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 29.5 m (97 ft) below the crater rim on Friday, April 29, 2016. Tiltmeters at Kīlauea's summit have recorded deflationary tilt. 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. Small pāhoehoe ooze outs continue on the crater floor from the eastern vent within the crater. Seismic activity remains low at Puʻu ʻŌʻō. A tiltmeter on the cone recorded no significant change since yesterday when we noted the tilt was 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.

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.

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: Kīlauea continues to erupt at both the summit, where there is a circulating lava lake, and from its East Rift Zone, where surface lava flows are active northeast of the Puʻu ʻŌʻō vent. The East Rift Zone lava flow currently poses no threat to nearby communities. Summit tiltmeters recorded deflationary during the past 24 hours; earthquake rates and seismic tremor have not changed significantly in the past day.

Summit Observations: Summit tiltmeters continued to record the deflationary tilt that began early Monday although the rate of tilt appears to be slowing as of this morning. The summit lava lake level when measured Monday morning was 32 m (105 ft) below the current Halema`uma`u crater floor. Based on web camera imagery, the lake level appeared to dropped a few meters since that time. Seismic activity has not changed significantly during the past day. Fluctuations in summit tremor amplitudes are related to spattering along the edges of the lava lake. The average sulfur dioxide emission rates during the past week ranged between 4,200 and 5,200 metric tons/day; the most recent average emission rate on April 25 was about 4,900 metric tons/day.


Puʻu ʻŌʻō Observations: There were no observable changes at Puʻu ʻŌʻō during the past day. Outgassing continues from the spatter cones on the crater floor. A tiltmeter on the north flank of Puʻu ʻŌʻō began recording deflationary tilt beginning at around 04:00 this morning. 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: During periods of clear weather, webcam images continue to show 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.

Activity Summary: Kīlauea continues to erupt at both the summit, where there is a circulating lava lake, and from its East Rift Zone, where surface lava flows are active northeast of the Puʻu ʻŌʻō vent. The East Rift Zone lava flow currently poses no threat to nearby communities. Summit tiltmeters began recording deflationary tilt after midnight; earthquake rates and seismic tremor have not changed significantly in the past day.

Summit Observations: Summit tiltmeters began to record deflationary tilt this morning around 2:30 am. The summit lava lake level when measured Friday morning was 39 m (128 ft) below the current Halema`uma`u crater floor. Based on web camera imagery, the lake level appeared to have risen a few meters yesterday before the tilt turnaround. The level has decreased since that time and is similar to that of yesterday morning. Seismic activity has not changed significantly during the past day. Fluctuations in summit tremor amplitudes are related to spattering along the edges of the lava lake. The average sulfur dioxide emission rates during the past week ranged between 1,200 and 4,300 metric tons/day.

Puʻu ʻŌʻō Observations: There were no observable changes at Puʻu ʻŌʻō during the past day. Outgassing continues from the spatter cones on the crater floor. A tiltmeter on the north flank of Puʻu ʻŌʻō has recorded steady inflationary tilt for the past several days. 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: During periods of clear weather, webcam images continue to show 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.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, April 23, 2016 8:01 AM HST (Saturday, April 23, 2016 18:01 UTC)


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: Kīlauea continues to erupt at both the summit, where there is a circulating lava lake, and from its East Rift Zone, where surface lava flows are active northeast of the Puʻu ʻŌʻō vent. The East Rift Zone lava flow currently poses no threat to nearby communities. Summit tiltmeters recorded inflationary tilt during the past 24 hours; earthquake rates and seismic tremor have not changed significantly in the past day.

Summit Observations: Summit tiltmeters continue to record inflationary tilt this morning. The summit lava lake level when measured Friday morning was 39 m (128 ft) below the current Halema`uma`u crater floor. Based on web camera imagery, the lake level has risen in the last 24 hours. Seismic activity across the volcano has not changed significantly during the past day. Fluctuations in summit tremor amplitudes are related to spattering along the edges of the lava lake. The average sulfur dioxide emission rates during the past week ranged between 1,600 and 7,200 metric tons/day; the average emission rate on April 21 was 7,200 metric tons/day.

Puʻu ʻŌʻō Observations: There were no observable changes at Puʻu ʻŌʻō during the past day. Outgassing continues from the spatter cones on the crater floor. A tiltmeter on the north flank of Puʻu ʻŌʻō recorded minor inflationary tilt over the past 24 hours. 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 continue to show 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.
