19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Activity Summary: Eruptions continue at Kīlauea Volcano's summit and East Rift Zone. The summit lava lake level rose slightly overnight as summit tiltmeters continued to record inflationary tilt. Puʻu ʻŌʻō cone continues the inflationary trend of the past several weeks, and the Episode 61g lava flow is active above Pulama pali. The flow does not pose a threat to nearby communities at this time. There is currently no active lava on the pali, the coastal plain, or entering the ocean.

Summit Observations: Summit tiltmeters recorded inflationary tilt during the past day. When measured yesterday afternoon, the lava lake level was about 14 m (46 ft) below the rim of Overlook crater; the level had risen 11 meters (36 ft) from the previous day. The lava lake continued to rise overnight by a few meters (yards). Seismicity in the summit area is within normal, background rates, with tremor amplitude fluctuations associated with lava lake spattering. Elevated summit sulfur dioxide emission rates persist.

Puʻu ʻŌʻō Observations: Inflationary tilt continues to be recorded by a tiltmeter at Puʻu ʻŌʻō, continuing the inflationary trend of the past several weeks. Good weather On Tuesday morning allowed geologists to observe changes at the west pit lava pond—overflows of the pond have built it several meters (yards) above the west pit floor. The pond level was 7 m (23 ft) higher than it was in late March. This is consistent with the overall inflationary trend and uplift of the main crater floor at Puʻu ʻŌʻō. Webcam views showed no new flows in the crater in the past 24 hours. Seismicity is at normal, background levels. 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: There is no lava flow activity from the Episode 61g lava flow on the coastal plain or pali, and no lava is flowing into the ocean. Lava flow activity continues on the upper flow field, above the pali and closer to Puʻu ʻŌʻō, and does not pose a threat to nearby communities at this time. Areas of the upper flow field with active lava flows are located within the Kahaualeʻa Natural Area Reserve, which has been closed to the public by DLNR since 2007 due to volcanic hazards. Webcam views of the flow field are available here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_webcams.html. Maps of the lava flow field can be found here: https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html.

Lava Flow Field and Ocean Entry Hazards: The current location of active surface lava is not accessible to hikers and is predominantly in a closed area. Hikers and visitors to the lower Puʻu ʻŌʻō lava flow field should be prepared for a variety of hazards, including, but not limited to: hard, rough, uneven and sharp terrain, which can lead to falls, abrasions, lacerations, and other injuries, as well as heat exhaustion or dehydration. Heavy rains can occur with little warning, producing a steamy ground-fog on recent flows that severely limits visibility. This steam can be acidic and should be avoided.

No services are available on the lava flow field and cell reception is limited.

Please consult safety information at these links before heading out and heed all posted signs:

Though inactive at present, the 2016-2017 lava delta remains potentially unstable, and collapse of some or all of the delta without warning is possible. In several instances, collapses have also incorporated parts of the older sea cliff. Explosions of rocky debris remain possible should collapses suddenly expose the hot interior of the inactive lava delta.

A virtual flyover of Pu‘u ‘Ō‘ō

This video shows a virtual flyover of Pu‘u ‘Ō‘ō, the active vent on Kīlauea's East Rift Zone. The 3-D model was constructed from thermal images collected by USGS Hawaiian Volcano Observatory geologists during a helicopter overflight on April 18. In this model, the active lava pond in west pit, a small crater adjacent to the main Pu‘u ‘Ō‘ō crater, appears hotter (bright yellow) than the surrounding area. The floor of the main crater has been uplifting due to increasing pressure within the magma system beneath Pu‘u ‘Ō‘ō. For scale, the main crater is about 280 m (920 ft) in diameter.
