Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 35 m and 46 m (115–151 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, the “61g” flow continued to advance across the coastal plain and enter the ocean at multiple points. The lava flow does not pose an immediate threat to nearby communities.

Mauna Loa is not erupting. In the past week, earthquakes have occurred mostly in the south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi), with the overall seismicity rate about the same as last week, but still elevated relative to the long-term background rate. Global Positioning System (GPS) measurements show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, with inflation occurring mainly in the southwestern part of the magma storage complex.

No earthquakes were reported felt on the Island of Hawaiʻi 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 4-11, 2016. Images courtesy of USGS/HVO
