Abstract Volcanic ash poses diverse and widespread hazards. Hybrid silicic volcanism – concurrent lava effusion and explosive ash venting – may constitute a significant but poorly quantified source of ash, so far only documented from a small number of eruptions, most notably the 2011–2012 eruption of Cordón Caulle (Chile). From that eruption, veneers of ash found welded on lava fractures have been attributed to the hybrid activity.
