HAWAIIAN VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Wednesday, July 1, 2015 9:25 AM HST (Wednesday, July 1, 2015 19:25 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 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

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.

Activity Summary: There have been no significant changes in the summit and East Rift Zone eruptions of Kīlauea Volcano. At the summit, a lava lake continues 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.

At the East Rift Zone eruption site, surface flows are still active within about 8 km (5 mi) northeast of Puʻu ʻŌʻō.

Summit Observations: The flip-flop continued: deflationary tilt turned into inflationary tilt about 3 pm yesterday. The lava lake level within the Overlook crater rose slightly since yesterday afternoon but remained fairly stable after midnight at about 45 m (148 ft) below the new rim;note that the lake surface position was incorrectly reported yesterday at 40 m below the new rim and should have been 49 m (161 ft). Seismicity rates beneath Kīlauea's summit continued at background levels, with bursts of seismic tremor associated with periods of vigorous spattering within the Overlook crater resuming this morning.

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 notable changes in the summit and East Rift Zone eruptions of Kīlauea Volcano. At the summit, a lava lake continues to circulate and occasional 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: Inflationary tilt continued to be recorded by summit tiltmeters while the lava lake level within the Overlook crater rose slowly; a dramatic brief reversal in circulation of the lake occurred yesterday afternoon and resulted in a drop of several meters before the lake resumed rising overnight to about 40 m below the new rim this morning. Seismicity rates beneath Kīlauea's summit continued at background levels, with bursts of seismic tremor associated with periods of vigorous spattering within the Overlook crater. Sulfur dioxide emission rates ranged between 3,000-6,000 tonnes/day for the week ending June 16.

Puʻu ʻŌʻō Observations: No significant changes noted. Seismicity rates are at background levels although seismic tremor increased slightly. The sulfur dioxide emission rate from all East Rift Zone vents was about 725 tonnes/day when last measured on June 19, 2015.

June 27th Lava Flow Observations: Webcam images 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.
