Kīlauea Eruption Update, Day 93: March 23, 2021

3:17 AM · Mar 24, 2021

Kīlauea's summit eruption continues uninterrupted for over 3 months now, with little change as lava now flows through two submerged entries from its West Vent into Halemaʻumaʻu crater, adding to the still-deepening lava lake: New on Kīlauea: - Steady, unchanged double entry from West Vent, active lava footprint stable - Lava lake depth creeps up to 223 m / 732 ft; total of 3 m / 20 ft in 2 weeks, or 7 m / 20 ft in 1 month - No new DI cycle in past half-week, aids stability - SO2 output still variable, up slightly to 950-1100 t/d - Upper East Rift refilling “at rates similar to before the December 2020 eruption” Today's coverage steps back to examine the sum of the slow changes over the past month on Kīlauea's summit and flanks, using monitoring data, graphs, updates and time-lapse animations from the USGS Hawaiian Volcano Observatory.
