View looking northwest shows two spatter cones erupting on the south flank of Pu`u
`O`o:
- Spatter cone in middle left of photograph
- Small cone just south of Pu`u `O`o in center of
photograph. This cone fed many short
pahoehoe flows and two `a`a flows that advanced 4 km southeastward.
Note that the flows are spilling over the lip of a small perched pond of
lava right of the active vent (click on image to see more detail).
