In Pu'u O'o,  the lava effusion, which began in late May, is continuing. After the passage of Pali, the 61g lava flow continue on the coastal plain towards the ocean.

His progress has decreased significantly between Tuesday and Friday, where she advanced from 90 meters. The lava front was on July 8 at about 1.1 km from the edge of the island, and the evacuation route, and on July 9, at noon, at about 1 km from the ocean. The night glow is visible on the active lava field, and the skylights above the Pali.

This map shows recent changes to Kīlauea’s East Rift Zone lava flow field. The area of the active flow field as of June 30 is shown in pink, while widening and advancement of the active flow as mapped on July 8 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray.  - doc. HVO

Compared with the lava flow known as June 27 flow that threatened the Pahoa area, the 61g flow poses no problems for residential areas.

The weakened risk to properties did not diminish this regarding observers: besides the danger of burns and exposure to gas, those of falls on uneven terrain and dehydration due to both the sun and heat warm soils should not be taken lightly, and require appropriate equipment (hiking boots, long pants, gloves, protective glasses, mask, and lots and lots of water)
