Overview

• Published June 10, 2025 in Frontiers in Earth Science, the study led by Dr. Yuyu Li uses Veniaminof’s 2018 eruption data to build its predictive model.
• Researchers found that slow magma supply into a small, thermally warmed chamber suppresses ground deformation and seismic signals, enabling stealthy eruptions.
• Veniaminof has produced 13 eruptions since 1993 but only two offered clear warning signs, underscoring the hazards of undetected activity.
• To capture subtle eruption triggers, scientists recommend integrating borehole tiltmeters, strainmeters, fiber-optic sensing, infrasound arrays and gas emission monitors.
• The model offers a framework for assessing stealth eruption risks at similarly prone volcanoes worldwide, including Popocatépetl, Merapi and Stromboli.
