KÄ«lauea’s summit lava lake level fluctuated in response to summit inflation and deflation during the past week, with measurements ranging between 51 m (167 ft) and 41 m (135 ft) below the vent rim.

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.

There were no earthquakes reported felt on the Island of Hawai‘i during the past week.

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 9-16, 2015. Images courtesy of USGS/HVO
