Weekly Report (18 June-24 June 2014)



53.589°N, 159.15°E; summit elev. 2899 m

All times are local (unless otherwise noted)

KVERT reported that, during 14-19 June, satellite images over Zhupanovsky detected gas-and-steam plumes with discrete ash plumes up to 4.5 km (14,800 ft) a.s.l. drifting up to 70 km SE and NW from the volcano. Satellite images detected a thermal anomaly on 14-15 and 17-19 June. The Aviation Color Code was raised from Yellow to Orange.

Tokyo VAAC reported ash plumes during 18-20 June drifting NW and later NE. Plume heights were in range of 3,000-8,500 m (9,800-28,000 ft) a.s.l.

Geological Summary. The Zhupanovsky volcanic massif consists of four overlapping stratovolcanoes along a WNW-trending ridge. The elongated complex was constructed within a Pliocene-early Pleistocene caldera whose rim is exposed only on the eastern side. Three of the stratovolcanoes were built during the Pleistocene. An early Holocene stage of frequent moderate and weak eruptions from 7,000 to 5,000 years before present (BP) was followed by a period of infrequent larger eruptions that produced pyroclastic flows. The last major eruption took place about 800-900 BP. Recorded eruptions have consisted of relatively minor explosions from Priemysh, the third cone from the E about 2.5 km from the summit peak.
