Exam-focused facts from the 9 December 2025 current affairs briefing.

Key facts

  • Fresh lava fountains erupted from Hawaii’s Kilauea volcano on Saturday, US vulcanologists said.
  • Sustained lava fountains approximately 50–100 feet (15–30 meters) in height are currently erupting from the north vent.
  • All the eruptive activity is confined to Halema‘uma‘u crater within the Hawaii Volcanoes National Park.
  • Authorities are monitoring elevated volcanic gas levels and the potential spread of “Pele’s hair,” strands of volcanic glass often produced by lava fountaining activity.
  • Hot, glassy volcanic fragments can fall on the ground within 1–2 miles (1–3 kilometers) of the eruptive vents.
