By early December, the length of both lava flow was about 10 km. Currently, the upper crack stopped working. At the bottom of the fissure formation of cinder cones and the outpouring of the lava flow, the length of which is about 20 km and height of the front of the 8-10 m

Collapse Expand I don't have numbers, but my guess is the volume is still pretty low.
< 0.1 cubic kilometers as a max? Very hard to tell.

#Tolbachik volcano, Kamchatka. Volcano is erupting 1200 tonnes of lava every second.

During the Great Tolbachik Fissure Eruption in 1975, the volcano spilled on average 40 cubic metres of magma per second while at present its productivity is about 400 cubic metres or 1,200 tonnes per second.
Hmm. Let's check real total volume for today.
If data above true then:
400 cubic meters per second õ 3600 sec in hour x 24 hour x 15 days of eruption = 518400000 cubic meters =
518 cubic kilometersIt's volume of FIVE Tabmora's 1815 year eruption (VEI 6 - 100 km3 [

or half of volume (estimates) of great Yellowstone eruption (VEI 9 - 1000 km3).
But other data above force doubt on this assessment:
10-20 kilometers of lava flow length =>
10000-20000 meters of lenhth x (I guess) width of flow about 100-200 meters õ 8-10 meters of thickness = min 8000000 cubic meters max 40000000 cubic meters.
It means
from 8 to 40 cubic kilometers. In any case not small
I guess this estimate more realistic.
