Mount Spurr has begun to stir after decades of silence. This 11,070-foot stratovolcano sits 81 miles west of Anchorage, Alaska. For years, it remained quiet—its snow-covered peak barely drawing attention. But now, scientists are watching closely as the mountain shows signs of a possible volcanic eruption.

The Alaska Volcano Observatory (AVO) has recorded more than 3,400 earthquakes under Mount Spurr in just one year. Between February and March, over 100 tremors occurred each week. These earthquakes suggest magma is pushing upward beneath the surface.

This isn’t the first time the volcano has made headlines. In 1992, Mount Spurr erupted three times. The explosions sent ash clouds over Anchorage, disrupted air travel, and caused health problems. The memory of that chaos still lingers for many residents.

Today, Alaskans are preparing once again. They’re buying masks, goggles, and air purifiers. Emergency kits are being packed. Everyone is listening for updates, waiting to see what the volcano will do next. For now, it’s a tense and uncertain time.

A Surge of Earthquakes Sparks Concern

Mount Spurr’s recent earthquake activity is impossible to ignore. According to AVO scientists, the volcano has produced thousands of tremors over the past year. This kind of seismic pattern often signals magma movement deep below ground and could lead to a volcano eruption.

Each quake represents stress in the earth’s crust as magma forces its way upward. These quakes vary in size and depth, but together they paint a troubling picture. They match the kind of activity that occurred before the 1992 eruption.

Although the volcano’s alert level remains moderate, monitoring has increased. Seismometers are capturing ground motion. Scientists are also using satellites to look for changes in the volcano’s shape. Rising levels of volcanic gases, such as sulfur dioxide, could also indicate an eruption is near.

Back in 1992, the volcano sent ash more than 12 miles into the sky. Flights were canceled. Ash fell on Anchorage, affecting homes, schools, and businesses. The current pattern of quakes makes experts think a similar volcanic eruption could happen again.

Until then, the region remains in a state of watchful waiting. Researchers continue their 24-hour surveillance, ready to sound the alarm if needed.
