The episode 61g flow continues to enter the ocean at the Kamokuna ocean entry (center) and was producing a robust plume. The western Kamokuna delta, which was abandoned in late September 2016, is visible to the left of the entry. A few weak surface breakouts were still active on the coastal plain, but most surface activity is within approximately 2.2 miles of the vent. The episode 61g tube is marked by fume traces that can be seen along the flow field, and Puʻu ʻŌʻō is visible in the center of the skyline. USGS photo, March 30, 2017.

Kīlauea continues to erupt at its summit and East Rift Zone.

This past week, the summit lava lake level varied between about 39 and 135 feet below the vent rim.

The 61g flow was still active, with lava entering the ocean and building a small delta near Kamokuna and small surface breakouts downslope of Puʻu ʻŌʻō on the pali and the coastal plain.

The 61g flows do not pose an immediate threat to nearby communities.

Mauna Loa is not erupting.
