Underwater Volcano Near Oregon Predicted to Erupt This Year

An underwater volcano located approximately 300 miles off the coast of Oregon is forecasted to erupt by the end of the year, according to volcanologists closely monitoring the situation. The Axial Seamount, situated along the Juan de Fuca Ridge at a depth of 4,900 feet, has shown signs of volcanic activity, although experts indicate that an eruption does not appear to be imminent.

The Axial Seamount is notable for being the most active submarine volcano in the northeast Pacific. Over the past three decades, it has experienced three eruptions: in 1998, 2011, and 2015. Researchers from Oregon State University, including volcanologist Bill Chadwick, are closely observing inflation patterns in the volcano, which can indicate impending eruptions.

Current Monitoring and Predictions

Chadwick confirmed in a recent interview that the forecast for an eruption remains valid, stating, “Our forecast of an eruption at Axial Seamount by the end of the year still stands, but I have to say nothing looks imminent.” Despite the ongoing monitoring, indications such as inflation levels suggest a complex situation. As of January, the volcano reached inflation levels comparable to those seen before its last eruption in 2015. However, as of July, there has been a gradual decrease in the rate of inflation.

The monitoring process is extensive, involving seismic activity analysis through instruments and cables extending from the U.S. coastline. Notably, in June, over 2,000 earthquakes were recorded in a single day near Axial Seamount, which is a potential indicator of volcanic unrest. Additionally, a recent tsunami wave caused by an 8.8 magnitude earthquake near Russia’s Kamchatka Peninsula triggered automated alerts designed to notify researchers of possible eruptions, although no actual eruption occurred.

Safety and Scientific Insight

Despite the volcano’s activity, experts assure that there is no immediate threat to human life or property. The U.S. Geological Survey states that due to the Axial Seamount’s significant depth and relatively gentle lava flow, there is minimal risk to ocean travel or coastal communities. Chadwick emphasized that “for the size of eruptions we’ve seen in the last 20 years… if you were on top of it on a boat, you would never know it.”

The next eruption, while not posing a threat, is expected to provide valuable insights into volcanic behavior. Researchers hope to enhance their understanding of eruption triggers through the ongoing monitoring efforts. Chadwick noted, “We can only wait and see, but nothing seems imminent at the moment since the rate of unrest keeps wavering.”

As the year progresses, scientists remain vigilant in their studies of the Axial Seamount, aiming to unravel the complexities of underwater volcanic activity and its implications for geological research.
