Sometimes the atmosphere is not the only thing that makes noise. Lately, the Earth itself has been rumbling beneath our feet.
Across the globe, seismic activity is increasing, especially in the well-known Ring of Fire. This massive horseshoe-shaped zone wraps around the Pacific Ocean where tectonic plates collide.
In recent weeks, we have seen an uptick in volcanic eruptions and earthquakes from Alaska to Japan, from the Philippines to Chile. That leads to a fascinating question— does all this underground activity impact on the weather? The answer is yes. It certainly can.
Volcanoes have a remarkable relationship with the atmosphere. When one erupts, it can send huge amounts of ash and gas into the sky. If the eruption is powerful enough, the debris can reach the stratosphere, which is well above the layer where our usual weather takes place.
One of the key gases released during a major eruption is sulfur dioxide. When that gas rises high enough, it mixes with water vapor to form sulfate aerosols — tiny particles that act like tiny mirrors, reflecting sunlight away from the Earth. That reflection can cool the surface of the planet, not just in the immediate area but globally.
One of the best-known examples of this is the 1991 eruption of Mt. Pinatubo in the Philippines. It lowered the average global temperature by nearly one degree Fahrenheit for a couple of years. That may sound small, but in climate terms, it is a big shift.
Historical eruptions like Krakatoa in 1883 had similar effects. On a smaller scale, volcanic ash clouds can darken the sky, lower surface temperatures, and even change short-term rainfall patterns.
They also wreak havoc on aviation and can block out the sun for days in surrounding regions. Not every eruption cools the planet. It depends on the size of the eruption, how high the ash goes, and how much sulfur dioxide is released. Smaller eruptions or those that do not reach the stratosphere tend to wash out quickly in the rain and have little long-term impact.
So why should we care about the increase in activity now? When we see a global pattern of rising volcanic and earthquake activity, especially along the Ring of Fire, it is worth paying attention.
If one of the larger volcanoes, such as Shiveluch in Russia, Popocatépetl in Mexico, or even Mt. Rainier in the United States, were to erupt in a significant way, it could affect our climate. We might experience cooler temperatures, changes to the jet stream, or seasonal shifts in rainfall.
Volcanic cooling could disrupt agriculture, shift storm tracks, and influence everything from hurricane development to snowpack in the mountains. Earthquakes alone do not directly influence weather, but they are often a sign of tectonic stress that could trigger volcanic activity. They also remind us that our planet is dynamic, alive, and capable of change at a moment’s notice.
From my window, I am not just watching the clouds but also the quiet mountains and sleeping giants. When those mountains awaken, the atmosphere takes notice. Because when the Earth speaks, the weather often answers in kind.
