This video clip shows the lava stream pouring out of the tube into the Pacific Ocean, triggering pulsating explosions that are throwing bits of lava onto the top of the sea cliff. Video taken Wednesday, January 25, 2017 courtesy of USGS/HVO

KÄ«lauea continues to erupt at its summit and East Rift Zone. This past week, the summit lava lake level varied between about 12 and 22 m (39–72 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‘Å. The 61g flows do not pose an immediate threat to nearby communities.
Mauna Loa is not erupting. During the past week, small-magnitude earthquakes continued, primarily beneath the upper Southwest Rift Zone at depths less than 5 km (3 mi). A small number of earthquakes also occurred on the west flank of the volcano at depths above 13 km (8 mi). GPS measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone.
One earthquake was reported felt on the Island of Hawaiʻi in the past week. On January 23, at 9:13 a.m., HST, a magnitude-3.2 earthquake occurred 12.8 km (8.0 mi) southeast of Ho‘okena at a depth of 12.7 km (7.9 mi).
