Alaska's Mount Edgecumbe, a dormant volcano near Sitka, has suddenly come to life with a startling increase in seismic activity. The US Geological Survey (USGS) reports over 100 earthquakes beneath the volcano since April 2022, prompting officials to raise the alert level.
Why the Sudden Concern?
While Mount Edgecumbe last erupted 800 years ago, the recent swarm of tremors – including a magnitude 4.1 quake – suggests magma might be moving deep underground. 'This many earthquakes under a volcano is always cause for attention,' explains USGS volcanologist Dr. Cheryl Cameron.
What Would an Eruption Look Like?
Experts believe any eruption would likely be:
- Explosive, creating ash clouds dangerous to aircraft
- Localised, with lava flows contained near the summit
- Preceded by further earthquake swarms and ground deformation
The Alaska Volcano Observatory is closely monitoring gas emissions and ground swelling using satellite technology. While no immediate eruption is predicted, the situation remains volatile.
Potential Impacts
An ash plume could:
- Disrupt trans-Pacific flight paths
- Affect air quality in nearby communities
- Damage local fisheries and wildlife
Residents are advised to stay informed through official channels as scientists continue round-the-clock monitoring of this awakening giant.
