How geology built civilisation | with Anjana Khatwa | Part 2

Did ancient Hawaiians map their volcanic islands through mythology — centuries before geologists figured out hotspot volcanism? Earth scientist Anjana Khatwa makes the case. ▶ Missed Part 1? Watch it here: https://youtu.be/LpuMY_zTmCE Filmed at the Ri on 26th April 2026.
