Kīlauea’s Lava Overflows Trigger Eruptive Episode 36
Recent observations at Kīlauea Volcano in Hawaiʻi indicate that Eruptive Episode 36 is imminent, as the north vent in the summit caldera continues to exhibit frequent lava overflows. This activity suggests a heightened state of readiness for a new phase of eruptions.
Kīlauea’s Eruptive Episode 36
The Hawaiian Volcano Observatory (HVO) reported that the inflation rates at the volcano have been measured at approximately 0.9 microradian over the past 24 hours. This is an increase from the previous day’s rate of 0.5 microradian. This inflation follows a minor summit inflation period and represents consistent geological activity.
Current Activity Indicators
- Lava Overflows: Frequent lava overflows at the north vent.
- Tilt Measurements: 0.9 microradian of inflationary tilt recorded.
- Estimated Eruption Dates: Episode 36 is likely to begin between November 4 and November 8, with November 5-7 being the most probable window.
- Historical Context: This current eruption behavior is reminiscent of the episodic lava fountains observed during the 1983-86 Puʻuʻōʻō eruption.
Additionally, tremor patterns recorded by the USGS indicate a continuous tremor with sporadic bursts, suggesting that the geological conditions for a substantial eruption are developing. The current lava fountaining episodes are expected to last from several hours to over a week, similar to past events.
Monitoring and Safety Measures
The Hawaiian Volcano Observatory continues to closely monitor Kīlauea’s activity. Coordination is ongoing with Hawaiʻi Volcanoes National Park and the Hawai‘i County Civil Defense Agency to address potential eruptive hazards.
As the situation evolves, scientists are gaining insights that help predict when and how Episode 36 of Kīlauea’s eruptive cycle will commence. With the north vent’s activity and consistent tilt measurements, residents and visitors are urged to stay informed about ongoing developments.
