Lovely pictures.

I especially liked the red dot on Tolbachik which appears to be a skylight type lava lake,(with lava flowing beneath and emerging @ another vent as a flow with a window of molten lava continually replenished by turbulence in a former crater open to the air traversed by a fissure).

The much vaunted slowly extruding lava flow on the NE.flank of the Shiveluch lava dome is difficult to see in the pic & appears to be a "blob" type flow.

Have a nice day: Ag
