The last recorded eruption of Reclus was in 1908, but local press reports in the 1980s and 1990s attributed earthquakes to volcanic activity at Reclus and Burney. Seismic activity was noted at Reclus in 1998 and 2003, and possible eruption phenomena were reported in 2008 in form of tephra deposition and cracks in the glaciers. In 2015, the Chilean SERNAGEOMIN announced that they would install an experimental surveillance system at Reclus. Ash from a future eruption of Reclus could be swept into the reservoirs of Néstor Kirchner Dam and Jorge Cepernic Dam on the Santa Cruz River, impacting their activity.
