Kīlauea Volcano: lava Overflow Signals Imminent New Eruption Phase
HAWAIʻI ISLAND – Vigorous lava overflows at the north vent of Kīlauea volcano indicate the next phase of the ongoing eruption is highly likely imminent, according to the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO).Intermittent high dome fountains and bubble-like bursts sending spatter 15-30 feet high have been observed throughout the night,signifying the clearing of degassed lava from the vent.
This activity marks the precursory phase of Episode 33 in the months-long eruption at Kīlauea’s summit. The HVO has revised its projected start window for the new episode to between september 17 and September 20, placing the volcano at a WATCH alert level. While eruptions at Kīlauea typically pose a limited threat to communities due to the confinement of activity within the caldera, ongoing monitoring is crucial as volcanic activity can change rapidly.
Scientists with the HVO noted the vigorous overflows suggest the vent is preparing for a new phase of eruption.”These overflows are vigorous and indicate degassed lava is being cleared from the vent,” they reported. The current activity follows a pattern of cyclic gas piston events, building towards a potential increase in lava flow and fountain heights.
A USGS webcam captured images of the lava overflow on Thursday morning. Residents and visitors are encouraged to stay informed about the volcano’s status through official updates from the HVO and Hawaiʻi County Civil Defense.
