    USGS has downgraded Kilauea's alert status from orange to yellow for both aviation and otherwise due to now significant activity for thirty days. They also note this:
    This change in activity marks the first time since 1986 that lava has not been active at Kīlauea's surface for a period of 30 or more days (The last long pause was 48.5 days between episodes 39 and 40 of the Puʻu ʻŌʻō eruption.) In the past 200 years, the volcano has experienced periods of quiet ranging from months to years with no eruptive activity. However, Kīlauea is one of the most active volcanoes in the world, and additional eruptions will occur.

    From the HVO site: "Kīlauea Volcano is not erupting." They haven't been able to say that in more than 30 years. But there's an inflationary trend.

    To paraphrase Arnold, "She'll be back."

    So will this be considered the end of the 1983 eruption?

    Probably not, unless the period of inactivity goes on for a year or two. I'd bet it won't. It's recharging.

    On the other hand....
    September 4 was the last time active lava was observed along the LERZ; tomorrow (December 5) will mark three months with no eruptive activity at the surface. According to the Smithsonian Institution's Global Volcanism Program (https://volcano.si.edu/), volcanoes with no eruptive activity over a three-month period are no longer classified as having a "continuing" eruption. Based on this Global Volcanism Program criterion, the LERZ eruption could be considered to be over. However, there is one known example (Mauna Ulu, 1969-74) in which Kilauea's rift zone activity resumed after more than three months had passed. Although this phase of Kīlauea's activity has now reached this three-month threshold, it is important to note that it is still an active volcano that could erupt in the near future and associated hazards have not changed. Magma is being supplied to Kīlauea and geophysical datasets continue to show evidence for movement of material through the magma system, including the refilling of the ERZ.
