The ocean entry has expanded to the southwest through a series of lava "ooze-outs" from the southern flow margin that organized into an incipient channel. As of this morning, the flow margin was in or at the edge of Isaac Hale Park, approximately 175 m (575 ft) from the Pohoiki boat ramp. Unfortunately, the view was obscured by laze (the smaller plume below the larger laze plume) during the overflight.

Kīlauea summit

A collapse event occurred at the summit of Kīlauea this morning (July 24, 2018) at 6:41 a.m. HST, releasing energy equivalent to a magnitude-5.3 earthquake, which is similar to that released by previous collapse events. In this video, watch as today's event unfolds from the perspective of HVO's live-stream camera. At 6:41:08 (time stamp at upper left), a small tree along the right margin of the video begins to sway. At 6:41:10, a pressure wave passes through the steam plume in the crater, and light is reflected back to the camera (highlights the passage of the expanding sound energy through the air. At 6:41:11, a rockfall begins on the South Sulphur Banks, a distant light-colored scarp on the left.
