Have you ever wondered what an earthquake sounds like?
Scientists measure earthquakes using seismometers.
The higher the reading on the seismometer, the more powerful the
Japan's 2011 earthquake was very powerful. Scientists have
turned their measurements from seismometers into sounds that we can
hear. Have a listen:
The loud noise at the beginning is the main earthquake. Can you
hear popping sounds after the first noise? They are aftershocks.
This is where the earth is still moving slightly. These aftershocks
can last for years after a large earthquake.
