Kilauea volcano update: Lower East Rift Zone eruption continues with little change

This photo take during a 17 June, 2018, morning overflight shows a fissure 8 lava fountain pulsing to heights of 50 m (165 ft) within the cinder spatter cone. (HVO/USGS)

During the morning of June 16, 2018, the fissure 8 lava fountain was pulsing below the rim of the cinder cone that is now 51 m (170 ft) tall at its highest point. The steam in the foreground is the result of heavy morning rain falling on warm (not hot) tephra (lava fragments). (HVO/USGS)

View to the southwest of the lava ocean entry at Kapoho on the morning of 16 June 2018.  Lava from fissure 8 travels about 13 km (8 mi) down a well established channel (visible in the center of the image) to this ocean entry at Kapoho where it is building a seaward delta that is approximately 320 acres in size. The white plume (left) is the vigorous ocean entry at Vacationland where interaction of lava and ocean water creates a dense plume of ‘laze’. (HVO/USGS)

Throughout the weekend, Kilauea’s lower East Rift Zone eruption persisted to vigorously effusive large amounts of lava from fissure 8 which travelled along the well established 13 km (8 mile) channel to the broad ocean entry at Kapoho.

Fissure 8 continues to produce lava fountains with a pulsating height varying from 30 to 60 m (100 – 200 ft). This ongoing spattering of lava has built up an impressive cinder cone that partially encircles the fissure 8 vent and is now 51 m (170 ft) at its highest point. Lower fountains are thereby hidden from view within this cinder cone, but taller fountains are still adding fragments of lava (spatter) that continue to build the cone higher.

From the fissure 8 vent, lava flows freely over small cascades (rapids) into a well-established perched channel that travels for about 13 km (8 mi) to the ocean entry at Kapoho. Near the vent, lava is traveling about 24 km per hour (15 mi per hour) but it slows down to about 2 km per hour (1.5 mi per hour) near the ocean entry at Kapoho. Occasionally, minor amounts of lava briefly spill over the channel levees but overall the flow field seems stable with little change to its size and shape for the past few days.
There has only been a small amount of expansion of lava onto new areas at the southern boundary of the flow near the coast and south of Vacationland. As of 15 June, the total lava flow area of this eruption is 23,9 square km (9,2 square miles) and the new lava delta constructed in the ocean covers 1,3 square km (320 acres).

Hawaiian based photographer Bruce Omori (Extreme Exposure Fine Art Gallery) regularly undertakes early morning helicopter flights over the lower East Rift Zone eruption site after which he shares his best images on Facebook. You can find some impressive shots of the fissure 8 fountain in his Thursday 14 June 2018 album below:


Apart from the vigorous lava fountaining at fissure 8, there is still lava oozing from fissures 16 and 18 which create small lava flows, some mild spattering intermittenly observed from fissures 6 and 15 and increased steaming from fissure 9.

Magma continues to be supplied to the Lower East Rift Zone but seismicity remains relatively low in the area with numerous small magnitude earthquakes and low amplitude background tremor. Higher amplitude tremor is occasionally being recorded on seismic stations close to the ocean entry. (HVO/USGS)

Over the past 2 days, Kilauea's eruptive activity in the lower East Rift Zone persisted with little change. Fissure 8 continues to vigorously effuse lava fountains of varying heights, sometimes 10 meter (35 feet) above the growing cone of cinder and spatter which is now about 45 m (140 ft) at its highest point. ...
