Did You Know?
Earthquakes can shake the ground a lot!
Close to the Quake
If you are close, it shakes hard.
Far from the Quake
If you are far, it shakes less.
What epicentral distance Does
It helps us know how strong the shake is.
It shows how far the quake is from us.
It helps keep people safe from big shakes.
It tells us where to look for damage.
It helps scientists learn about quakes.
It is used to make maps of quakes.
More About epicentral distance
Long ago, people felt quakes but did not know why. They made tools to feel the shakes. Now, we can see where the shake starts. This helps us learn more about quakes.
When a quake happens, we can see how far it is. This helps us know if we need to be safe. It helps keep people safe in big cities.
In the future, we will learn even more. We might find new ways to feel quakes. This can help us be ready and safe!
