Volcanic Activity Summary: On June 27, 2014, new vents opened on the northeast flank of the Pu‘u ‘O‘o cone that fed a narrow lava flow to the east-northeast. On August 18, the flow entered a ground crack, traveled underground for several days, then resurfaced to form a small lava pad. The sequence was repeated twice more over the following days with lava entering other cracks and reappearing farther downslope. In this way, the flow had advanced approximately 13.2 km (8.2 miles) from the vent, or to within 1.3 km (0.8 miles) of the eastern boundary of the Wao Kele o Puna Forest Reserve, by the afternoon of September 3. Overnight, lava did not appear to advance farther east within the crack system, but surface flows advanced about 100 m to the northeast. At the average rate of advancement of 250 m/day (820 ft/day) since July 10, we project that lava could reach the Kaohe Homesteads boundary within 5-7 days should lava resume advancing within the crack system.

Kaohe Homesteads is located between the Wao Kele o Puna Forest Reserve and the town of P?hoa in the Puna District of the County of Hawai`i.
