A mysterious, highly active undersea volcano near California could erupt later this year. What scientists expect

Scientists predict that Axial Seamount, the most active undersea volcano near California, could erupt by the end of 2024, based on a pattern of seafloor inflation. While the eruption poses no tsunami risk due to its non-explosive nature similar to Hawaiian volcanoes, it could impact local sea life and scientific equipment. Researchers are closely monitoring Axial Seamount, the best-monitored underwater volcano globally, hoping to refine eruption prediction methods applicable to more hazardous volcanoes.

Analysis

Scientists anticipate the Axial Seamount, an active undersea volcano approximately 700 miles northwest of San Francisco, could erupt by the end of 2024. This prediction is based on observed patterns of seafloor inflation; the volcano has previously erupted in 1998, 2011, and 2015, with the 2015 event being successfully forecasted seven months in advance using similar inflation data. Current inflation rates, which resumed in late 2023 and have been steady in 2024, suggest an eruption is likely by year-end, although current seismic activity does not indicate an imminent event. Importantly, Axial Seamount's eruptions are characterized by oozing lava, similar to Hawaiian volcanoes, and are not explosive, posing no tsunami risk to California, Oregon, or Washington. The eruption is also not expected to trigger a major earthquake on the Cascadia subduction zone. While the eruption could damage scientific equipment and impact local seafloor ecosystems directly buried by lava, it is not anticipated to affect surface marine life or be noticeable to onshore populations. The primary significance of this event lies in its scientific value; Axial Seamount is the world's best-monitored underwater volcano, and its frequent, patterned eruptions offer a crucial opportunity to refine volcanic eruption prediction methodologies, potentially benefiting the forecasting for more hazardous terrestrial volcanoes. The current forecast is described by researchers as an ongoing experiment in predictive science.

Key Decisions for Investors

• The predicted eruption of Axial Seamount carries negligible direct market impact and poses no immediate threat to coastal economies or infrastructure, thus not warranting specific portfolio adjustments based on this event alone.
• Investors should differentiate this localized, non-explosive undersea volcanic event from broader seismic risks in the Pacific Northwest; the Axial Seamount eruption is not anticipated to trigger tsunamis or significant earthquakes affecting populated areas.
• While this specific event does not present direct investment opportunities, the advanced monitoring and predictive science surrounding Axial Seamount underscore long-term advancements in geological hazard assessment technologies, which could have implications for sectors involved in risk management and scientific instrumentation.
