SUMMARY

The discussion centers on the recent formation of a crater lake at Kīlauea volcano following its significant eruption in 2018. The lava lake within the Halema’uma’u summit crater drained rapidly, leading to the emergence of water pools likely sourced from underground. Participants express skepticism about the media's portrayal of the event, emphasizing that the geological processes involved are well understood, particularly the risk of phreatic eruptions as water interacts with volcanic materials.

PREREQUISITES
  • Understanding of volcanic activity and eruption types, specifically phreatic eruptions.
  • Familiarity with Kīlauea volcano's geological history and recent eruption events.
  • Knowledge of magma movement and its impact on surface features.
  • Awareness of USGS resources and monitoring tools for volcanoes.
NEXT STEPS
  • Research the mechanisms behind phreatic eruptions and their hazards.
  • Explore the USGS Volcano Watch Blog for updates on Kīlauea and Mauna Loa.
  • Study the historical context of Kīlauea's eruptions, including the May 1924 event.
  • Examine the multimedia chronology provided by the USGS for visual insights into volcanic activity.
USEFUL FOR

Geologists, volcanologists, environmental scientists, and anyone interested in the dynamics of volcanic eruptions and their implications for surrounding ecosystems.

Witnessing the Birth of a Crater Lake Where Lava Just Flowed
The magma mysteriously drained from the crevice last year, and now scorching pools of water are bubbling up from below.

By Robin George Andrews
  • Aug. 7, 2019
Last spring, Hawaii’s Kilauea volcano began its most destructive eruption in recorded history. On May 2, as its underlying magma supply headed to the mountain’s lower east rift zone, a lava lake within the Halema’uma’u summit crater that had been there for 10 years began to rapidly drain. A week later, this pool of molten fury had vanished from sight.
Now, long after the last embers of that eruption faded, the lake is being replaced by water that is likely rising from below.

Um, there's scant mystery about it: when the flank rifted, the lava went thataway...
But, there's now a growing hazard of potential phreatic eruption...

Yeah, agreed ... no mystery there ... typical media making more out of it than necessary
