In Kilauea, the collapse of much of the wall surrounding the Pu'u O'o lava lake was overshadowed by the plethora of lava flows that spread to the upper portion of the lava field and on the Pali Pulama in recent days.
On February 20, numerous breakouts are reported to the east, as well as a strong effusion on 800 meters sector west ... which could revive the entries in the ocean if it continued.
On February 23, a flow came into the park boundaries, in two main arms, tending to merge.
