Beyond volcanoes and earthquakes: USGS scientists study mosquito ecology on Hawaii Island

Today’s Volcano Watch is courtesy of our U.S. Geological Survey colleagues at the Pacific Island Ecosystems Research Center, which focuses on Hawaii’s biodiversity.

    In early November, volcano scientists from Hawaii, Chile, Indonesia, Italy and Japan participated in a workshop at the Mount Fuji Research Institute in Japan. Talks and discussions during the workshop were focused on the best ways to protect tourists in active volcanic areas.

    The surface of Kilauea volcano is rarely stationary. There are a variety of processes that each move or change the shape of the volcano and, when active at the same time, create a complex pattern of ground deformation. Satellite-based Interferometric Synthetic Aperture Radar (InSAR) has become a key tool during the last two decades to illuminate this complexity.

    One of the wondrous things about visiting a young lava flow on Hawaii Island is encountering the tenacious plant life that emerges from a barren and rough volcanic environment. Volcanophile hikers know that taking a tumble on the sharp, glassy lava surface can leave a lasting impression. Yet, within a few years, a recent lava flow can host a community of plants that includes ohia lehua (Metrosideros polymorpha) — one of the most common trees in Hawaii and the first native tree to colonize young lava.

    A lot has changed over the past year on Kilauea Volcano. One year ago, the June 27 flow was threatening to cross Pahoa Village Road and, potentially, Highway 130. Lava destroyed one house on Nov. 10, 2014, and was moving downslope toward many others.

    One year ago, the now infamous June 27 lava flow was headed toward the middle of Pahoa and threatening to cross the main village road and cut off Highway 130 for thousands of residents. During this time, the U.S. Geological Survey’s Hawaiian Volcano Observatory was forecasting that, if the flow continued, it could also cut Kahakai Boulevard and overrun Keonepoko Elementary School.

    It happened again. Did you notice? Last week, a portion of Kilauea Volcano’s south flank slowly slipped seaward. Its movement is part of a recurring phenomenon called a “slow earthquake,” which last occurred on Memorial Day 2012.

    Geologic mapping is considered by some to be “old school” science. By current standards, there’s certainly nothing glitzy or high tech about walking miles across seemingly barren rock or through dense forests to map lava flows.

    Thursday is the third annual Great Hawaii ShakeOut. That day also marks the ninth anniversary of Hawaii’s two most recent damaging earthquakes.

    Hawaii has a long history of destructive earthquakes. More than 30 magnitude-6.0 or greater earthquakes have impacted the islands since 1868 (or about once every five years), and the chance of a damaging earthquake striking Hawaii in the next 10 years is 50 percent.

    Bottled soda, when opened suddenly after shaking, is commonly used as an analogy for volcanic eruptions. Perhaps the first use of this analogy for Hawaiian volcanoes was during the 1899 Mauna Loa eruption, when Sereno Bishop, a missionary with an interest in science, suggested the idea in a letter to the Hawaiian Star newspaper on July 20.

    The U.S. Geological Survey Hawaiian Volcano Observatory changed the Volcano Alert Level and Aviation Color Code for Mauna Loa Volcano from normal/green to advisory/yellow on Thursday. This change reflects HVO’s determination that the volcano is showing persistent signs of low-level unrest. It does not mean, however, that an eruption is imminent or certain.

    During the 1950s, a decade of major change in volcano monitoring, the U.S. Geological Survey’s Hawaiian Volcano Observatory was moving from the mechanical into the electronic age, and staff were needed who could fulfill the requirements of the new technology.

    From “watch” to “warning” and back: Kilauea Volcano’s status changes during past year

    Does lava continue to flow exactly as it did on land or does it behave differently after it enters the ocean?

    A large breakout early Thursday erupted lava onto the floor of Puu Oo Crater, U.S. Geological Survey Hawaiian Volcano Observatory reports.
