This thermal image shows the western portion of the West Ka‘ili‘ili ocean entry, which hosts numerous small entry points. Active breakouts can be seen on the coastal plain along the west margin of the flow field.

This near-vertical view from the helicopter shows the surface of the lava lake at Halema‘uma‘u.

One of the individual streams of lava cascading over the sea cliff, producing a thick steam plume at the water's edge.

This skylight provided a clear view of the lava stream inside the lava tube on today's overflight, and a swiftly moving current could easily be seen.

This image of a dusty plume produced by rocks collapsing from the wall of the eruptive vent within Kīlauea Volcano’s Halema‘uma‘u Crater was captured by a USGS time-lapse camera on December 21, 2011.  Vigorous spattering on the lava lake deep within the vent created the orange glow visible at the base of the plume.

On December 4, at 9:20 a.m., a collapse in the Halema‘uma‘u vent turned the plume a dusty-brown color and deposited a thin layer of ash on the road downwind of the vent. Forty minutes later, at 10:00 a.m., the plume was greatly diminished. Since this December 4 event, the plume has been small and wispy, except when heavy rains cause an increase in steam.

Footprints made in muddy ash during Kīlauea's 1790 eruption are reminders that people experienced the largest explosive eruption in Hawai‘i in 1,000 years. Several hundred, and possibly more than a few thousand, people were killed by the eruption soon after the footprints were made.

Views of the east wall of Halema‘uma‘u crater on March 10 and 13, 2008, showing the emergence of a new gas vent. The Halema‘uma‘u crater overlook is circled. Note the large gas plume in the right frame taken on March 13, 2008.

View looking southwest of the Pu‘u ‘Ō‘ō cone and crater. The fume sources on the northeast flank (lower left) mark the path of the lava tube that is feeding flows on the pali. The vent feeding the tube is the fuming area near the crater rim (center); an active circular lava pond is immediately behind the vent.

Close view of the Pu‘u ‘Ō‘ō crater. Incandescent spatter cone stands above fume rising from the main vent area. Lava is still erupting in the lava pond, marked by the smooth shiny surface behind the spatter cone, but the level appears to have stabilized overnight.

Lava spilling down the steep pali this morning formed many small channels and ‘A‘ā flows. Many such flows were visible on the pali overnight.

pāhoehoe flows spreading on the coastal plain about 0.6 km from the base of the pali. When visited this morning, the flows had spread out considerably as they filled in low areas of the coastal plain. The leading edge of the flows were about 2.5 km from the ocean.

The current lava flow, coming down the pali and traversing the coastal plain, reached the ocean late last week. The ocean entry point is within the National Park, near its eastern border. Today, numerous small streams of lava were cascading over the sea cliff, and lava entering the water was starting to build a small delta.

This photograph shows two channels of lava coming over the sea cliff, reaching the new lava delta.
