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: Eruptive activity continues at Kīlauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano remain at background levels. Scattered lava flow activity continues on the June 27th lava flow field within about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. These flows currently pose no threat to nearby communities.

Summit Observations: The lava lake within the Halemaʻumaʻu Overlook crater remains active. The lava lake continued to fall until about 9 pm last night when it started to rise; this morning, the lava lake level is about 38 m (125 ft) below the Halema`uma`u Crater floor. Tiltmeters at Kīlauea's summit recorded continued deflationary tilt until about 8 pm last night when it switch to inflationary tilt. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Emissions from the summit vent averaged about 5,000 t/d when measured during the past week.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from skylights in the lava tube on the northeast flank of the cone. The small lava flow that issued from the northeast source within the crater floor early Wednesday morning continued intermittent activity until 6 pm last night. Seismic activity remains low at Puʻu ʻŌʻō. A tiltmeter on the cone recorded minor fluctuations. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on May 02.

June 27th Lava Flow Observations: Webcam images show continued surface flow activity on the June 27th flow field in the form of small breakouts scattered northeast of Puʻu ʻŌʻō where they have been occurring for the past several months. This pattern is consistent with field observations on April 12, when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. The flows are not currently threatening any nearby communities.

Tiltmeters at Kīlauea's summit recorded continued deflationary tilt. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Emissions from the summit vent averaged about 5,000 t/d when measured during the past week.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from skylights in the lava tube on the northeast flank of the cone. The small lava flow that issued from the northeast source within the crater floor early yesterday morning continued intermittent activity through this morning. Seismic activity remains low at Puʻu ʻŌʻō. A tiltmeter on the cone recorded minor fluctuations. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on May 02.

June 27th Lava Flow Observations: Webcam images show continued surface flow activity on the June 27th flow field in the form of small breakouts scattered northeast of Puʻu ʻŌʻō where they have been occurring for the past several months. This pattern is consistent with field observations on April 12, when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō.

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: Eruptive activity continues at Kīlauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano remain at background levels. Scattered lava flow activity continues on the June 27th lava flow field within about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. These flows currently pose no threat to nearby communities.

Summit Observations: The lava lake within the Halemaʻumaʻu Overlook crater remains active. After rising so that the spattering lava could be seen above the rim early this morning, the level dropped and was estimated at about 30 m (100 ft) below the crater rim after sunrise. Tiltmeters at Kīlauea's summit recorded inflationary tilt with gradual switch to deflationary tilt beginning at 9:30 pm yesterday. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate averaged 4,500 metric tons/day last week.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from skylights in the lava tube on the northeast flank of the cone. A small lava flow issued from the northeast source within the crater floor starting at 3:15 am this morning. Seismic activity remains low at Puʻu ʻŌʻō. A tiltmeter on the cone recorded inflationary tilt switching abruptly to deflation after the start of the lava flow within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on May 02.

June 27th Lava Flow Observations: Webcam images show continued surface flow activity on the June 27th flow field. The active flows are comprised of small breakouts scattered northeast of Puʻu ʻŌʻō, where they have been occurring for the past several months. This pattern is consistent with field observations on April 12, when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. The flows are not currently threatening any nearby communities.

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: Eruptive activity continues at Kīlauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano remain at background levels. Scattered lava flow activity continues on the June 27th lava flow field within about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. These flows currently pose no threat to nearby communities.

Summit Observations: The lava lake within the Halemaʻumaʻu Overlook crater remains active and was measured at 31.5 m (103 ft) below the crater rim when it was last measured on Wednesday, April 27, 2016. Tiltmeters at Kīlauea's summit have transitioned from inflationary tilt to flat. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate averaged 4,900 metric tons/day on April 25.

Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from skylights in the lava tube on the northeast flank of the cone. A small flow spilled out onto the crater floor from the eastern vent last night. Seismic activity remains low at Puʻu ʻŌʻō. A tiltmeter on the cone recorded deflationary tilt event, possibly due to the flow that spilt out onto the crater floor. Now the tilt is flat. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on April 20.

June 27th Lava Flow Observations: Webcam images show continued surface flow activity on the June 27th flow field. The active flows are comprised of small breakouts scattered northeast of Puʻu ʻŌʻō, where they have been occurring for the past several months. This pattern is consistent with field observations on April 12, when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Puʻu ʻŌʻō. The flows are not currently threatening any nearby communities.
