Kīlauea continues to erupt at its summit and East Rift Zone. This past week, the summit lava lake level varied between about 15 and 34 m (49–112 ft) below the vent rim. The 61g flow was still active, with lava entering the ocean near Kamokuna and surface breakouts near Pu‘u ‘Ō‘ō. The 61g flows do not pose an immediate threat to nearby communities.

Mauna Loa is not erupting. During the past week, small-magnitude (up to magnitude 3.0) earthquakes continued, primarily beneath the upper Southwest Rift Zone and the Northeast Rift zone at depths less than 5 km (3 miles). A small number of earthquakes also occurred on the west flank of the volcano at depths above 13 km (8 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.

Three earthquakes were reported felt in Hawaii this past week. On February 3, 2017, at 10:07 a.m., HST, a magnitude-2.8 earthquake occurred 4.8 km (3.0 mi) north of Mauna Loa’s summit at a depth of 10 km (6 mi), and at 12:41 a.m., a magnitude-3.4 earthquake occurred 13.8 km (8.6 mi) southeast of Kīlauea’s summit at a depth of 9 km (5 mi). On February 6, at 12:08 a.m., a magnitude-3.0 earthquake occurred 69.1 km (42.9 mi) southwest of Mākena, Maui, at a depth of 44 km (27 mi).
