Kīlauea & Maunaloa Update, June 10, 2021

3:15 AM · Jun 11, 2021

Both volcanoes are quiet on their surface, but Kīlauea especially is showing signs of life underground with increasing earthquakes and ground tilt. We examine the current imagery, monitoring signals and webcams, including a new view of Maunaloa from Maunakea, courtesy of the USGS Hawaiian Volcano Observatory, and evidence of subsidence of the hardened lava lake surface. After our review of the 2020-21 Halemaʻumaʻu activity, we turn to a recap of recent research on the 2018 eruption, focusing in detail on the lava delta of Kapoho in comparison to lava deltas of the Puʻuʻōʻō era. We discuss live viewer questions as usual at several points in our presentation. 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 smaller donations from viewers like you.
