Kīlauea Eruption Update: Lake Crusting & Flow Resumption, November 11, 2021

3:04 AM · Nov 12, 2021

Lava continues flowing from the West Vent within Halemaʻumaʻu crater, though it appeared to slow or stop for several hours earlier in the week before resuming its previous output. During that time, the lava lake surface appeared to crust over and stop moving, but now has reactivated to a lesser degree. The resumption of effusion continues to feed the whole lava lake even beneath its eastern crust, where ooze-up flows along the crater perimeter are now leaking over a larger area of the lowest down-dropped block. The West Vent entry point into the lake also continues to evolve. We present the latest developments on Kīlauea, while also touching briefly on Maunaloa, supported by the latest scientific updates, data and imagery provided courtesy of the USGS Hawaiian Volcano Observatory, as well as our own time-lapse animations produced from their webcams. As usual we mix in a discussion of live viewer questions, including the differences between the 2 recent summit eruptions and the devastation of 2018. The eruption still poses no direct threat to people apart from its gas and particulates, shifting our focus to the observed processes and their context in volcano science. Epic views from the public overlook within Hawaiʻi Volcanoes National Park document the changes, with every visitor experiencing a unique moment in its evolution.
