Satellite data analysis by the MIROVA team indicated that thermal anomalies over Fentale crater were visible during 13-14 January and progressively increased in size at least through 0020 on 21 January (local time). No cause of these anomalies has been identified. A visible satellite image showed a possible gas plume over the crater. A 14 January news article stated that the Fentale crater typically hosts a small lake and that billowing plumes rise above the summit. The article also noted that 10,000 people evacuated from Seganto and possibly a total of 54,000 had been evacuated from higher-risk areas. The earthquakes damaged schools, buildings, a factory, and roads.

Seismicity and deformation data acquired from satellite radar images indicated that a magmatic intrusion began in late September 2024 in the Afar Region between the Fentale caldera and Dofen volcano. Interferograms, which show upward and downward land movement using sequenced satellite radar data, indicated that a magmatic intrusion aligned along the central to northern part of an axis connecting these two locations began in late September 2024, according to the UK Centre for Observation and Modelling of Earthquakes, Volcanoes and Tectonics (COMET). Many felt earthquakes M 4 and above were associated with the intrusion. Data from 18 October indicated that the intrusion had slowed or paused. A second phase of the intrusion occurred during the end of 2024. An interferogram processed and interpreted by the Universitas Insan Pembangunan Indonesia (UNIPI) group in support of the Addis Abeba University showed very clear ground movement (over 40 cm of uplift) along almost the entire axis from Fentale to Dofen during 17-29 December.

Seismicity continued to be elevated in the region at least through 4 January and was likely associated with the intrusion according to the Ethiopian Geological Institute. A M 5 on 29 December located near Awash Fentale caused the collapse of more than 30 homes and cracks in roads and the ground in the Dulecha and Awash Fentale districts. On 3 January footage of increased activity at a geothermal area near Dofen was reported by news sources. The video showed water, sediment, and rocks being vigorously ejected above vents; the activity was non-volcanic in origin though it increased fears among residents that is was connected to the intrusion and potential volcanic activity. At least 10 earthquakes were recorded during 3-4 January with the largest, a M 5.8, occurring on 4 January. The Ethiopian Geological Institute reported that thousands of people had evacuated to other areas in the region.

The forested lava flow (left foreground) was erupted on the caldera floor of Fentale volcano in 1820. This view looks from the NE. The walls of the 3 x 4 km summit caldera are up to 500 m high. During the 1820 eruption, basaltic lava flows were also extruded onto the Main Ethiopian Rift from a 4-km-long fissure on the south flank.

A vertical aerial photo of the Quaternary Fentale volcanic complex, lying along the main Ethiopian rift zone, has a prominent summit caldera and lava flows along its flanks. The 3 x 4 km caldera with steep-sided walls up to 500 m high is elongated perpendicular to the direction of the regional fissures of the Ethiopian Rift. Note the recent rhyolitic obsidian lava flow to the NE (upper right) marked with curved flow ridges. The dark lava flow on the caldera floor was erupted in 1820.

The caldera of Fentale volcano, also known as Fantale, is seen in a fish-eye lens view from the NE rim and has walls up to 500 m high. Welded pyroclastic flow deposits accompanied the 2.5 x 4.5 km summit caldera formation. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift and post-caldera vents occur along the same orientation. Trachytic and obsidian lava flows were emplaced onto the caldera floor. More recent lava flows were erupted in the caldera and on its flanks in 1820.

Fentale, also known as Fantale, is the stratovolcano seen here from the Ethiopian Rift. Fentale lies at the N end of the main Ethiopian Rift and consists primarily of rhyolitic obsidian lava flows with minor tuffs. Welded pyroclastic flow deposits were emplaced when the 2.5 x 4.5 km summit caldera formed. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift, and post-caldera vents occur along the same orientation.
