Kīlauea Eruption Update: Vent & Perimeter Flows

3:05 AM · Apr 22, 2022

Kīlauea's eruption within Halemaʻumaʻu has been sprawling with lava flows that emerge through the hardened crater floor near its outer margins. Infrequent lulls, including a 2-day event ending today, have reduced these perimeter breakouts while maintaining active lava at a lower level within the persistent summit lake. Last week's breakout from the West Vent complex continued in the early part of this week, matching the pattern of the perimeter “ooze-up” flows. This remains a great time for public viewing, continuing a long period of no increased volcanic threat to people. We share video and a series of time-lapse animations illustrating these views and changes, along with USGS Hawaiian Volcano Observatory webcams, monitoring data and reports, annotating the graphics with an on-screen pen. As usual, we also discuss live viewer questions. This program is brought to you in part by a grant from the Hawaiʻi Island Strong Fund of the Hawaiʻi Community Foundation in partnership with the County of Hawaiʻi, and from donations from viewers like you.
