This past week, Kīlauea Volcano’s summit lava lake level fluctuated with summit inflation and deflation, ranging about 30–40 m (99–131 ft) below the vent rim. On the East Rift Zone, the 61g lava flow remained active downslope of Pu‘u ‘Ō‘ō, with scattered breakouts on the pali and coastal plain. The 61g flows do not pose an immediate threat to nearby communities.
Mauna Loa is not erupting. Small-magnitude earthquakes occurred beneath the summit caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi), with a few deeper earthquakes scattered beneath the volcano’s southeast and west flanks at depths of 5-13 km (3-8 mi). GPS measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone. No significant changes in volcanic gas emissions were measured.
One earthquake was reported felt on the Island of Hawaiʻi this past week. On November 25, at 12:48 p.m. HST, a magnitude-2.8 earthquake occurred 12 km (7 mi) south of Kapa‘au at a depth of 27 km (17 mi).

Time-lapse movie from a camera positioned on the southeast flank of Puʻu ʻŌʻō, looking toward the active flow advancing to the southeast. The breakout point is at the left edge of the image, and the mid-field skyline at the right is roughly coincident with the top of the pali. November 23-30, 2017. Images courtesy of USGS/HVO
