Kīlauea continues to erupt at its summit and East Rift Zone. During the past week, the summit lava lake level varied between about 24 m and 35 m (79–115 ft) below the vent rim within Halema‘uma‘u Crater. On the East Rift Zone, the eastern Pu‘u ‘Ō‘ō breakout remained active, producing a lava flow (informally called the “61g flow”) that continued to advance to the southeast. As of mid-day on July 7, 2016, the flow was about 1.2 km (0.7 mi) from the ocean. The lava flow does not pose an immediate threat to nearby communities.

Mauna Loa is not erupting. Seismicity rates remain above background levels. Deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone continues, with inflation recently occurring mainly in the southwestern part of Mauna Loa’s magma storage complex.

No earthquakes were reported felt on the Island of Hawaiʻi this past week.
