The lava lake at Kilauea’s summit remains active. Summit tiltmeters recorded slow deflationary tilt overnight. The East Rift Zone lava flow northeast of Pu’u’O’o remains active within 8 km (5 mi) of the vent and does not currently pose a threat to communities. Normal levels of seismic activity continue across the volcano.
The lava lake dropped several meters with deflationary tilt overnight to a level about 60 m (197 ft) below the floor of Halema’uma’u – a drop of about 10 m (33 ft) from yesterday morning’s level. Episodic bursts of seismic tremor associated with spattering on the surface of the lava lake continued. Tiltmeters at Kilauea’s summit recorded the start of slow deflationary tilt at about 6 pm yesterday. Weak winds allow the summit gas plume to rise vertically before being blown slowly to the west this morning. Summit sulfur dioxide emission rates ranged from 1,700 to 2,700 metric tons per day for the week ending September 1.
Normal activity (continuous gas release and glow at night) continued from vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 390 metric tons per day when measurements were last possible on August 13, 2015.
June 27th Lava Flow Observations:
Clear webcam views yesterday and overnight showed continued scattered activity on the flow field northeast of Pu’u ‘O’o. Lava breakouts are active only within about 8 km (5 mi) of Pu’u ‘O’o and are not threatening any structures. Some breakouts are marked by smoke plumes where lava is creeping into the forest.
