  • A recent study overviewed the existing research on the Younger Dryas impact hypothesis.
  • The study notes that there is a "synchronicity" of geochemical signals suggesting that fragments of a comet struck Earth approximately 13,000 years ago.
  • Still, further research is needed to illuminate how the alleged impact might have shaped the future of human civilization.

Rumbling: New Zealand supervolcano needs to be monitored

The Taupo volcano was responsible for one of the most violent eruptions on record.

  • The Taupo volcano is a rhyolitic supervolcano, whose caldera is filled by the largest freshwater lake in New Zealand.
  • About 26,500 years ago, the Taupo volcano generated the Ōruanui eruption, one of the most violent on record.
  • A recent study found that the Taupo volcano was likely responsible for increased seismic activity in nearby areas, suggesting the need for increased monitoring.
