Kīlauea Eruption Update: Viewing, Vog, & 2018 Week 3

3:05 AM · May 20, 2022

Kīlauea's steady pattern continues, with active lava in its small, persistent lava lake and numerous large lava flows that ooze up periodically through the hardened crater floor near its perimeter. Reliable viewing also persisted this past week from multiple overlooks within Hawaiʻi Volcanoes National Park, continuing a long period of no increased volcanic threat to people. However, variable winds over the past few days have brought gas emissions back into public areas of the park and surrounding communities, so we spend extra time discussing the vog, which remains the primary hazard of concern for this eruption. We review the past week's time-lapse, images and video illustrating the ongoing changes, using webcams, monitoring data and reports courtesy of the USGS Hawaiian Volcano Observatory, highlighting the graphics and discussing live viewer questions as we go. As usual, we also touch on earthquakes as well as Maunaloa, including this week's USGS Volcano Watch article on its 1916 eruption. Remembering 2018, we discuss gas emissions and weather effects during that eruption, always keeping in mind those impacted by those events. We replay several videos from the eruption's third week, including updates by Ikaika Marzo and his first 15-minute interview with Philip, which we reflect on after 4 years of ongoing work, along with early predictions of how the eruption would unfold. 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.
