Aerial oblique view of Pu`u `O`o cinder-and-spatter cone

Aerial oblique view of Pu`u `O`o cinder-and-spatter cone, looking west. Visible in foreground are crater overflows that occurred chiefly in 1997, now armoring the east flank of Pu`u `O`o. The feature known as "crater vent" is the heavily fuming area in upper left of crater depression. Only scant fresh lava was visible in the crater vent when this photo (p0852) was taken January 30, 1988. Distance across crater is about 200 m (left to right).
