Formation of the Hawaiian Islands: Volcanic Hotspot and Plate Tectonics Over Millions of Years

The Hawaiian Islands formed as the Pacific Plate moved over a stationary mantle hotspot. Magma rose, creating shield volcanoes that built up into islands. The chain ages from northwest (oldest) to southeast (youngest). All are shield volcanoes with gentle slopes from low‑viscosity lava flows.

Today the islands attract tourists for scenery, climate, and culture, offering hiking, surfing, diving, and more.
