Kīlauea Eruption Update: 2022 Usual Oozes & 2018 Causes

3:20 AM · May 28, 2022

The eruption continues as usual on Kīlauea's summit, with numerous large lava flows that ooze up periodically through the hardened crater floor near its perimeter, and active lava constantly, but slowly circulating in its small, persistent lava lake. Viewing is still reliable from multiple overlooks within Hawaiʻi Volcanoes National Park, continuing a long period of no increased volcanic threat to people, but we follow up on the effects of gas emissions and vog on island communities over the past week, which remains the primary hazard of concern for this eruption. We present the various views and video submitted by Two Pineapples showing recent activity. 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 last week's 4.7 under Hualalai volcano. This week's USGS Volcano Watch article discusses upcoming magnetotelluric (MT) and airborne electromagnetic and magnetic (AEM) mapping, which we expand upon for the benefits of residents who will see the aircraft flying the coming months. Remembering 2018, we briefly discuss the origin of the eruption as evidenced by geophysical and geologic observations, combined with studies of lava chemistry changing as the activity progressed.
