Kīlauea Eruption Update: 2022 Weekly Summary & 2018 Kapoho Flow & Delta

It's been more of the usual from Kīlauea's summit eruption, continuing the pattern of perimeter ooze up lava flows and the small, persistent lava lake. Good viewing also continues from multiple overlooks within Hawaiʻi Volcanoes National Park, evident from webcam time-lapses. There is still no increased volcanic threat to people, but the primary hazard of vog continues to affect the island, more recently the Kona side based on air quality sensors. We review the past week's webcams, images and video illustrating the ongoing changes, as well as monitoring data and reports courtesy of the USGS Hawaiian Volcano Observatory, highlighting the graphics and discussing live viewer questions as we go. Earthquake activity was relatively quiet this past week. This week's USGS Volcano Watch article discusses upcoming volcanoes worldwide, including typical and recent activity. Remembering 2018, we honor Kapoho communities that were over-run 4 years ago this week, including the eruption sequence and public response leading up to the week of greatest devastation. Turning to the science of the area, we examine the findings of the EV Nautilus which surveyed the coastal sea floor to account for how much lava went into the ocean in 2018 (62% of it), and the dynamics of the lava deltas including the patterns of collapses and explosions compared to the Puʻuʻōʻo era. https://www.youtube.com/watch?v=O7f447bekwQ
