Kilauea Eruption Update

Map as of 12:00 p.m. HST, July 2, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

This thermal map shows the fissure system and lava flows as of 6 am on Monday, July 2 The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Small flows were observed today near Fissure 22. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.

USGS, Kilauea Volcano Eruption, Lava scenes from “Fissure 8” and the ocean entry zones, June 29, 2018


In the Leilani Estates subdivision, Hawaiian Volcano Observatory field crews monitoring fissure 8 captured this video of a whirlwind above the lava channel. The vortex of rapidly swirling air entrained hot lava, flinging it meters away. The scientists maintained a safe distance, using a telephoto lens to take this video. The whirlwind lasted about 10 minutes, starting and stopping without warning.


On June 30, 2018, at 02:51 PM HST, a collapse/explosion event occurred at Kīlauea’s summit. An ash-poor plume rose about 150 m (500 ft) above the ground and drifted to the southwest. The energy released by the event was equivalent to a M5.3 earthquake. This video, taken by a USGS observer at Volcano House, captures rockfall (brown dust visible in the center right) along the bluff and a small plume rising from the Halema‘uma‘u crater. Since May 16, these collapse/explosion events have occurred on average, about every 28 hours. As magma from the shallow reservoir beneath the summit drains into the East Rift Zone, it slowly pulls away support of the rock above it. The crater floor responds by incrementally collapsing, which produces these events.

This is a Civil Defense Message for 6 p.m., Monday, July 2, 2018.

Hawaiian Volcano Observatory reports that Fissure 8 continues to be very active and is feeding a lava channel to the ocean at Kapoho. The flow is producing a broad ocean entry along the shoreline and is also oozing fresh lava at Kapoho Beach Lots. Fissure 22 is also active and producing a short flow.  Gas emissions from the fissure eruption and laze at the ocean entry continue to be very high. The National Weather Service reports trade winds will push vog to the south and west side of the island.

Highway 130 will re-open to all traffic beginning at 8 a.m. tomorrow, July 3.

  • Kamaili Road will be open to residents only
  • Highway 137 will be open from Highway 130 north to Opihikao road
  • McKenzie State Recreation Area and the new lava flow areas remain closed
  • Vacation Rentals, as well as all businesses in the Kalapana area, can resume normal operations

There will be a community meeting tomorrow at 5 p.m. at the Pahoa High School cafeteria.

The Pahoa Post Office is open during normal business hours with temporary Sunday hours from 10 a.m. to 2 p.m. for mail and package distribution only for residents in the affected areas. No retail services on Sunday.

For your safety, heed warnings from Civil Defense officials and stay alert.

Ocean entry laze

Due to the lava entry at the ocean, the following policies are in effect:

  • Access to the area is prohibited due to the laze hazard.
  • Stay away from any ocean plume since it can change direction without warning.
  • The U.S. Coast Guard is actively monitoring the ocean entry area and enforcing a 300-meter standoff zone. Only permitted tour boats are allowed in the area.
  • Health hazards of laze include lung, eye and skin irritation.
  • Be aware that the laze plume travels with the wind and can change direction without warning.

Sulfur Dioxide (SO2) and Vog

Volcanic gas emissions remain elevated throughout the area downwind of the vents in lower Puna.

  • Severe conditions may exist such as choking and inability to breathe.
  • Sulfur Dioxide (SO2) gas from fissures are especially dangerous for elderly, children/babies and people with respiratory problems.

County, State, and Federal partners continue to monitor the situation. You will be informed of any conditions that affect your safety.

Monitor vog levels and forecasts: People on Hawaii Island outside the area of volcanic activity are also advised to monitor levels of vog at vog.ivhhn.org

The residents of Puna are going through a very difficult time. We ask for your help and understanding.

Illustration of Kīlauea Volcano from the summit caldera to the lower East Rift Zone (LERZ). Blue arrows = contraction across the upper and middle rift zone, black arrows = expansion in LERZ. Blue arrows indicate contraction across the upper and middle rift zone as magma withdrew from this area and moved down the rift zone beginning on April 30, 2018. Black arrows indicate expansion across the rift zone as magma intruded into the LERZ; the widening on about May 18, 2018. Also, beginning in early May, magma began moving from the summit reservoir into the East Rift Zone. Data sources used in this modeling are from the U.S. Geological Survey/ University of Hawaii, NASA, Jet Propulsion Laboratory, Japan Aerospace Exploration Agency/ and the European Space Agency.
