Volcano Watch: The ongoing Puu Oo eruption is full of anniversaries

| | Aug 19 2017 - 2:22am | Comments

The longest-lived and most voluminous rift-zone eruption of Kilauea Volcano in more than 500 years — the ongoing Puu Oo eruption — began in January 1983, and is fast approaching its 35th anniversary. So many lava flows, cones, deltas, and other features have formed from eruptions at different vents for varying periods of time that nearly every day is an anniversary for Puu Oo.

    In past Volcano Watches, we’ve emphasized a radically new way to view Kilauea — as an explosive volcano. Though not explosive now, it was dominantly explosive during 60 percent, or 1,500 years, of the past 2,500 years. Its latest major period of explosiveness lasted 300 years between the dawn of the New World and the Napoleonic era, which ended in 1815.

    At the U.S. Geological Survey’s Hawaiian Volcano Observatory, we focus on keeping up with the flow of data coming into our systems and servers from HVO’s monitoring networks and instruments. But we also take time each November to recognize the anniversaries of two significant Hawaiian earthquakes that are both important to remember, even as we pore over new data.

    We are currently sandwiched between the Halloween and Thanksgiving holidays as the inexorable march of time brings the winter festivals ever closer. For Hawaii, this period also signals the time of year when interruptions in the trade winds become more common.
