Concerns Rise Over Potential Eruption at Fentale Volcano Due to Increased Seismic Activity in Ethiopia

Fentale volcano in Ethiopia has experienced increased seismic activity, with earthquakes measuring between 4.3 and 5.1 in magnitude over recent days. Concerns have been raised about the possibility of a volcanic eruption due to shallow magma intrusion. Authorities advise local communities to prepare for potential evacuations, given the historical context of eruptions and the lack of a local seismic monitoring network.

Recent geological activity around the Fentale volcano in Ethiopia’s Main Ethiopian Rift has raised concerns regarding a potential eruption. A series of shallow earthquakes, ranging from magnitudes of 4.3 to 5.1, were recorded in the region over the previous days, with the most significant tremor occurring on December 29, measuring 5.1. This seismic swarm mirrors historical patterns of volcanic activity, as the last eruption was documented in 1820, marking the need for vigilance among local populations.

Volcanologist Tom Pfeiffer of VolcanoDiscovery emphasizes that the heightened seismic activity around the Fentale volcano, particularly the presence of a shallow magma intrusion, could lead to an eruption. This seismic uptick was felt widely, including in Addis Ababa, indicating that multiple quakes may go undetected due to the lack of a comprehensive local seismic network. Despite no immediate reports of damage or injuries, residents have expressed alarm, and authorities have advised on preparedness measures for possible evacuations. Furthermore, with over 3.4 million people residing within 100 kilometers of the volcano, the risks associated with increased volcanism pose significant threats to local communities.

The Fentale volcano, located at the northern end of the East African Rift System, is part of a tectonically active zone influenced by the divergent movement of the Nubian and Somali plates. Historical eruptions have produced extensive basaltic lava flows and resulted in significant local impact, including destruction recorded during a 13th-century eruption. The geological dynamics of the region include not only volcanic activity but also a history of earthquake swarms, as evidenced by previous events in the area, such as the 1989 Afar Triple Junction swarm.

The Fentale volcano is situated within Ethiopia’s Main Ethiopian Rift, a geologically active zone with a history of seismicity and volcanism, primarily due to tectonic movements. The region has experienced significant earthquakes and volcanic activities over the centuries, with the last noted eruption occurring in 1820. Geological evidence indicates that the Fentale volcano itself has a complex history of eruptions, with two confirmed Holocene episodes and several lava flows affecting the landscape. Resonating with the region’s tectonic activity, recent seismic manifestations suggest potential upward movements of magma, raising alarms about an impending eruption risk.

The series of recent earthquakes surrounding the Fentale volcano indicate a significant increase in seismic activity, highlighting potential volcanic eruption risks that necessitate close monitoring and community preparedness. Reports by experts suggest that increased magma intrusion beneath the volcano could escalate into an eruptive event, contributing to the urgency for local authorities and residents to remain vigilant. The historical context of the Fentale volcano’s prior eruptions serves as a reminder of the potential dangers the region faces, especially given the high population density nearby.
