M5.5 Earthquake Triggers Concerns Near Dofen Volcano, Ethiopia

On March 16, 2025, an M5.5 earthquake struck near Dofen volcano in Ethiopia’s Afar region at a depth of 10 km. Approximately 6,000 individuals felt severe shaking. The USGS issued a Green alert for potential fatalities and damage. Mass evacuations occurred following escalating seismic activity, with concerns regarding regional infrastructure, particularly the Kesem/Sabure Dam.

A significant M5.5 earthquake occurred near Dofen volcano in Ethiopia’s Afar region at 18:53 UTC on March 16, 2025. The quake, recorded at a shallow depth of 10 km, has been confirmed by both the US Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC). The earthquake’s epicenter was located approximately 46 km south of Awash and 55.5 km east of Dofen volcano.

About 6,000 individuals experienced severe shaking, while an estimated 30,000 felt moderate tremors. The USGS issued a Green alert for potential shaking-related fatalities and economic damage, indicating a low probability of significant casualties. Nevertheless, the structures within this region primarily consist of vulnerable types such as informal metal, timber, and adobe constructions.

Subsequent to the initial quake, a moderate aftershock measured M4.3, occurring south-southeast of Abomsa. The present seismic events are part of a seismo-volcanic crisis that began on December 22, 2024. This issue has included a series of notable earthquakes and the emergence of large ground fissures, raising alarms regarding the initial recorded potential eruption of Mount Dofen.

Following a previous M5.7 earthquake that led to large cracks, mass evacuations were executed, resulting in the displacement of over 60,000 people. Concerns regarding the Kesem/Sabure Dam’s structural integrity have surfaced, as it is designed to withstand quakes up to M5.6. With seismic activity exceeding this level, experts warn of potential flooding that could threaten hundreds of thousands of lives.

Mount Dofen, with an elevation of 1,151 meters, is situated within the tectonically active Main Ethiopian Rift. This area is highly susceptible to frequent seismic events and volcanic activity due to ongoing tectonic plate movements and magma intrusions.

In summary, a M5.5 earthquake near Dofen volcano in the Afar region of Ethiopia has raised concerns about significant aftershocks and potential volcanic activity. With thousands displaced and multiple vulnerabilities in local structures, the situation remains precarious. The integrity of the nearby Kesem/Sabure Dam is also under review due to the ongoing seismic threat, highlighting the need for continued monitoring and preparedness in this geologically active region.
