Molten lava flows through tubes from the vent to the ocean.
Eruption rate has been about 500,000 cubic meters per day during the past few weeks. At the coast the lava continues to build a bench seaward from the land's edge, with small cones constructed whenever the hot lava interacts explosively with seawater. The flow field expanded slowly until, in July, lava reached the sea. The supply of lava to these flows became restricted to tubes, and surface flow activity diminished greatly. The pit is about 30 m in diameter, and from its cauldron lava froths and sloshes.
