(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

Kīlauea’s summit lava lake level, which fluctuates in response to summit inflation and deflation, varied this past week between about 60 and 67 m (197–220 ft) below the vent rim within Halema‘uma‘u Crater.

Kīlauea’s East Rift Zone lava continues to feed widespread breakouts northeast and east of Puʻu ʻŌʻō. All active lava remains within about 8 km (5 mi) of Puʻu ʻŌʻō. The most distant breakouts are evident by the smoke plumes produced by burning vegetation along the edge of the flow field.

No earthquakes were reported as felt on the Island of Hawai‘i this 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. August 13-20, 2015. Images courtesy of USGS/HVO
