Volcano Watch: Kilauea activity update for April 13, 2017


This video clip shows the Kamokuna ocean entry, with the laze plume blocking the view of the delta. The billowing white cloud rising from the ocean entry is a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

Kīlauea continues to erupt at its summit and East Rift Zone. This past week, the summit lava lake level varied between about 22 and 29 m (71-95 ft) 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, a flurry of more than 150 earthquakes were located beneath the upper west flank of the volcano with a peak of just under 60 quakes on April 08. 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 gas output was noted this past week; the fumarole temperature continued to decrease.

Two earthquakes were reported felt on the Island of Hawai’i in the past week. On Monday, April 10 at 1:31 a.m. HST a magnitude 3.1 earthquake occurred 14.6 km (9.1 mi) northwest of Na`alehu at a depth of 0.9 km (0.6 mi). On Wednesday, April 12 at 8:29 a.m. HST a magnitude 3.5 earthquake occurred 3.7 km (2.3 mi) southwest of Kīlauea Summit at a depth of 2.6 km (1.6 mi).
