Volcano Activity Update: April 6, 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.
During the past week, small-magnitude earthquakes continued to occur beneath the volcano.
No earthquakes were reported felt in the Hawaiian Islands during the past week.
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 the summit fumarole temperature or gas output was noted this past week.
