Mount Spurr is now active after being quiet for decades. The stratovolcano is located 81 miles west of Anchorage, Alaska. Years passed with barely anyone noticing the watchful slopes and snow on its summit. At the moment, scientists monitor the mountain carefully after noticing it may lead to a volcanic eruption.
During a single year, more than 3,400 earthquakes have been reported under Mount Spurr by the Alaska Volcano Observatory. There were weeks when more than a hundred tremors happened between February and March. This is evidence that magma is being pushed up from below the Earth’s surface.
There have been previous occasions when the volcano made the news. In 1992, there were three eruptions at Mount Spurr. As a result of the explosions, Anchorage was covered with ash, air travel was halted, and people suffered health issues. Many people who lived through this still recall the chaos.
Right now, people in Alaska are preparing for the next storm. People are purchasing masks, goggles, and air filters. Emergency kits are being packed. They wait and stay on alert to see what approach the volcano will take next. At the moment, we don’t know what the future will hold.

Many Earthquakes Lead to Concerns
The recent seismic activity at Mount Spurr is impossible to miss. According to AVO scientists, there have been thousands of tremors coming from the volcano in the past year. Usually, when the Earth experiences this type of seismic activity, it is a sign that magma is coming closer to the surface and could cause a volcano to erupt.
A quake happens when stress is put on the earth’s crust because magma rises through it. These earthquakes differ in their strength and location, but all of them indicate a serious issue. It is the same type of activity witnessed prior to the 1992 eruption.
Even though the volcano’s alert status is moderate, more attention is being given to monitoring it. Seismometers are capturing ground motion. Satellites are used by scientists to measure the shape of the volcano. An increase in sulfur dioxide is another possible sign that a volcano is about to erupt.
In 1992, the eruption blasted ash more than 12 miles above the mountain. Flights were canceled. The ash reached Anchorage, affecting areas such as residences, schools, and companies. Because of the pattern of earthquakes, experts suspect a similar volcanic eruption could occur again.
At that point, the region remains on full alert. Experts watch the monitors all day and will warn others if the situation changes.
Returning ashfall could risk people’s health.
People with breathing problems, including those with asthma, are at greatest risk from the effects of volcanic ash. After the 1992 volcano eruption, the narrow particles in the ash led to many people feeling and getting ill. Particles found in ash are hard and sharp, unlike the soft and easy-to-touch soot from fire.
Simply inhaling ash can cause irritation to the lungs, nose, throat, and eyes. These fumes can even cause asthma and many other breathing conditions to get worse. So, health experts say it’s important to stay safe in advance, even when no eruption has started yet.
As a result, lots of community residents are now wearing N95 masks and goggles. Certain people are covering windows and doors with insulating materials. There are also people who plan to remain indoors as soon as ash begins to fall.
Ash doesn’t just harm people. It is able to harm car parts, clog up engines, and pollute our water supply. It also causes reduced visibility due to the covering of windows.
Having some supplies at home can help you be ready for anything, say health officials. Staying at home, utilizing air filters, and wearing the right gear can really help. If people take the appropriate steps, many of the most harmful results of a volcano eruption can be minimized.
In the past, Mount Spurr has experienced eruptions that may give clues about future activity. In 1953, the volcano had its first eruption, and it had three more eruptions in 1992. Each time, what happened had serious and dangerous consequences. In 1992, ash from the eruption rose to over 12 miles in the air. Flights were canceled. Ash was dropped on Anchorage, covering buildings, schools, and businesses. Individuals were asked to remain indoors and not drive at all.
The location of the volcano increases the danger. Since it is across Cook Inlet, gusty winds can sometimes transport the ash across the water. During an eruption, Anchorage, Alaska’s biggest city, is still in danger.
Data from previous eruptions is being used by scientists to forecast upcoming ones. They analyze the features of volcanic ash, earthquakes, and gas that comes out. They are trying to figure out how the next eruption may occur.
Thanks to what has been learned in the past, China is better prepared. No one can say exactly when, but the signals are obvious. In the past, Mount Spurr has caused this problem, and it can happen again.
Communities Pay Attention As Scientists Monitor the Problem
People living in Alaska understand that natural hazards can happen. Each day, we deal with earthquakes, snowstorms, and wildfires. Even so, when a volcano makes its presence known with rumbling, many people look on.
Emergency officials and scientists are teaming up to provide information to the public. They are releasing safety tips and keeping people informed in real time. Communities are making plans for how to handle a volcano eruption.
The Alaska Volcano Observatory is constantly monitoring the volcano’s behavior. They rely on gas detectors, cameras, and information from satellites. Should the volcano show any sudden signs of activity, they share that information with everyone.
Currently, everyone seems a little cautious but calm. People in the area are keeping a close eye on things yet remain calm. Both schools and businesses remain open, but all are watching the news closely.
This careful balance is how people live in the area of a volcano. Individuals want to know what is going on. They’re also trying their best to protect themselves. Someone local commented, “To us, listening to what the ground says is important.”
The Calm Before the Eruption?
The surface of Mount Spurr is quiet, but there are indicators of increasing trouble below. A large number of earthquakes and observations of magma suggest that the eruption could happen. We can’t predict the moment, but people usually notice the warning signs well ahead of time.
Now that Alaska has access to up-to-date science and knows its surroundings well, it is more prepared. Action is being taken early as people become more aware of what is happening. If Mount Spurr does erupt, they will be well prepared for it.
The mountain is still, covered in white, but deep inside it feels a restless heart. Regardless of when it happens, we are all watching closely because it is such an important issue.
