Mount Fentale in Ethiopia is experiencing seismic unrest following rare methane emissions detected on January 31, 2025. Although methane levels have decreased since February 9, a magnitude 6.0 earthquake increased concern among scientists and locals. The ongoing geological activity has displaced approximately 80,000 residents and warrants continued monitoring for potential eruptions.
Ongoing seismic activity near Mount Fentale, Ethiopia, follows the detection of significant methane emissions by satellites on January 31, 2025. While emissions have decreased since February 9, a magnitude 6.0 earthquake on February 14 has kept scientists on high alert. Methane emissions, typically rare from volcanoes, were identified as originating from the volcano’s crater, with an estimated discharge of 58 metric tonnes per hour.
The monitoring was conducted using a combination of the Sentinel-5P TROPOMI satellite and GHGSat’s high-resolution sensors, which aim to track changes in greenhouse gas emissions. Ilse Aben from SRON remarked on the unexpected nature of these findings, noting the rarity of such large methane emissions from volcanic sites. Experts believe that the methane may result from shallow geothermal activities rather than direct magma interactions.
Recent satellite imagery has revealed a subsurface dike extending roughly 50 km toward Dofen volcano, suggesting a complex geological framework beneath the surface. Local monitoring has reported continued seismic swarms and ground deformation; however, a consistent decline in methane emissions has been observed. Despite these developments, the potential for volcanic eruptions remains uncertain.
The instability around Mount Fentale has led to the displacement of approximately 80,000 residents, with gas emissions and steam vents observed but no confirmed eruptions yet recorded. Ongoing assessments are evaluating the risks of potential eruptions from Fentale, Dofen, or new vents. The volcanic complex, characterized by an elliptical summit caldera, consists of various geological formations, with notable activity recorded historically as far back as the 13th century.
Thermal anomalies and gas plumes have recently been detected, indicating the region’s continued geological activity. Following earlier seismic events in early 2025, which had already displaced tens of thousands, authorities continue to track the area’s seismic hazards to protect local communities. Historical eruptions have underscored the need for constant monitoring as volcanic threats evolve in this dynamic environment.
The ongoing seismic unrest at Mount Fentale highlights the complexity of its geological activity, including unusual methane emissions and significant earthquakes. Scientists remain vigilant as they assess risks linked to potential eruptions and the implications for local communities, who have already faced substantial displacement due to these geological phenomena.
