East Lae`apuki lava delta, looking west. Large plume of steam, hydrochloric acid, tiny glass bits, and other material rises from a number of entries along leading edge of delta. Blue fume comes from skylight in lava tube that feeds the entries.
Closer view of East Lae`apuki lava delta. White area is salt-encrusted older flow on delta's surface. Shiny flow leading down from skylight is fresh, possibly still active. Note that it partly covers large crack (visible below blue fume); this will provide a good marker for renewed opening of crack.
Aerial view of East Pond Vent on floor of Pu`u `O`o's crater. One peak of spatter cone rises at upper edge of vent; other peak is largely hidden by fume about 7-8 o'clock from vent.
Spattering from East Pond Vent. Level of lava pond in vent is higher than it has been in some time, so spattering is readily seen. Bits of spatter recently cleared the rim of the vent and landed on the crater floor.
