Topographic map of Veniaminof, showing the margin of the caldera (red dashed line) and the active cone within the caldera (black circle). The current eruption (June 2013) has produced a small lava flow (less than 1/2 mile long as of June 18) down the flank of the active intra-caldera cinder cone. Veniaminof's caldera is 5-6.8 miles in diameter.
