Maunaloa Deep-dive & Kīlauea Eruption Update, Day 110: April 9, 2021

Little change on Kīlauea's eruption as lava still fills a lake within Halemaʻumaʻu crater, with more time spent on Maunaloa data & research: Latest on Kīlauea: - West Vent entry unchanged from north branch - Lava lake depth slowly deepens, unofficially 226 m / 741 ft - SO2 within recent range, ~850-1000 t/d On Maunaloa: - Recent contraction across summit caldera - Broad inflation in the long-term, recent InSAR - No increased imminence of eruption - Research on the 2002-07 magma surge into both Maunaloa & Kīlauea volcanoes, revealing part of Maunaloa's magma system and a feasible connection between the volcanoes We briefly review monitoring data, time-lapses and photos on Kīlauea's ongoing eruption available courtesy of the USGS Hawaiian Volcano Observatory, before turning to Maunaloa seismicity and monitoring signals. Our deep-dive focuses on research that may give insight into the current patterns on Maunaloa. As usual, we address live viewer questions. https://www.youtube.com/watch?v=a0K1q_3y_sw
