Activity Summary: No significant change. Kīlauea Volcano continues to erupt at the summit and at Puʻuʻōʻō vent on the East Rift Zone. The episode 61g lava flow from Puʻuʻōʻō is entering the ocean at Kamokuna. Surface flows are active above the pali, but pose no threat to nearby communities. The summit lava lake surface is more than 30 m (98 ft) below the floor of Halemaʻumaʻu this morning. There have been no significant changes in seismicity levels or ground deformation trends across the volcano.
Summit Observations: Tiltmeters at Kīlauea's recorded the start of deflation at about 6 pm last night and the lava lake level dropped to more than 30 m (98 ft) below the rim of the Overlook Vent but wasn't measured this morning because of high winds in the area. Webcam views of the lava lake can be found at: http://hvo.wr.usgs.gov/cams/region_kism.php. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. Summit sulfur dioxide emission rates remain high.
Puʻuʻōʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a small lava pond on the west side of the crater. There were no significant changes in seismicity over the past 24 hours. The tiltmeter near Puʻuʻōʻō crater recorded modest inflationary tilt over the past day. The sulfur dioxide emission rate from the East Rift Zone vents has been steady over the past several months and remains significantly lower than the summit emission rate.
Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. Near Puʻuʻōʻō, flows continue on the upper portion of the flow field. These flows do not pose any threat to nearby communities at this time.
Ocean Entry Hazards: As a strong caution to visitors viewing the ocean entry (where lava meets the sea), there are additional significant hazards besides walking on uneven surfaces and around unstable, extremely steep sea cliffs. Venturing too close to an ocean entry on land or the ocean exposes you to flying debris created by sudden explosive interaction between lava and water. Also, the new land created is unstable because it is built on unconsolidated lava fragments and sand. This loose material can easily be eroded away by surf, causing the new land to become unsupported and slide into the sea. This occurred most recently on May 3. In several instances, such collapses, once started, have also incorporated parts of the older sea cliff. Additionally, the interaction of lava with the ocean creates a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.
USGS - Hawaiian Volcano Observatory - Following the December 31, 2016, lava delta collapse at Kīlauea Volcano's Kamokuna ocean entry, lava continued to flow into the sea without building a new lava delta, most likely because the lava was cascading down a steep offshore slope to deeper parts of the ocean. But in late March 2017, a new delta finally began to form, although it was obscured by steam during HVO's March 30 overflight (left photo). The thermal image at right shows lava streaming into the ocean from the leading edge of the delta (bright yellow area in center of image) and the adjacent heated seawater (discolored water in the photo). It also shows the trace of the active lava tube that carries lava from the vent to the sea (right side of image), as well as small breakouts of lava along the tube and surface flows near the Puʻu ʻŌʻō vent (top of image).

March 30, 2017 - The episode 61g flow continues to enter the ocean at the Kamokuna ocean entry (center), and was producing a robust plume. The western Kamokuna delta, which was abandoned in late September 2016, is visible to the left of the entry. A few weak surface breakouts were still active on the coastal plain, but most surface activity is within approximately 3.5 km (2.2 miles) of the vent. The episode 61g tube is marked by fume traces that can be seen along the flow field, and Puʻu ʻŌʻō is visible in the center of the skyline. Link to full resolution photo (opens in new window).

The section of sea cliff above the ocean entry collapsed February 2, 2017 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. A video camera, which had just been set up to monitor movement of the crack near the sea cliff, captured the moment of collapse.

Hawai‘i Volcanoes National Park Lava Flow Updates
The 61G lava flow, southeast of Puʻu ʻŌʻō, continues to stream down the Pulama Pali onto the coastal plain of Kīlauea volcano's East Rift Zone into the ocean. The actual flow is moving slowly and many breakouts were active upslope and widening the flow field. Bright incandescence remains visible on the active lava flow field, marking areas of active breakouts.
Park rangers have set up a Coastal Ranger Station (CRS) at the end of Chain of Creaters Road with eruption update, hiking and safety tip exhibits, and a monitor that plays a four-minute lava safety video. Visitors are strongly urged to stop and talk with rangers and review all signage and watch the video at the CRS. The CRS is staffed daily and in the evening during peak visitation hours. The park is open 24 hours a day.

Hiking out to the lava flow from the park is allowed, but it's not for everyone. From the CRS, it's a grueling, 7.4 mile roundtrip hike. Hikers may walk along the gravel emergency access route for the majority of the hike.
All who attempt to hike out the lava flows are urged to prepare ahead and bring a 2-4 liters or quarts of water for every person in your party, sun protection, a hat and wear strong hiking boots or shoes. If you hike out later in the day, ensure you have a good flashlight and extra batteries in case you are out after dark. Cell phone flashlights are not sufficient. See the safe hiking tips for additional information on proper footwear, clothing, and other important safety information.
Stay safe, and be very mindful of poor air quality. When plumes of hazardous volcanic gases (sulfur dioxide and hydrochloric acid) are blown along shore, they are a threat to your health. It is currently best to hike in from the County of Hawai'i lava viewing area on the Kalapana side to access the ocean entry. The Kalapana access is open daily from 3 p.m. to 9 p.m. It's about a 4.2-mile hike from the Kalapana boundary to the ocean entry viewing point, one way, along the gravel emergency access road.
The presence of volcanic gas increases the closer you get to the ocean entry. This is where the lava crossed the Chain of Craters emergency access road, hiking in from the park side (USGS vehicle). Notice how the plume is blown right over the coastal area and road

If you do hike in from the park side, be aware that the gases get stronger the closer you get to the ocean entry. Rangers have roped off the park side of the ocean entry and placed signs warning of the toxic fumes. Be aware that even in the open areas, volcanic gases are likely to be at unhealthy levels. Volcanic gases are a danger to everyone, particularly to people with heart or respiratory problems and infants, young children and pregnant women. Check with rangers at the end of Chain of Craters Road about current conditions before you head out, review the exhibits, and obey all closures and signs. You can head inland to avoid the fumes, and hike until you get upwind of the ocean entry fumes.
Volcanoes are dynamic and ever-changing natural phenomena. The flow information, distances, and other lava information provided here can change at any time.
Experienced bicyclists may use the gravel emergency access route during the day. It is not recommend to ride bikes on the loose gravel after dark. Motorized bicycles are prohibited.
Respect the Hawaiian culture. Do not poke lava with sticks or other items. Do not roast marshmallows or cook foods. To many Hawaiians, molten lava is the kinolau, or body form, of volcano goddess Pele. In addition, it is a federal offense to remove, destroy, alter, deface, dig or disturb anything from its natural state in a national park. (36 CFR § 2.1)
Pets, motorized vehicles, unmanned aerial systems (UAS) and overnight camping on the flow field within the park are prohibited.
Visitors are advised to "slow down and go with the flow." Hiking to the current lava flows is a 6-8 hour adventure for most fit hikers. Adding a roundtrip drive from the west side of Hawai'i Island makes for a very long day, and is not recommended. Remember: Kīlauea is also erupting from its summit crater, Halema'uma'u. You can safely and easily observe the summit eruption from the observation deck at Jaggar Museum, which is open 24 hours a day.
December 12, 2016 - Closure of a portion of Eruption Area
Until further notice a portion of the area near the coastal lava flow known as 61g and described below will be closed by direction of the park Superintendant. The closure is based on the potential for airborne debris being projected up to 300 meters from a collapsing lava bench. Flying debris is a safety concern for the public and employees. This closure will be in effect until there is no longer a danger. Area to be closed: A 300 meter section within the boundary of Hawai‘i Volcanoes National Park that is marked with posted signs notifying the public of the closure, where possible will be augmented by a rope barrier. Due to the constant shifting of lava benches and ocean entries, this area is subject to change and is therefore only referred to by the current location of posted signs.
This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of May 31 is shown in pink, while widening and advancement of the active flow as of June 21 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983–2016) are shown in gray. The yellow line is the trace of the active lava tube (dashed where uncertain).
The blue lines over the Puʻu ʻŌʻō flow field are steepest-descent paths calculated from a 2013 digital elevation model (DEM), while the blue lines on the rest of the map are steepest-descent paths calculated from a 1983 DEM (for calculation details, see https://pubs.usgs.gov/of/2007/1264/). Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the blue lines on this map can be used to infer only approximate flow paths. The base map is a partly transparent 1:24,000-scale USGS digital topographic map draped over the 1983 10-m digital elevation model (DEM).
