The 2001–2004 dome-forming eruption of Shiveluch volcano, Kamchatka: Observation, petrological investigation and numerical modelling
O Dirksen, MCS Humphreys, P Pletchov… - Journal of volcanology …, 2006 - Elsevier
There have been three episodes of lava dome growth at Shiveluch volcano, Kamchatka
since the Plinian explosive eruption in 1964. The episodes in 1980–1981, 1993–1995 and
2001–2004 have discharged at least 0.27 km3 of silicic andesite magma. A time-averaged
mean extrusion rate of 0.2 m3/s is thus estimated for the last 40years. Here the 2001–2004
activity is described and compared with the earlier episodes. The recent activity involved
three pulses in extrusion rate and a transition to ongoing lava extrusion. Estimated magma …
