Continued Seismic Activity and Methane Emissions at Ethiopia’s…

Mount Fentale in Ethiopia is experiencing ongoing seismic unrest, with significant methane emissions detected on January 31, 2025. Following a decrease in methane emissions, a magnitude 6.0 earthquake occurred on February 14, prompting concerns among scientists and local residents. The geological complexities and potential for volcanic activity necessitate vigilant monitoring and assessment of risks to the surrounding communities.

Ongoing seismic unrest continues at Ethiopia’s Mount Fentale, following the detection of rare methane emissions detected on January 31, 2025. While emissions have decreased since February 9, seismic activity remains high, evidenced by a magnitude 6.0 earthquake on February 14. This combination has prompted scientists and residents to stay vigilant regarding the potential risks.

Significant methane emissions were identified via the integration of data from Europe’s Sentinel-5P TROPOMI satellite and GHGSat’s sensors, revealing an unusual volcanic gas composition where carbon dioxide and sulfur dioxide typically dominate. The emissions were traced to Fentale’s crater, with an estimated release of 58 metric tonnes per hour.

Ilse Aben, Senior Scientist at SRON, expressed surprise at the magnitude of the methane emissions, noting the rarity of such findings. Experts suggest these emissions could arise from geothermal activity underneath the volcano rather than being a direct result of magma degassing, indicating complex geological processes at play.

In addition, a subsurface dike, identified through satellite imagery, extends about 50 km away from Mount Fentale towards Dofen volcano, reflecting the seismic complexity in the region. Recent data confirm ongoing ground deformation and seismic swarms, which denote heightened volcanic activity, despite a reported decline in methane emissions since early February.

The February 14 earthquake heightened concerns as it marked a significant event in the context of increased seismicity since December 2024. The disturbances have displaced approximately 80,000 residents from affected areas, with scientists monitoring for possible volcanic eruptions that may involve Fentale, Dofen, or new geothermal vents.

What makes Mount Fentale notable is its unique geological structure, which includes a prominent elliptical summit caldera. Historical data shows that the last confirmed volcanic eruption occurred in 1820 CE, with significant past activity in the 13th century that damaged local infrastructure. Recent monitorings, like thermal anomalies observed from January 13 to 21, 2025, indicate that the region remains active and prone to disturbances.

Overall, the ongoing situation at Mount Fentale is a reminder of the dynamic interactions between geothermal systems and volcanic activity, highlighting the importance of satellite technology for real-time monitoring. Scientists continue to assess risks and implications for local communities amidst the seismic unrest affecting the region.

Mount Fentale in Ethiopia remains under significant seismic unrest and unusual methane emissions. Despite some decline in methane levels, ongoing seismic activity—including a magnitude 6.0 earthquake—poses a potential threat to local communities. The geological complexities of the area underline the necessity for continuous monitoring and risk assessment by scientists in response to evolving conditions.
