USArray
Usarray is like a big microphone that listens to the ground all around the United States. It listens to see if there are any tiny movements or vibrations happening deep underground, or if there are any sounds that we can't hear, like earthquakes.
It's made up of lots of different sensors, which are like ears, that are placed all around the country. These sensors are special because they can hear really well even when things are moving just a tiny bit.
When the sensors pick up some movement or sound, they send a message to a big computer so that scientists can study it and try to figure out what's happening underground. This helps us learn more about how the Earth is made and what's going on deep down inside it.
