified, with a shock now focused in an area about 3 kilometers below the slope. The innings aligns with previous explosions with crater peaks, which brought the ash plums to the atmosphere of 20,000 meters. Despite the similarity of past incidence, the volcanic disturbance seen in 2004 and 2005 did not result in the explosion, indicating that the increased earthquake does not always cause an explosive phenomenon.

Potential effect of explosion

If there is an explosion, dangers such as pyrocklastic flows, larhar and aspires can affect the surrounding areas. While no community is directly in the passage of potential lahahar or pyroquestic flow, air travel disruption may be important. The explosion of the 1992 pit explosion shut down the temporary closure of the Encourage airport and covered parts of the city in Ash. Given the current amount of air traffic passing through Alaska, a similar event can cause major disruption in transcontinental flights. Scientific situations are closely monitored, especially for long -term seismic shock signs, which may indicate that an explosion is adjacent.
