Kilauea ocean entry hazards: The plume is not your friend

| | Sep 19 2016 - 2:51pm | Comments

Recent visitors to the Kamokuna ocean entry have been greeted with the spectacular sight of Kilauea’s lava pouring into the sea to form some of the newest land on Earth. The vigorous interaction between molten lava (2,000 degrees Fahrenheit) and relatively cool seawater (around 80 degrees Fahrenheit) seldom fails to capture the imagination and engage the two particular senses of hearing and sight.

    KALAPANA — Smoke from burning trees and open channels of lava could easily be seen Tuesday from Kalapana as the lava flow from Kilauea’s Pu‘u ‘O‘o vent traveled down Pulama pali.

    The latest lava flow from Kilauea’s Puu Oo vent has begun to peek over the pali, providing curious onlookers an early glimpse of its glow from Kalapana.

    Kiluaea Volcano’s Puu Oo vent continues to feed the latest lava flow advancing toward Pulama pali on Monday.

    In 1823, the party of English Rev. William Ellis (1794-1872), including American missionary Asa Thurston and a number of local guides, explored the wild landscape of Kilauea Volcano. Ellis returned with his ailing wife to a family home in London where, in 1824, he began writing a detailed narrative of his journey around the Hawaii Island. No other Caucasian visitors had published descriptions of this landscape, and one could say that the “history” of Ka‘u and, more broadly, of Kilauea, in the sense of contemporary written documentation, begins with Ellis.

    Early May 24, USGS Hawaiian Volcano Observatory scientists were alerted by text message that a tiltmeter on the Puu Oo cone on Kilauea Volcano’s East Rift Zone had detected rapid change. Soon after, an HVO field crew reported that lava had broken out from the flanks of Puu Oo. Tiltmeter data showed that the breakout likely began at 6:50 a.m.,resulting in a rapid deflation of the cone as magma burst forth from new vents.

    The lava flow that menaced Pahoa and the rest of lower Puna has come to an end.

    During the past 148 years, Mauna Loa Southwest Rift Zone eruptions have sent massive lava flows across Hawaii Island’s main road six times: in 1868, 1887, 1907, 1919, 1926, and 1950. These flows destroyed villages, displacing residents; burned forests and ranch land, trapping cattle on isolated knolls; blocked roads, disrupting traffic; and torched telephone poles, severing communication.

    In his popular single “Volcano,” Jimmy Buffett sings, “I don’t know where I’m a gonna go when the volcano blow.” His lyrics referred to Soufrière Hills, a then-dormant volcano on the island of Montserrat in the West Indies, where he recorded the song in 1979. Sixteen years later, the volcano erupted for the first time in over 400 years.

    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.
