Kīlauea continues to erupt at its summit and East Rift Zone. This past week, the summit lava lake level varied between about 20 and 38 m (66–125 ft) below the vent rim. The 61g flow was still active, with lava entering the ocean near Kamokuna and surface breakouts roughly 5 km (3 mi) from the vent on Pu‘u ‘Ō‘Šand on the coastal plain about 1 km (0.6 mi) inland of the ocean entry, as of Feb. 16. The 61g flows do not pose an immediate threat to nearby communities.
Mauna Loa is not erupting. Rates of deformation and seismicity have not changed significantly in the past week and continue to be above long-term background levels. Only a few small-magnitude earthquakes occurred beneath the volcano, primarily in the upper Southwest Rift and Moku’Äweoweo caldera at depths less than 5 km (3 miles). A few earthquakes also occurred on the west flank of the volcano at depths mostly above 5 km (3 miles). Global Positioning System (GPS) measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone. No significant change in summit fumarole temperature was noted over the past week.
One earthquake was reported felt on the Island of Hawaiʻi this past week. On February 13, 2017, at 10:02 p.m., HST, a magnitude-2.5 earthquake occurred 10.0 km (6.2 mi) southwest of Honoka‘a at a depth of 13 km (8 mi).
