Megathrust earthquake

Earth can do amazing things, like making big earthquakes called megathrust earthquakes. These happen when pieces of the Earth’s crust, called tectonic plates, push against each other. One plate moves under another, and this can build up a lot of pressure. When the pressure finally lets go, a big earthquake happens.

Megathrust earthquakes often happen under the ocean, near special places called oceanic trenches. These earthquakes can move the sea floor a lot. This movement can create big waves called tsunamis that travel across the water.

These earthquakes are some of the strongest we know. They can be very powerful and last for several minutes. It’s important for people to learn about them so we can stay safe. Places like the Pacific Ring of Fire see these kinds of earthquakes sometimes.
