    All About Hawai'i Volcanoes and Earthquakes
    The Big Island of Hawai'i is composed of five volcanoes... Kohala, Mauna Kea, Hualālai, Mauna Loa, and Kilauea.

    Hualālai and Mauna Loa are expected to erupt again. Mauna Kea can still be active though there are no current indications. The current active volcano is Kilauea which has been spewing forth lava pretty much nonstop since it began - and is among the worlds most active volcanoes.

    Currently lava comes out at the Pu'u 'O'o vent inside the Hawai'i Volcanoes National Park. Depending on conditions the lava is quite often accessible and offers visitors an experience of a lifetime.

    Lava flowing from Pu'u 'O'o normally flows through lava tubes towards the ocean 6 miles away. About two miles before the ocean the lava encounters a 1,200 foot cliff which is flows over, and then two to three miles of coastal flats until it pours into the ocean. Often the lava is visible on the Pali (cliff), on the coastal flats, and at the ocean entry.

    In the huge Kilauea Summit caldera itself site Halema'uma'u Crater. On March 19, 2008, a vent opened in the crater causing a portion of Crater Rim Drive to be closed. The vent is still open but lava continues to remain below the surface of the vent.

    We have much to say about the volcano and the lava - this page lays out the various sections that you can visit.

    Be sure to read the section on Cautions and Warnings as it contains very important information about volcano safety.

    Current Volcanic Activity

    The USGS Hawaiian Volcano Observatory located in the Hawai'i Volcanoes National Park provides a daily update of the eruption activity at Pu'u 'O'o and down on the coastal flats. This is a good place to check to see what is currently going on.

    We extract the daily report from USGS and have it for you below along with some of the most recent USGS pictures of the flow. Please visit the USGS website for more details and photographs.

    HAWAIIAN VOLCANO OBSERVATORY WEEKLY UPDATE
    U.S. Geological Survey
    Tuesday, December 11, 2018, 9:56 AM HST (Tuesday, December 11, 2018, 19:56 UTC)


    KILAUEA VOLCANO (VNUM #332010)
    19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
    Current Volcano Alert Level: ADVISORY
    Current Aviation Color Code: YELLOW

    Activity Summary: Kīlauea Volcano is not erupting. Rates of seismicity, deformation, and gas release have not changed significantly over the past week. Deformation signals are consistent with refilling of the middle East Rift Zone.

    Observations: HVO monitoring during the past week showed no significant changes. Geologic web cams observed gusty winds lofting and remobilizing some of the ash at the summit of Kīlauea. Low rates of seismicity at the summit and East Rift Zone (ERZ) continue, with events occurring primarily at Kīlauea's summit and south flank areas. In the ERZ, tiltmeters showed little change over the last week, with GPS indicating some inflation downrift from Puʻu ʻŌʻō. At the summit, tiltmeters recorded one DI (deflation-inflation) sequence in the middle of last week, with minor fluctuations in tilt through the rest of the weekend. Sulfur dioxide emission rates have been below detection limits in the LERZ since early September, though minor amounts of volcanic gas are still present. Sulfur dioxide emission rates were last measured at ~35 t/d at both the summit and ERZ, consistent with the past few months of emissions from Kīlauea.

    Hazards are still present in the LERZ eruption area and at the Kīlauea summit. Residents and visitors near recently active fissures and lava flows should stay informed, heed Hawaii County Civil Defense and National Park warnings, and be prepared, if necessary, to self-evacuate in the unlikely event of renewed activity. Please note that Hawaii County maintains a closure of the entire flow field and the vents and prohibits access to the area unless authorized through Civil Defense.

    The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea's seismicity, deformation, and gas emissions for any sign of reactivation, and maintains visual surveillance of the summit and the East Rift Zone. HVO will continue to issue a weekly update (every Tuesday) and additional messages as warranted by changing activity.
