Hapcheon: impact traces beneath a basin

Shock → deposition and landscape change → evidence today · explanatory steps

An explanatory illustration of the present Hapcheon basin and underlying rock, not an aerial photograph, measured borehole section or impact reconstruction.

Shock deformation in drill cores confirms an impact origin at the Jeokjung–Chogye Basin in present-day Hapcheon, South Korea. The low basin also records later sediment accumulation and landscape change.
