Kīlauea Eruption Update, Day 75: March 5, 2021

Still only minor changes in Kīlauea's eruption within Halemaʻumaʻu crater in the short-term, but we also review longer-term changes: New: - Active lava contracting into more oval shape - Quick restart of pressure cycle drop, 4 days since previous - West vent flows continuous into lake, pulses flows from upper N part of cone - Highest recorded lava depth beneath West Vent of 220 m / 722 ft - SO2 emissions fluctuating ~1000 t/d As usual, we review publicly available monitoring signals and imagery provided by USGS Hawaiian Volcano Observatory, as well as their webcam images which we also use to produce our own time-lapse sequences. We narrate the geologic features while highlighting them on-screen, briefly check in on neighboring Maunaloa volcano, and address several viewer questions in our end-of-week update. https://youtu.be/dK3t5wo0XeA
