Kīlauea Eruption Update + “Hot Spot” Science, Day 52: February 10, 2021

4:18 AM · Feb 11, 2021

A smaller deflation-inflation (DI) cycle marks the first half of the week on Kīlauea volcano, following on the heels of a larger cycle last week. Lava continues to erupt into Halemaʻumaʻu crater: New: - Lava depth slightly decreases to 214 m / 702 ft - Shorter DI signal already shows rising tilt - Only ~1 day of deflation this cycle vs 4 days last week - Deep dive on the Hawaiian “hot spot” For the current eruption, we review publicly available USGS Hawaiian Volcano Observatory data streams & imagery from while providing geologic context and annotation. In our in-depth segment, we review recent and traditional science on the Hawaiian mantle plume, a.k.a. the “hot spot”, where it comes from, why it's under Hawaiʻi, how it connects to plate tectonics and the creation of the Hawaiian-Emperor Archipelago. As usual, we also take live viewer questions during the update.

As usual, we also take live viewer questions during the update. https://youtu.be/5lQ06kRTl88
