Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 21.5 m and 26 m (70–85 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, the “61g†flow continued to advance to the southeast, and, at 1:15 a.m., HST, on July 26, 2016, lava reached the ocean for the first time since August 2013. The lava flow does not pose an immediate threat to nearby communities.
Mauna Loa is not erupting. In the past week, earthquakes at Mauna Loa occurred beneath the west flank of the volcano mostly in the 5–11 km (3–7 miles) depth range. In addition, earthquakes are occurring in south caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi). Seismicity rates on Mauna Loa overall were lower this week compared with the previous update. 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.
Two earthquakes were reported felt on the Island of Hawaiʻi this past week. On Friday, July 22, at 9:16 p.m., HST, a magnitude-4.3 earthquake occurred 5.4 km (3.3 mi) northwest of Captain Cook at a depth of 11.5 km (7.1 mi). On Tuesday, July 26, at 2:33 p.m., HST, a magnitude-2.7 earthquake occurred 2.1 km (1.3 mi) southeast of Kīlauea Summit at a depth of 0.9 km (0.6 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 21-28, 2016. Images courtesy of USGS/HVO
