Context: Ethiopia’s Mount Fentale volcano has emitted massive methane plumes, an unprecedented natural event with potential climate change implications.

About Mount Fentale:

• What Happened?

• Mount Fentale, located in northern Ethiopia, released large amounts of methane into the atmosphere starting January 31, 2025. The event was described as a “burp”, with huge plumes of methane escaping from underground gas deposits. This phenomenon was first detected via satellite monitoring and later confirmed by GHGSat.

• Why Is This Unusual?

• Volcanic activity typically emits carbon dioxide (CO₂) and sulfur dioxide (SO₂), not methane (CH₄). Methane is 28 times more effective at trapping heat than carbon dioxide over a 100-year period. The emission surpasses typical volcanic gas output, raising concerns over climate impact and greenhouse gas monitoring.

• Scientific Explanations:

• The methane release is likely due to magma movements opening underground gas pockets, rather than a surface eruption. Thermal anomalies detected via satellite in January suggest deep-seated geological activity.

• Climate and Environmental Concerns

• Methane is the second-largest contributor to global warming (11% of total greenhouse gases). Even short-term spikes in methane levels can intensify climate change effects. Highlights the need for improved global methane tracking, both from natural sources and human activities.
