High aerial view of Puʻu ʻŌʻō, looking south-southwest. The current crater at Puʻu ʻŌʻō is about 280 m (~920 ft) long and 230 m (~755 ft) wide, with a depth of about 25 m (~82 ft). To the west of the crater is another pit 49 m (~161 ft) across that contains a small lava pond. Photo taken Tuesday, August 4, 2015 courtesy of USGS/HVO

The pit west of the Puʻu ʻŌʻō crater, shown here, is overhung on most sides and may continue to widen with time. The lava pond inside is relatively placid, appearing as a black surface, usually with a few tiny spattering areas along the edge. Photo taken Tuesday, August 4, 2015 courtesy of USGS/HVO

Lava flows are scattered across a broad area extending from about 3 to 8 km (2–5 mi) northeast of Puʻu ʻŌʻō. The active flows start just above the horizontal mid-line of the photo, but cannot be picked out easily within the broader inactive flow field due to their distance away in this photo. The most distant active lava is burning forest, and the bluish smoke from this can be seen in a few areas in the distance, partly shrouded by clouds.

An HVO scientist collects a molten lava sample using a rock hammer. Molten lava on the flow field for the last several months has had a temperature usually around 1,140 ºC, or just under 2,100 ºF, when collected and can blister exposed skin when this close.

KÄ«lauea’s summit lava lake level fluctuated this past week between about 48 and 51 m (157 – 167 ft) below the vent rim.

KÄ«lauea’s East Rift Zone “June 27th lava flow” continues to feed widespread breakouts northeast of PuÊ»u ʻŌʻō. All active lava remains within about 8 km (5 mi) of PuÊ»u ʻŌʻō. The most distant breakouts are evident by the smoke plumes produced by burning vegetation along the edge of the flow field.

One earthquake was reported felt on the Island of Hawai’i in the past week. On Monday, August 3, 2015 at 12:38AM, HST a magnitude 2.9 earthquake occurred 19.6 km (12.2 mi) northwest of Kawaihae at a depth of 17.5 km (10.9 mi).

Time-lapse movie from images gathered from a temporary thermal camera looking into Pu’u ‘O’o Crater. The temperature scale is in degrees Celsius up to a maximum of 500 Celsius (932 Fahrenheit) for this camera model, and scales based on the maximum and minimum temperatures within the frame. Thick fume, image pixel size and other factors often result in image temperatures being lower than actual surface temperatures. July 30-August 6, 2015. Images courtesy of USGS/HVO
