Global Volcanism Program | Image GVP-08094

The SW side of Concepción volcano has been affected by mass-wasting processes.  This 1992 photo shows the effects of many rockfalls, small landslides, and slow-moving flows of ash and cinders on the west and south flanks.  The SW gully has discharged a large amount of blocky and fine material since 1983, forming a fan (lower left) that by 1986 had engulfed and killed 500 sq m of mature forest.  Areas as far away as hamlets above the village of San José (8 km SW of the crater) were affected, and some homes had to be abandoned.  Photo by Franco Penalba, 1992 (courtesy of Jaime Incer).
