Kilauea , Hawai : Two new flows from Pu’u ‘O’o that began on May 24 are still active,

Activity Summary:
Kilauea Volcano continues to erupt at its summit and East Rift Zone. Minor inflationary tilt at the summit was accompanied by a modest rise in the lava level height to 31 m (102 ft) below the rim of the Overlook crater. Two new flows from Pu’u ‘O’o that began on May 24 are still active, but have advanced minimally in the past week. Scattered activity is still occurring on the June 27th lava flow field. All flows are within about 5.4 km (3.4 mi) of Pu’u ‘O’o and none currently pose a threat to nearby communities.

Summit Observations:
Minor inflationary tilt continued following yesterday’s DI event and the level of the lava lake within the Halema’uma’u Overlook crater rose slightly to 31 m (102 ft) below the Overlook crater rim. Rates of seismicity are at background levels, with episodes of tremor associated with changes in the vigor of spattering within the Overlook vent. Sulfur dioxide emissions from the summit vent ranged from 4,100 to 8,000 metric tons/day when measurements were possible during good trade wind conditions over the past two weeks. Data from GPS networks and InSAR (satellite radar) show continued long-term inflation of the summit and upper Southwest Rift Zone magma reservoirs.

Pu’u ‘O’o Observations:
Lava flow breakouts from the north and east flanks of Pu’u ‘O’o, which began on May 24, are still active. Neither has advanced significantly in the past week and are primarily resurfacing areas they had already covered. Both are within 1.3 km (0.8 mi) of their respective vents on the flanks of Pu’u ‘O’o. No significant tilt was recorded by nearby tiltmeters over the past day and seismicity is at background levels throughout the East Rift Zone. For recent photographs and maps of these two new active flows, see web links below. The sulfur dioxide emission rate from all East Rift Zone vents was about 410 metric tons/day when last measured on June 1.

9°25’16” N 155°17’13” W,
Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

 

June 27th Lava Flow Observations:
Scattered breakouts continue to occur on the June 27th flow field. This is in addition to the two new breakouts on Pu’u ‘O’o’s flanks. The most recent aerial observations indicate that the active breakouts are within about 5.4 km (3.4 mi) northeast of Pu’u ‘O’o. The flows are not currently threatening any nearby communities.
