This past week, KÄ«lauea Volcano’s summit lava lake level fluctuated with summit inflation and deflation, ranging about 29–37 m (95–121 ft) below the vent rim. On the East Rift Zone, the 61g lava flow remained active downslope of Pu‘u ‘Ō‘Å, with scattered breakouts on the pali and coastal plain, but no ocean entry. The 61g flows do not pose an immediate threat to nearby communities.
Mauna Loa Volcano is not erupting. Rates of deformation and seismicity remain above long-term background levels. Small-magnitude earthquakes occurred beneath the summit caldera and upper Southwest Rift Zone at depths less than 5 km (3 mi). A few deeper earthquakes were scattered beneath the volcano’s flanks at depths less than 13 km (8 mi). GPS and InSAR measurements continue to show slow deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone, but rates in the past few months have decreased compared to rates of the past year. No significant changes in volcanic gas emissions were measured.
No earthquakes were reported felt in Hawaii this past week.

Time-lapse movie from a camera positioned on the southeast flank of PuÊ»u ʻŌʻÅ, 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. February 1-8, 2018. Images courtesy of USGS/HVO
