Lower East Rift Zone Eruption

The intermittent eruption of lava in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano continues. Fissure 7 stopped erupting in mid-afternoon. A new fissure erupted this evening near fissures 2 and 7, and lava fountains reached as high as about 70 m (230 ft). Early this morning, new ground cracks were reported on Highway 130, but no heat or escaping steam was subsequently observed.

Seismicity and deformation are consistent with continued accumulation of magma within the rift zone.

Residents should remain informed and heed Hawaii County Civil Defense closures, warnings, and messages (http://www.hawaiicounty.gov/active-alerts).

HVO geologists will be in the area overnight to track and report to Hawaii County Civil Defense on the activity, and other scientists are closely tracking the volcano’s overall activity using various monitoring data streams.

Kīlauea Volcano Summit

Tiltmeters at the summit of Kīlauea Volcano continue to record the deflationary trend of the past several days. Satellite InSAR data show that between April 23 and May 5, 2018, the summit caldera floor subsided about 10 cm (4 in). Corresponding to this deflationary trend, the summit lava lake level in Overlook crater has dropped about 128 m (518 ft) below the crater rim since April 30. Rockfalls from the crater walls into the retreating lake produced ashy plumes above Halemaumau crater today, resulting in light ashfall in the summit area. Rockfalls and ashy plumes are expected to continue as the lake level drops.

Earthquake activity in the summit increased in the past 2 days, coincident with the magnitude-6.9 earthquake on May 4 beneath the south flank of Kīlauea. In the past two days, about 152 magnitude-2 and magnitude-3 earthquakes occurred at depths less than 5 km (3 miles) beneath the summit area. Twenty two magnitude 3 earthquakes were recorded. These earthquakes are related to the ongoing subsidence of the summit area and beneath the south flank of the volcano.

Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

Eruption of lava in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano continues. Several additional eruptive fissures or vents – each several hundred yards long – have opened over the past day. No significant lava flows have yet formed. Spatter and lava are accumulating primarily within a few tens of yards of the vent.

The sixth and most recent fissure is on the eastern edge of the subdivision. Not all fissure vents remain active and no far-traveled lava flows have formed.

For maps showing the locations of these features, please see https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html

HVO geologists will be in the area overnight to track additional activity that may occur, and other scientists are closely tracking the volcano’s overall activity using various monitoring data streams.

Seismicity and deformation are consistent with continued accumulation of magma within the rift zone. Additional outbreaks of lava are expected.

Residents should remain informed and heed Hawaii County Civil Defense messages (http://www.hawaiicounty.gov/active-alerts).

ABOVE: A new lava fissure (Fissure 2) commenced around 1:00 am HST on Kīlauea Volcano’s lower East Rift Zone on Makamae and Leilani Streets in the Leilani Estates subdivision. Spatter was being thrown roughly 30 m (about 100 ft) high at the time of this photo. Copious amounts of sulfur dioxide gas, which should be avoided, is emitted from active fissures. The eruption is dynamic and changes could occur with little warning. TOP: Steaming cracks at 5:57 a.m. HST in Leilani Estates subdivision, moments before Fissure 3 opened up on Kaupili Street.

Current Volcano Alert Level: WARNING
Current Aviation Color Code: ORANGE

The eruption in the Leilani Estates subdivision in the lower East Rift Zone of Kīlauea Volcano that began in late afternoon ended by about 6:30 p.m. HST. Lava spatter and gas bursts erupted from the fissure for about two hours, and lava spread a short distance from the fissure, less than about 10 m (33 ft).

At this time, the fissure is not erupting lava and no other fissures have erupted.

HVO geologists are working near the fissure overnight to track additional activity that may occur, and other scientists are closely tracking the volcano’s overall activity.

Recent Observations

• Sulfur gas is quite noticeable around the fissure…
• Lava flows did not advance more than about 10 m (33 ft) from the fissure. The flows are no longer active.
• No other fissures have erupted from along the rift zone currently.
• Tiltmeters at Kīlauea’s summit continue to record deflationary tilt and the lava lake level has dropped about 37 m (121 ft) in the past 24 hours.
• Seismic activity has not changed significantly during the day or since the brief fissure eruption.

TOP: A view of Pu‘u ‘Ō‘ō from the east, shortly after a small collapse. The coating of red ash on the south side of the cone (left side of photo) is evident. ABOVE: At 10:31 a.m. HST, while HVO geologists were working on Pu‘u ‘Ō‘ō, a magnitude-5.0 earthquake shook the ground around the cone. Moments later, a collapse occurred in the crater of Pu‘u ‘Ō‘ō, creating a robust, reddish-brown ash plume. [Source: volcanoes.usgs.gov]

At 10:30 HST (May 3), ground shaking from a preliminary magnitude-5.0 earthquake south of Pu‘u ‘Ō‘ō caused rockfalls and possibly additional collapse into the Pu‘u ‘Ō‘ō crater on Kīlauea Volcano’s East Rift Zone. A short-lived plume of ash produced by this event lofted skyward and dissipated as it drifted southwest from Pu‘u ‘Ō‘ō. Downwind areas may have experienced a dusting of ash from this plume. At this time, the 10:30 earthquake has caused no other changes at Kīlauea Volcano. HVO will continue to closely watch monitoring data for any changes. This image was captured from an HVO overflight carrying HVO scientists to the East Rift Zone for field work today. USGS photo by Kevan Kamibayashi.

Kīlauea Latest Images: November 2, 2014

A breakout occurs from an inflated lobe of the June 27th lava flow on Sunday morning, November 2, 2014. Scattered breakouts like this, which took place about 200 meters (218 yards) upslope of the stalled leading edge, have been common over the past few days and are filling in low points behind the flow front. [Source: HVO]

Summit Observations: At Kīlauea volcano’s summit, tilt and lava lake level inferred from the webcams continue their gradual recoveries following last week’s DI event. Volcanic tremor persists at low amplitudes which show episodic fluctuation. There are no significant local seismic events evident on the seismograms from the NPT seismic station that is closest to Halemaʻumaʻu Crater. Sulfur-dioxide emission rate measurements for the summit ranged from 4,250 up to 7,000 tonnes/day (see caveat below) through the week-long period ending October 28, 2014. A small amount of particulate material was carried aloft by the plume. [HVO]

Activity Summary: Kīlauea volcano continued to erupt at its summit and within its East Rift Zone, and gas emissions remained elevated. As of Monday morning, the leading edge of the June 27th lava flow had not advanced beyond where it stalled late last week, in a residential area approximately 155 meters (170 yards) above Pāhoa Village Road. Activity behind the lava flow’s leading edge, within the flow’s interior and along its side margins, continued with localized breakouts of molten lava. Gradual inflation was recorded by the tiltmeters at Kīlauea’s summit. The level of the summit lava lake at Halemaʻumaʻu Crater, as reflected in web cam images, has also risen since Sunday. [HVO]
