One of the things that brings anxiety to humanity is volcanoes. The Northeast Pacific’s most active volcano, the Axial Seamount, is about to erupt. This underwater volcano has been going through geological shifts for the past years and researchers state that something is cooking and it could potentially erupt soon in America. Should we be concerned? Are we in danger? Let us find out.
A brief background and history of the Axial Seamount volcano
According to a blog post, the underwater flamethrower has exploded three times in the last thirty years, blowing its stack in 1998, 2011, and 2015. In the meantime, several magma pools beneath the volcano were discovered by a recent study that was published in Nature. The 3,600-foot mountain’s recent surge in seismic activity, which is comparable to the tectonic overtures that preceded its last eruption a decade ago, served as the basis for the researchers’ most recent prediction.
We have also identified that, even though it is underwater, it has the ability to cause widespread disruption if it erupts, although other researchers state otherwise. Previous eruptions have caused danger and affected the ecosystem. Additionally, scientists and geologists are worried that if this volcano erupts, it will destroy marine creatures and underwater life. This could also have a negative impact on the surrounding regions.
The reasons why this volcano differs from others
Axial Seamount is not just another intriguing volcano or an underwater volcano; it is the most active submarine volcano in the Northeast Pacific. Also, different from the unusual and common land volcanoes that can be detected and analysed easily, this one is under deep water; therefore, detecting it and understanding what its next move is is quite challenging.
Another reason it stands out is its eruptive pattern. Take a look: magma accumulation and subsequent discharge have been the patterns of previous eruptions in 1998, 2011, and 2015. If this pattern continues, the next eruption could be due anytime from now. Of which, researchers are talking about the end of 2025; something could transpire.
Bill Chadwick also expressed,
“What’s leading us to talk about an eruption in the next year and by the end of 2025 is we’re almost fully reinflated to the level it was before the 2015 eruption. So, all these signs are pointing toward the final stages of the buildup to the next eruption.”
The potential significance of an eruption for the American coastline
Even though the Axial Seamount is located far below the surface, its eruptions could affect the shoreline of the United States. Massive volumes of water are displaced when magma is discharged, occasionally resulting in underwater landslides. Although geologists think there is little chance of a significant tsunami in Axial, these changes could cause tsunamis.
The impact on marine ecosystems and ocean currents is more worrisome. Sulphur and other gases could be released into the ocean after a large eruption, changing the water’s chemical makeup and perhaps harming marine life. If Axial’s activity reaches a critical point, it might damage Pacific Northwest fisheries, which depend on steady ocean conditions.
The race to comprehend and forecast upcoming eruptions
One of the difficult things with land volcanoes and underwater volcanoes like the Axial Seamount is that scientists cannot collect real-time data to have accurate predictions of what could happen next and when. Although land volcanoes are easier to predict or observe, to collect data from Axial, researchers must use deep-sea equipment and remotely operated vehicles.
The Axial Seamount is located at the interface of the Pacific and Juan de Fuca tectonic plates. Here, fresh ocean crust that has been ejected by the pressure of the clashing plates is slowly spreading out from the bulging seam. We hope that the knowledge we gain here will help us understand how nature functions in this area and can be applied to volcanoes around the world.
