The tephra deposits in the foreground at the eastern base of Chikurachki were emplaced during a major explosive eruption in 1986. The eruption began on 18 November and reached its peak on 20-21 November when maximum ash plume heights of 10-11 km were reported. Pyroclastic flows traveled down the ESE flank. On 22 November lava flow extrusion began and continued through to 7 December, descending to 560 m elevation on the SE flank.
