Kīlauea Eruption & Maunaloa Update, Day 89: March 19, 2021

One day shy of the 3-month milestone, Kīlauea's summit eruption continues as lava flows from its West Vent through two submerged entries into the still-filling lava lake within Halemaʻumaʻu crater: New on Kīlauea: - Double West Vent entry stabilizes, continues - Lava lake depth unchanged at 222 m / 728 ft - Most recent DI cycle completes - SO2 output slowly trending down, last measurements 650-700 t/d On Maunaloa: - Small earthquake cluster in upper Kaʻōiki fault zone, no change to eruption potential - Review of selected USGS graphics about earthquake rates We begin with a review of new imagery published by the USGS Hawaiian Volcano Observatory, time-lapse compilations from USGS-HVO webcams, and public data monitoring streams of current activity on both volcanoes, summarizing geologic changes and adding context, commentary and annotation. Today we spend a little more time reviewing earthquakes and seismic techniques. https://www.youtube.com/watch?v=izw6hPcJ2VE
