Surface flows remain active on the pali and coastal plain, but have not made significant progress towards the ocean. On today's field visit, the closest flows to the ocean were about 2 km (1.2 miles) from the water. This image shows a pāhoehoe breakout at the flow front, with a rigid ropy section of crust being carried forward by the flowing lava beneath it.
