The weakly explosive activity in May to June 1971 from the new explosion crater high on the eastern side of Etna produced a pyroclastic fall deposit which is very poorly sorted on the crater rim, but is well sorted farther away. Grain-size parameters are given for 47 sieved samples, seven of which were collected from the ash-fall during the eruption. The initial strombolian-type activity soon changed as pre-existing pyroclastic debris slid into the crater, and thereafter the ejecta included much non-juvenile material derived from this debris. The ash fell in the form of small damp flocculated clumps, but as it dried out much of the dust-grade material was blown away by the wind. Such dust may account for much of the loess-like soil found on the vegetated lower slopes of Etna.
