Volcano Watch: Thermal cameras keep a cool eye on hot lava

| | Aug 12 2017 - 8:53pm | Comments

Thermal cameras have been used by volcanologists around the world for many years to study volcanic processes and search for signs of impending eruptions.

    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.

    In early 1918, visitors swarmed to Kilauea Volcano to see a splendid show. The molten lake in Halemaumau had been rising and the pit was almost full. Soon lava spilled over the crater rim onto the floor of Kilauea’s summit caldera, destroying part of an automobile road, as well as the visitor viewing area near the rim.

    As part of our monitoring of subsurface activity at Mauna Loa, we recently conducted a series of measurements of the force of gravity at various locations near the summit caldera and rift zones of the volcano. Did that sentence surprise you? Most of us don’t think much about gravity, but when we do (as in, perhaps, cursing it when our cellphone drops to the ground), we don’t usually think of it as being different from place to place or from time to time.

    For 15 years, we’ve been on a journey of discovery through Kilauea’s volcanic past. Today, we review what’s been learned on that journey and how new findings are shaping our thoughts about the future at Kilauea.

    The June 27 lava flow remains active within 5 miles of the Puu Oo vent, U.S. Geological Survey Hawaiian Volcano Observatory scientists said Friday.
