展示 HN:在地球板块构造的过去与未来地球仪上看当今城市
Show HN: Today's cities on a globe of Earth's tectonic past and future

**Tectonic Globe** 是一个交互式网页项目,旨在可视化地球大陆在 12.5 亿年间的演变过程。该工具采用了 Merdith 2021 板块重构模型,用户可以通过旋转 3D 地球仪,查看当前国家和主要城市在遥远过去的位置,或预测未来 2.5 亿年内它们可能发生的变化。 该项目利用 *pyGPlates* 将现代地理边界映射到板块之上,从而精确计算出历史位置。虽然过去的重构基于科学数据,但对未来的预测仅作为一种交互式推演,而非精确的地质预报。红色高亮部分表示在重构过程中板块碎片发生重叠的区域。

Tectonic Globe

A rotatable Earth that drags today's countries and major cities through the Merdith 2021 plate reconstruction model, plus a simple future extrapolation. Continents keep their color families while the land follows plate motion from 1000 million years ago to 250 million years ahead.
Modern Earth 0 Ma

Today's countries and cities are used as colored crust markers. Country polygons are split by the present-day static polygons from the Merdith 2021 plate model, then each country-on-plate fragment is reconstructed backward with pyGPlates finite rotations. The future side is a constant-motion extrapolation from young plate rotations with a few coarse collision handoffs, so treat it as an interactive sketch rather than a forecast. Red areas mark plate fragments that still overlap after reconstruction.
