The summit lava lake today was at a relatively low level, about 65 meters (210 feet) below the Overlook crater rim, associated with summit deflation. Spattering was active along the lake margins. This photograph shows overflows from April and May (dark lava in bottom portion of photograph) covering the floor of Halemaʻumaʻu Crater. Photo taken Thursday, July 23, 2015 courtesy of USGS/HVO

Pele’s hair covers the roadside along Crater Rim Drive, next to the HalemaÊ»umaÊ»u parking lot, in an area of HawaiÊ»i Volcanoes National Park closed to the public due to proximity to the summit lava lake. The Pele’s hair (long strand of volcanic glass) is emitted from the lava lake and carried upwards by the rising gas plume, and then drifts downwind.

KÄ«lauea’s summit lava lake level remained fairly steady at 51 m (167 ft) below the vent rim until July 21, when the level dropped in response to summit deflation to about 65 m (210 ft), where it remained as of July 23.

KÄ«lauea’s East Rift Zone lava flow continues to feed widespread breakouts northeast of PuÊ»u ʻŌʻō. Active flows are slowly covering and widening the flow field, but remain within about 8 km (5 mi) of PuÊ»u ʻŌʻō.

One earthquake was reported felt on the Island of Hawai‘i this past week. On Friday, July 17, 2015, at 7:38 p.m., HST, a magnitude-2.6 earthquake occurred 6.4 km (3.9 mi) south of Mauna Loa Summit at a depth of 2.6 km.
