Recent Kilauea Status Reports, Updates, and Information Releases

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, July 7, 2015 9:55 AM HST (Tuesday, July 7, 2015 19:55 UTC)


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: Kīlauea Volcano continues to erupt at its summit and East Rift Zone. At the summit, the lava lake continues to circulate and occasionally spatter, producing a gas plume during the day and glow at night. At the East Rift Zone, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.

Summit Observations: Summit tiltmeters recorded the start of slow inflationary tilt yesterday afternoon. In concert with the tilt, the level of the lava lake rose a bit and is 39 m (128 ft) below the rim of the Overlook crater this morning. Seismicity rates beneath Kīlauea's summit continued within background values, with bursts of seismic tremor associated with periods of vigorous spattering of the lava lake. Sulfur dioxide emission rates ranged between 2,100-2,700 tonnes/day for the week ending June 30.

Puʻu ʻŌʻō Observations: There have not been any significant changes at Puʻu ʻŌʻō. Seismicity rates are at background levels. Webcams show multiple incandescent outgassing vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on June 19, 2015.

June 27th Lava Flow Observations: Webcam images indicate that active lava breakouts continue within an area extending about 8 km (5 mi) northeast Puʻu ʻŌʻō.

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: There have been no significant changes in the summit and East Rift Zone eruptions of Kīlauea Volcano. At the summit, the lava lake was briefly disrupted by a wall collapse yesterday afternoon, then resumed its usual patterns of circulation and occasional spattering, producing a gas plume during the day and glow at night. At the East Rift Zone, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.

Summit Observations: Summit tiltmeters have not recorded any significant tilt trends since Sunday, June 26th. Part of the rim and wall of the Overlook crater collapsed into the lava lake yesterday afternoon starting about 2:30. As seen previously with such events, an ashy plume, rapid oscillation of lava lake level, and intense spattering in the lake at the impact site were produced. There was no appreciable net change in the lava lake level over the past day and it remains at about 47 m (155 ft) below the rim of the Overlook crater. Seismicity rates beneath Kīlauea's summit continued within background values, with bursts of seismic tremor associated with periods of vigorous spattering of the lava lake. Sulfur dioxide emission rates ranged between 2,100-2,700 tonnes/day for the week ending June 30.

Puʻu ʻŌʻō Observations: There have not been any significant changes at Puʻu ʻŌʻō. Seismicity rates are at background levels. Webcams show multiple incandescent outgassing vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on June 19, 2015.

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: There have been no significant changes in the summit and East Rift Zone eruptions of Kīlauea Volcano. At the summit, the lava lake continued to circulate and occasionally spatter producing a gas plume during the day and glow at night. At the East Rift Zone eruption site, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.

Summit Observations: Summit tiltmeters have not recorded any significant tilt trends since Sunday the 26th. The lava lake level dropped about 4.5 m (15 ft) during the past day and is about 47 m (155 ft) below the rim of the Overlook crater this morning. Seismicity rates beneath Kīlauea's summit continued within background values, with bursts of seismic tremor associated with periods of vigorous spattering of the lava lake. Sulfur dioxide emission rates ranged between 2,200-3,700 tonnes/day for the week ending June 23.

Puʻu ʻŌʻō Observations: There have not been any significant changes at Puʻu ʻŌʻō. Seismicity rates are at background levels. During an overflight yesterday, geologists observed two incandescent vents in the southern portion of Puʻu ʻŌʻō crater, and a robust outgassing plume coming from the wall of a pit in the northeast part of the crater. A mostly crusted-over lava pond remains deep within a large circular pit in the west portion of the crater, which was bubbling lazily along its margin yesterday. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on June 19, 2015.

June 27th Lava Flow Observations: Yesterday's overflight confirmed our observations from webcam images that active lava from breakouts continue within an area extending about 8 km (5 mi) northeast Puʻu ʻŌʻō. There had been no downslope advancement between the previous overflight on June 19 and yesterday morning, and only moderate expansion of flow margins.

HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, June 30, 2015 6:45 AM HST (Tuesday, June 30, 2015 16:45 UTC)


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: There have been no significant changes in the summit and East Rift Zone eruptions of Kīlauea Volcano. At the summit, the lava lake was briefly disrupted by a wall collapse but continued to circulate and occasionally spatter producing a gas plume during the day and a glow at night. At the East Rift Zone eruption site, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.

Summit Observations: Tilt remained flat and stable since Friday morning with a small offset at 2:44 am this morning. The offset coincides with the collapse of a sliver of the north wall of the Halema‘uma‘u Overlook Crater that briefly disrupted the surface of its lava lake. This morning, the lava lake level is about 42 m (138 ft) below the Halema‘uma‘u Crater floor (the new rim). Seismicity rates beneath Kīlauea's summit continued within background values, with bursts of seismic tremor associated with periods of vigorous spattering within the Overlook crate; the wall collapse early this morning created a strong seismic signal that lasted for several minutes. Sulfur dioxide emission rates ranged between 2,200-3,700 tonnes/day for the week ending June 23.

Puʻu ʻŌʻō Observations: No significant changes noted. Seismicity rates are at background levels. The sulfur dioxide emission rate from all East Rift Zone vents was about 700 tonnes/day when last measured on June 19, 2015.

June 27th Lava Flow Observations: Webcam images (PNcam and R3cam) continue to show active lava from breakouts (smoke by day and glow by night) within an area extending about 8 km (5 mi) northeast Puʻu ʻŌʻō.
