Mokuʻāweoweo is the summit caldera of Mauna Loa—and the heart of the 2022 eruption. What the name means In Hawaiian, Mokuʻāweoweo roughly translates to “island of glowing fire” or “place of fiery red reflections.” Super fitting. It started at Mokuʻāweoweo (summit fissures, glowing caldera) Then within hours, magma drained sideways into the Northeast Rift Zone That rapid migration is hard to catch so clearly — and 2022 gave a front-row seat. 2. Fissures behaved like living things Long cracks opened, closed, re-opened Lava fountains lined up, then narrowed to a few vents You could literally watch pressure shifting underground 3. The speed was wild Lava raced downslope toward Saddle Road It moved fast enough to threaten infrastructure but slowed just in time That balance between “uh-oh” and “okay we’re good” was razor thin. 4. The monitoring worked Seismic swarms, inflation, gas — all the warning signs lined up Forecasts were accurate enough to keep people safe It was a huge validation of modern volcano science.
