Hotspot Volcanism

Most volcanoes happen where plates meet, but some come from a "hot spot" deep underground that stays in one place. As the plate moves over the hot spot, it creates a chain of islands, like Hawaii. It's like moving a piece of paper over a steady candle flame.

Even when everything else is moving, there are steady "sources" of power that stay exactly where they are to create something new.

Hotspot Volcanism (Mantle Plumes) provides a "fixed" reference frame for plate motion. Unlike boundary volcanism, hotspots are intraplate phenomena. They create volcanic "age-progressive" chains (like the Hawaiian-Emperor seamount chain), allowing geologists to calculate the absolute velocity and direction of tectonic plates over millions of years. Certain people act as "hotspots" in history — they stay fixed in their truth while the plate of humanity moves over them, creating chains of new ideas and islands of progress.

SOUND: The "hiss" of steam escaping a tea kettle.
