Overview

Reclus, the source of several Patagonian Holocene tephra layers, was recognized to be an independent volcanic edifice in 1987. The volcano consists of a large dacitic pyroclastic cone with a crater about 1 km in diameter. As many as six tephra layers overlie a peat layer dated at 3,780 years before present.

Research has also revealed evidence for eruptions in the 19th and early 20th centuries.

    Regional Volcanic Activity
    The South America Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

    About the Photo

    Amalia Glacier flows around the northern flank of Reclus in the Southern Patagonia Ice Field, shown in this 27 February 2018 PlanetScope satellite image (N is at the top; this image is approximately 8 km across). The flanks are heavily eroded and there is a landslide deposit from the northern flank on the glacier surface.
