Lava continues to cool at Kīlauea summit following short-lived eruption

Overnight webcam views of the Kīlauea summit showed sparse incandescent spots as lava continues to cool just outside Halemaʻumaʻu crater following the eruption that started Sept. 10 and ended Sept. 16.

According to Hawaiian Volcano Observatory, it is unlikely that the recent eruption will resume based on the behavior of past, short-lived summit fissure eruptions at Kīlauea summit in 1982, 1975, 1974, and 1971, which all ended abruptly.

No unusual activity has been noted along the East Rift Zone or Southwest Rift Zone; steady rates of ground deformation and seismicity continue along both. Measurements from continuous gas monitoring stations on the middle East Rift Zone remain below detection limits for sulfur dioxide.

Summit seismicity has remained low, with very few earthquakes over the past week, and tremor is at background levels. Summit tiltmeters recorded net inflation over the past week.

Hawaiian Volcano Observatory continues to monitor activity.
