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

KÄ«lauea’s summit lava lake level, which fluctuates in response to summit inflation and deflation, varied this past week between about 50 and 60 m (164–197 ft) below the vent rim within Halema‘uma‘u Crater.

KÄ«lauea’s East Rift Zone lava continues to feed widespread breakouts northeast and east of PuÊ»u ʻŌʻō. All active lava remains within about 8 km (5 mi) of PuÊ»u ʻŌʻō. Some breakouts are evident by smoke plumes from burning vegetation where lava creeps into the forest.

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. August 27-September 3, 2015. Images courtesy of USGS/HVO

This map shows recent changes to Kīlauea’s active East Rift Zone lava flow field. The area of the flow on August 5 is shown in pink, while widening and advancement of the flow as of August 26 is shown in red. The yellow lines show the active lava tube system. Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray.  The base map is a partly transparent 1:24,000-scale USGS digital topographic map draped over a 10-m digital elevation model (DEM).
