Kilauea Eruption: Lava flow continues, higher SO2 levels may occur Monday night (July 9)

Hawaiian Volcano Observatory reports that Fissure 8 continues to be very active and is feeding a lava channel to the ocean at Kapoho. The flow is producing a broad ocean entry along the shoreline and continues to expand into Kapoho Beach Lots and north of Four Corners intersection. There is no immediate threat at this […]

Fissure 8 (lower right) and open lava channel leading to the northeast. Geologists noted small lava-level fluctuations in the open channel overnight, which indicates intermittent variations in lava discharge from fissure 8. An increase in lava levels was noted about 1.5 hours after the collapse-explosion event at the volcano's summit at 02:55 a.m. HST. Evidence of a couple of recent, short-lived channel overflows were observed early this morning, but they had not reached the edge of the flow field. The small steam plumes in distance mark locations of fissures that erupted in early May at the beginning of the ongoing eruption. Photo taken Sunday, July 8, 2018 courtesy of U.S. Geological Survey

This animated GIF shows a sequence of radar amplitude images that were acquired by the Agenzia Spaziale Italiana CosmoSkyMed satellite system. The images illustrate changes to the caldera area of Kīlauea Volcano that occurred between May 5 and July 4 at about 6:00 a.m. HST. The satellite transmits a radar signal at the surface and measures the strength of the return, with bright areas indicating a strong return and dark areas a weak return. Strong returns indicate rough surfaces or slopes that point back at the radar, while weak returns come from smooth surfaces or slopes angled away from the radar. Over time, expansion of the summit eruptive vent within Halema‘uma‘u crater and the widening of Halema‘uma‘u itself are obvious. Starting in late May, the development of several cracks outside Halema‘uma‘u is clear, and inward slumping of a large portion of the western, southwestern, and northern crater rim begins. Much of this motion appears to be coincident with the small explosions from the summit that have taken place on a near daily basis since early June. The most recent radar scene, from July 4, shows continued motion along cracks over a broader area of the caldera floor, extending east of Halema‘uma‘u (these cracks are the scarps seen in recent photographs from the Keanakākoʻi overlook area). We expect this slumping to continue as long as the collapse events and overall subsidence persist.

Kilauea Eruption: Lava flow continues, community meeting at Cooper Center tonight Thursday (July 5)

USGS scientist observes the glow of fissure 8 fountain and channel within Leilani Estates. Steam rises from cracks and hot spots within the tephra deposit surrounding the cone. Frequent observations of the cone and channel are made throughout the day and night to track changes that could lead to signfiicant breakouts beyond the current flow field.

Fountains from Fissure 8 spatter cone continue to supply lava to the open channel with intermittent small, short-lived overflows. Overflows appear as lighter gray to silver areas on the margins of the channel. A larger of active overflow can be seen in the upper right of the photograph.

High-resolution satellite data are useful for mapping cracks and deformation in the summit caldera at Kīlauea Volcano. This map shows major fractures in yellow (as of June 29) on a base image acquired by the WorldView-2 satellite before the current sequence of events began at Kīlauea. The area of major subsidence has expanded east and south, and slightly west, of the main Halema‘uma‘u crater area. The large, red-shaded area east of Halema‘uma‘u is moving down within a scarp-bounded area, as seen in recent photographs of the summit. Some fractures have also formed to the east-northeast of the red-shaded area of accelerated motion, and also on the south caldera rim where parts of the caldera wall have slumped into the rapidly moving caldera floor below. The dark gray-shaded area within the red shaded area shows the region of most significant down dropping and is currently the deepest part of Kīlauea caldera.

Lava from fissure 8 is fed into a channel that travels about 13 km (8 mi) to the sea. A plume marks the location of fissure 8, visible in the upper right; a small plume in the upper center marks the location of fissure 22. Each morning, HVO field crews conduct an overflight of the lava channel to determine if there have been any overflows. Intermittent small, short-lived overflows have occurred, but these overflows rarely extend beyond the existing flow field. Photo taken Saturday, June 30, 2018 courtesy of U.S. Geological Survey
