Today, Kīlauea Volcano's summit lava lake level was 21 m (69 ft) below the vent rim. A long stretch of active spattering was visible along the east lake margin from the rim of Halema‘uma‘u Crater, an area that remains closed to the public due to ongoing hazards. The usual spatter source to the southeast was small by comparison.

A telephoto view of the east lake margin showed that the spattering was focused in small embayments created by promontories of cooled, congealed lava jutting from the vent wall.

The 61g flow breakout that started on February 10 on Pulama Pali was still active today. The flow front (shown here) is approximately 2.3 km (1.4 mi) from the base of the pali and 1.2 km (0.75 mi) from the ocean. The flow front is on the eastern side of the 61g flow field, and is outside the National Park boundary.

At the coast, the lava flow in the Ahalanui area remains less than 0.1 miles from the Pohoiki boat ramp (left of center in this photo) in Isaac Hale Park. The active ocean entry is a few hundred yards east (right) of this photograph.

NASA ER-2 aircrafts have played an important role in Earth science research because of their ability to fly into the lower stratosphere at subsonic speeds, enabling virtual satellite simulation missions.

The "firehose flow" at Kīlauea Volcano's Kamokuna ocean entry was clearly visible from the public lava viewing area established by Hawai‘i Volcanoes National Park. The viewing area is 800 meters (about one-half mile) from the ocean entry, but affords excellent views of the lava flow.

VIDEO: The section of sea cliff above the ocean entry collapsed today at about 12:55 p.m. The sea cliff had become increasingly unstable as a large crack 5-10 m (16-33 ft) inland of the ocean entry had more than doubled in width, from 30 cm (1 ft) to 70 cm (2.5 ft), over the past several days.

HVO geologists hiked to the Kamokuna ocean entry today to assess the status of the sea cliff. When they arrived, the "firehose" flow was no longer visible. However, spatter (bits of molten lava) and black sand flying through the steam plume indicated that lava was still flowing into the ocean and interacting explosively with seawater.

Within minutes of HVO geologists reaching the ocean entry site, the sea cliff seaward of the hot crack (see Jan. 30 images) collapsed with no warning; fortunately, they were far enough away to not be in harm's way. The top photo was snapped just before the collapse occurred. The bottom image shows the remaining sea cliff after the collapse.

The entire section of the sea cliff that was seaward of the hot crack collapsed, except for a small block of rock (left) at the eastern end of the crack; this piece of the sea cliff, estimated to be 30 m long and 5 m wide (98 x 16 ft), remains highly unstable and could collapse with no warning.

Detailed views of the "firehose" flow streaming from the lava tube, spatter, and rock fragments were provided by zooming the telephoto lens in even closer.

This image comparison shows the changing nature of the lava stream between Saturday, January 28 and Wednesday, February 1. The lava stream has become much more narrow, as viewed from this angle.

From the lava viewing area established by Hawai‘i Volcanoes National Park, you can witness Kīlauea Volcano's ocean entry from a safe distance. With binoculars or a telephoto camera lens, spectacular views and photos are possible (as seen here)—without risking your life by entering the closed area.

Using a telephoto lens, spatter and glassy rock fragments (black sand) from the explosive interaction of molten lava and seawater can be seen flying skyward and seaward. At times, these fragments were thrown high enough to land on the sea cliff above the ocean entry—one of many hazards impacting this area.
