Last 24 hours at Kilauea summit: Molten lava probably exists at shallow depth within the new vent, but cannot yet be seen from the surface. Yesterday's overflight provided the best views so far of the incandescent vent throat dipping beneath at least 20 m (60 ft) of overhanging, crater filling flows (see images).
Definitions of terms used in the update: tephra: all material deposited by fallout from an eruption plume, regardless of size. ash: tephra less than 2 mm (5/64 inches). Previous updates sometimes used the term 'ash' loosely (without regard to particle size) where 'tephra' was more appropriate.
