Volcano Watch: Kilauea activity update for August 29, 2014

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

The summit lava lake within HalemaÊ»umaÊ»u Crater produced nighttime glow that was visible via HVO’s webcam over the past week. The lava lake level was roughly 50‒55 m (165‒180 ft) below the rim of the Overlook crater on Friday, August 29.

On the East Rift Zone of Kīlauea Volcano, the June 27th flow from Puʻu ʻŌʻō remained active. The farthest point on the steaming ground crack was 11.9 km (7.4 mi) from the vent and 2.6 km (1.6 mi) from the east boundary of the Wao Kele o Puna Forest Reserve on August 29. Within the Puʻu ʻŌʻō crater, glow was visible above several outgassing openings in the crater floor.

There was one felt earthquake during the past week across the Hawaiian Islands. On Friday August 22, 2014, at 2:37 a.m., HST, a magnitude-4.2 earthquake occurred 55 km (34 mi) southwest of Maunaloa, Moloka`i, at a depth of 6 km (4 mi).
