Strong and Shallow M5.5 Earthquake Hits Near Dofen Volcano in Ethiopia’s Afar Region
A magnitude 5.5 earthquake struck Ethiopia’s Afar region on March 16, 2025. The USGS reported it at a shallow depth of 10 km, causing significant shaking felt by thousands. It is part of an ongoing seismo-volcanic crisis linked to Dofen volcano, raising concerns about the structural integrity of local infrastructure, including nearby dams. Evacuations are ongoing due to secondary hazards from previous seismic activity.
On March 16, 2025, a strong earthquake measuring M5.5 struck the Afar region of Ethiopia, occurring at 18:53 UTC (21:53 local time). The quake’s depth was recorded at 10 kilometers (6.2 miles), as confirmed by both the United States Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC). The epicenter was located approximately 46 kilometers south of Awash and 63.8 kilometers south-southwest of Metahara.
An estimated 6,000 individuals experienced severe shaking, while 26,000 felt very strong vibrations, 14,000 perceived strong tremors, and 30,000 registered moderate shaking. The USGS issued a Green alert, indicating a low probability of casualties and economic damage, despite noted vulnerabilities in the region’s building structures, which include informal materials and adobe block construction.
This earthquake is part of a broader seismo-volcanic crisis affecting Dofen volcano since December 2024, characterized by a series of seismic events, ground fissures, and the emergence of a notable volcanic vent. Residents have faced significant challenges, including mass evacuations following an earlier M5.7 earthquake on January 4, 2025, which displaced over 60,000 individuals.
An aftershock, measuring M4.3, was recorded later the same day, 47 kilometers southeast of Abomsa. The situation raises concerns regarding the Kesem/Sabure Dam’s structural integrity, which was designed to endure earthquakes up to M5.6, but is now under strain due to ongoing seismic activity. Failure of the dam could lead to catastrophic flooding, threatening many lives.
Mount Dofen, part of the East African Rift System, is situated within a highly tectonically active area, marked by frequent earthquakes and potential volcanic eruptions. This ongoing geological activity underscores the need for continual monitoring and preparedness efforts in the region.
The M5.5 earthquake near Dofen volcano in Ethiopia’s Afar region highlights the ongoing seismo-volcanic crisis affecting the area. With significant population exposure and the potential for further seismic activity, authorities face pressing challenges regarding public safety and infrastructure stability. The risks pose a critical need for ongoing monitoring and preparedness to protect the vulnerable local communities.
