Is a hidden microplate causing thousands of earthquakes in Alaska?

Alaska is having lots of earthquakes because there’s a tiny hidden piece of Earth moving under it like a puzzle piece shifting in a game.

Imagine you're playing with building blocks. You stack them up, and then one block moves just a little, poof! The whole tower wobbles, and maybe even some blocks fall off. That's kind of what’s happening in Alaska. There’s this hidden microplate, like a tiny block under the ground, that's moving slowly but steadily. It doesn’t look like much, but it causes hundreds, sometimes thousands, of small earthquakes.

Why we didn't know about it before

It's like having a sneaky little friend who moves your toys while you're not looking. The microplate is so small and deep under the ground that scientists only recently found out about it. They watched how the ground shook in different places and figured out this tiny piece of Earth was moving around, making all those earthquakes.

Even though it's tiny, its movements are powerful enough to shake Alaska, just like a little push can make a big tower wobble!

Examples

  1. Imagine a tiny piece of land moving under Alaska, causing the ground to shake like when you push your friend on a swing.
  2. It's like a puzzle: if one part moves, others might shift too, creating many small shakes.
  3. Sometimes, this hidden movement can cause big earthquakes that people feel all over Alaska.
