Volcanoes Or Earthquakes

I believe that earthquakes are the most dangerous out of the two because earthquakes can make buildings fall while if your smart, you would get away from a volcano as soon as it show any signs of explosion.

How Far Down is the Center of the Earth?

1. The deepest mine in the world is in South Africa and is 3.6 km deep.
2. You would have to dig about 3000 km to reach the mantle.
3. If me and my homies were to dig a whole in my backyard, once we got there we would see red and orange magma which would burn anything it touchs. Then when I got home my mom would beat me.
