Summit Dome: 51°35' N, 157°20' E, summit elevation 1953 m
During Holocene, several extrusive domes formed in the summit part of the volcano, each sending a mantle of debris downslope. In addition, several explosive eruptions of Zheltovsky are known: one of them happened between 3 and 4 ka BP and produced black cinders of basaltic andesite composition; another produced a large andesitic block-and-ash flow and minor fallout ~500 yr BP (Fig.3); and, finally, one of the most recent eruptions presumably happened in the 19th century and produced fallout consisting of heavy sub-rounded basaltic lapilli rich in allivalite and eucrite inclusions. Both latest eruptions caused large lahars, which traveled towards the Pacific coast.
Holocene products of Zheltovsky are low-potassic basalts-andesites.
