This report on the status of Kilauea volcanic activity was prepared by the USGS Hawaiian Volcano Observatory (HVO). All times are Hawai`i Standard Time.

KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: The lava lake at Kīlauea's summit remains active. Summit tiltmeters recorded slow inflationary tilt for most of the past day. The East Rift Zone lava flow northeast of Puʻu ʻŌʻō remains active within 8 km (5 mi) of the vent. The flow does not currently pose a threat to communities. Normal levels of seismic activity continue across the volcano.

Summit Observations: The lava lake dropped several meters during midday yesterday and started to rise slowly through the afternoon and overnight; this morning, the lake level was still more than 50 m (164 ft) below the floor of Halemaʻumaʻu. This is a slight drop compared to yesterday. Episodic bursts of seismic tremor associated with spattering on the surface of the lava lake continue. Tiltmeters at Kīlauea's summit continued to record slow inflationary tilt over the past 24 hrs. Continuing winds from the west-southwest are sending the summit and Puʻu ʻŌʻō gas plumes northeast from their respective sources. Summit sulfur dioxide emission rates ranged from 1,700 to 2,700 metric tons per day for the week ending September 1.

Puʻu ʻŌʻō Observations: Normal activity continues from vents within the crater. No further overflows within Puʻu ʻŌʻō occurred in the past 24 hours. 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 overnight showed continued scattered activity on the flow field northeast of Puʻu ʻŌʻō. Lava breakouts are active only within about 8 km (5 mi) of Puʻu ʻŌʻō and are not threatening any structures. Some breakouts are marked by smoke plumes where lava is creeping into the forest.

Activity Summary: The lava lake at Kīlauea's summit is still active. Summit tiltmeters recorded a brief deflationary tilt signal overnight. The East Rift Zone lava flow northeast of Puʻu ʻŌʻō is also active, and all breakouts remain within 8 km (5 mi) of the vent. A large breakout occurred from the lava tube on the north side of Puʻu ʻŌʻō overnight, and lava erupted in the bottom of Puʻu ʻŌʻō crater. None of the lava flows currently pose a threat to communities but are being monitored closely. Low levels of seismic activity continue across the volcano.

Summit Observations: Kīlauea's summit inflated through the day yesterday and then switched to deflation overnight. Deflation stopped early this morning, and tilt has been flat since. Seismic tremor continues with episodic bursts associated with spattering on the surface of the summit lava lake, which remains active. This morning, the depth to the surface of the lava lake is about 58 m (190 ft) below the floor of Halemaʻumaʻu. Seismicity within the volcano remains at a low level. An earthquake with a preliminary magnitude of 3.8 occurred at 4:39 AM this morning beneath Kīlauea's south flank. Summit sulfur dioxide emission rates ranged from 2,000 to 2,200 metric tons/day for the week ending August 18.

Puʻu ʻŌʻō Observations: There was no change at Puʻu ʻŌʻō through the day yesterday, but early this morning lava began to erupt from a vent on the northeast side of the crater floor. The flow was still slowly spreading within the crater this morning. Seismic activity remains low. The sulfur dioxide emission rate from all East Rift Zone vents was about 390 tonnes/day when measurements were last possible on August 13, 2015.

June 27th Lava Flow Observations:Webcam views overnight show continued activity on the flow field northeast of Puʻu ʻŌʻō. These flows are active within 8 km (5 mi) of Puʻu ʻŌʻō, and some are marked by smoke plumes where lava is creeping into the forest. At 1 AM, a large breakout occurred on the northeast flank of Puʻu ʻŌʻō from the lava tube supplying the distant flows. This breakout was still feeding a channelized flow to the north this morning. It is too soon to tell how important this breakout is or if it will affect the vigor of the distant flows to the northeast.

Puʻu ʻŌʻō Observations: Webcam views of Puʻu ʻŌʻō during the past day showed no changes in the persistent incandescent crater vents. Seismic activity remains low. The sulfur dioxide emission rate from all East Rift Zone vents was about 390 tonnes/day when measurements were last possible on August 13, 2015.

June 27th Lava Flow Observations:Webcam views overnight show continued activity on the flow field when not obscured by rain and fog. The June 27th lava flow is active, with surface flows scattered in 3 areas northeast and east of Puʻu ʻŌʻō. All active flows are within 8 km (5 mi) of Puʻu ʻŌʻō. Location of the most distant flows are marked by smoke plumes that are produced when lava creeps into the forest and burns the vegetation.
