Kīlauea & Maunaloa Update, July 15, 2021

Both Hawaiʻi Island volcanoes show interesting patterns due to subsurface movement, with earthquakes ongoing both beneath Maunaloa's flank and under Kīlauea's summit and upper east rift connector, with lesser activity beneath Kīlauea's Upper East Rift Zone and nearby south flank. We review the publicly available monitoring data on both volcanoes courtesy of the USGS Hawaiian Volcano Observatory and highlight the patterns, discuss live viewer questions, and dive into some curiosities of the 1984 Maunaloa eruption as our bonus segment, tagging onto this week's USGS Volcano Watch article. This program is brought to you in part by a grant from the Hawaiʻi Island Strong Fund of the Hawaiʻi Community Foundation in partnership with the County of Hawaiʻi, and from smaller donations from viewers like you. https://youtu.be/46pm0j-pJCg
