Activity Summary: Kīlauea Volcano continues to erupt at its summit and at the Puʻu ʻŌʻō vent on its East Rift Zone. The episode 61g lava flow from Puʻu ʻŌʻō is entering the ocean at Kamokuna and is feeding surface flows on the pali and the coastal plain, inland from the ocean entry. These lava flows pose no threat to nearby communities at this time. There was no change in tilt at the summit, and the lava lake surface was 18.5 m (~61 ft.) below the floor of Halemaʻumaʻu Crater this morning.
Summit Observations: Tiltmeters at Kīlauea's summit recorded no significant change in tilt over the past day. In other words, there was no significant inflation or deflation. The lava lake surface was measured at 18.5 m (~61 ft.) below the rim of the Overlook vent (i.e., the floor of Halemaʻumaʻu Crater) this morning. Webcam views of the lava lake can be found at this webpage: http://hvo.wr.usgs.gov/cams/region_kism.php. Seismicity is within normal, background rates, with several small earthquakes occurring across the volcano, and summit tremor fluctuations associated with lava lake spattering. Average daily summit sulfur dioxide emission rates ranged from about 1,800 to 2,600 metric tons/day for the few days over the past week when conditions permitted measurements.
Puʻu ʻŌʻō Observations: Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from a vent high on the northeast flank of the cone. There were no significant changes in seismicity over the past 24 hours. The tiltmeter recorded no significant change in tilt. The sulfur dioxide emission rate from all East Rift Zone vents was about 200 metric tons/day when last measured on February 16, 2017.
Lava Flow Observations: The episode 61g flow is still active and entering the ocean at Kamokuna. It also hosts weak surface breakouts on the coastal plain less than 1 km (~0.6 mi) upslope from the FEMA emergency road. Other surface flows are streaming down the pali farther inland. None of these flows pose a threat to nearby communities at this time.
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 the 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. In several instances, such collapses, once started, have also incorporated parts of the older sea cliff. This occurred most recently on December 31. 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.

February 8, 2017 - "Firehose Flow" Visible From Public Lava Viewing Area
The "firehose flow" at Kīlauea Volcano's Kamokuna ocean entry was clearly visible from the public lava viewing area established by Hawaiʻi Volcanoes National Park. The viewing area is 800 meters (about one-half mile) from the ocean entry and affords excellent views of the lava flow.
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.
Video of the lava lake splashing and sloshing inside Halema‘uma‘u Crater at the summit of Kīlauea in Hawaii Volcanoes National Park on the evening of Sept. 7, 2016. This video was filmed by Sami Steinkamp, an intern with the Student Conservation Association's Centennial Volunteer Ambassador program. Sami was at the Jaggar Museum observation deck, about a mile from the eruption site, the closest visitors can get.

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.
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 January 12 is shown in pink, while widening and advancement of the active flow as of February 16 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) are shown in gray. The yellow line marks the trace of the active lava tube (dashed where uncertain).
July 3, 2016 - County of Hawai‘i Civil Defense Agency Press Release(pdf 110KB) The County of Hawai‘i has opened the emergency road on the Kalapana side for lava viewing since Thursday, June 30, 2016, between the hours of 3:00 pm to 9:00 pm daily. This is outside Hawai‘i Volcanoes National Park and managed by the County. Please read the entire press release for more information.
Kalapana viewing area status (recorded message): 808-430-1966
Directions to Kalapana from Hawai‘i Volcanoes National Park: Take Hwy 11 towards Hilo to Hwy 130. Follow Hwy 130 until you reach the road's end and the visitor parking area. (45 miles).
