Amber waves of … Pele’s hair?

The lava lake within Halemaumau Crater at the summit of Kilauea Volcano is creating a scene remindful of a messy barbershop floor, except that it’s acres and acres wide rather than a few square feet. The ground downwind of the crater is strewn with Pele’s hair, and it is almost impossible to avoid stepping on it.

    More than 31 years after Mauna Loa last erupted, sending lava within 4.5 miles of Hilo, the largest active volcano in the world is showing signs of unrest.

    The Hawaiian Volcano Observatory says two new lava flows on Kilauea’s Pu‘u ‘O‘o cone have made little progress since they erupted Tuesday morning.

    Lava began flowing in two directions from Kilauea’s Pu‘u ‘O‘o cone Tuesday morning.

    In September 2015, the USGS Hawaiian Volcano Observatory (HVO) raised the Volcano Alert Level for Mauna Loa from “normal” to “advisory” because of increased activity beneath the mountain’s summit caldera and upper Southwest Rift Zone (SWRZ). Importantly, the “advisory” level does not indicate that an eruption is imminent or certain. Rather, it means that one or more monitoring data streams are recording activity significantly above background levels. At the same time that earthquake rates increased, sensitive Global Positioning Satellite (GPS) instruments and satellite radar systems (InSAR) recorded ground swelling, which indicated that magma was moving into shallow levels beneath the volcano (a process called “inflation”).

    In our January 2005 Volcano Watch article, titled “First Photograph of Kilauea Volcano in the 60s,” we featured an old print found in the USGS Hawaiian Volcano Observatory (HVO) photo archives. Written on the back of it was the notation, “First view of volcano in the 60s.”

    The Island of Hawaii has recently lived up to its worldwide reputation as a beautiful and dynamic place that is frequently vulnerable to many natural hazards. These include hurricanes, earthquakes, tsunamis, floods, and wildfires, as well as eruptions that can send lava flows through communities and create widespread volcanic air pollution.

    Happy birthday to the Hawaii Island geologic map!

    Each year, Hawaii County residents likely feel dozens of earthquakes. They might readily agree that earthquakes are indeed part of living on the Island of Hawaii. But residents across the State of Hawaii, recently nudged by three small earthquakes, were gently reminded that they, too, live with earthquakes.

    Mauna Loa, the largest active volcano on Earth, is not erupting, but is stirring. Seismicity remains elevated above long-term background levels, and ground deformation indicates continued inflation of a magma reservoir beneath the volcano.

    The U.S. Geological Survey’s Hawaiian Volcano Observatory is excited to welcome geophysicist Brian Shiro to its team. Shiro is HVO’s new seismic network manager, a key position in charge of monitoring earthquakes, one of the most important tools we have for understanding active volcanoes. He replaces Wes Thelen, who transferred to the USGS Cascades Volcano Observatory.

    The ongoing eruption at Kilauea Volcano’s summit began on March 19, 2008. Since that time, Island of Hawaii residents have had to cope with the challenges of increased vog and its effects.

    U.S. Geological Survey Hawaiian Volcano Observatory Geologist Don Swanson was recently named as the recipient of two prestigious awards.

    Despite not being in the headlines, Mauna Loa continues to be in a state of unrest based on seismic and deformation monitoring data.

    At 9:23 a.m., Feb. 12 a magnitude-4.1 earthquake occurred beneath Kilauea Volcano’s south flank. But this is probably not news to many “Volcano Watch” readers. Shaking from the earthquake was felt throughout the Island of Hawaii, with reports to the USGS “Did you feel it?” website ( from as far away as Captain Cook and Holualoa on the west side of the island.

    In recent weeks, the USGS Hawaiian Volcano Observatory has received a number of calls from local residents saying essentially: “Hey, is something up with Kilauea’s eruptions? The plumes at Halemaumau and Puu Oo seem to be enormous lately.”
