The Hawaiian–Emperor Chain, Mapped Across the Pacific
An interactive geological map tracing every volcano built by the Hawaii hotspot over an 85-million-year, 6,000-kilometre trail.
Field notes
The map combines an interactive point layer with explanatory text about hotspot migration, plate motion, and the 47-million-year bend separating the Emperor and Hawaiian chains. It distinguishes approximate summit positions from island outlines and identifies specific cartographic compromises, including a computed Papahānaumokuākea boundary and a state overlay that rings islands rather than representing Hawaiʻi’s three-nautical-mile marine limit. Coastlines increase from 1:110m to 1:10m detail as the viewer zooms.
