In march 1964,Alaska began to shake.There was a great earthquake.It was the biggest earthquake our country ever had.
Stores and houses fell down.One street dropped 30 feet.One island rose33 feet into the air.Parts of the ocean bottom became dry land.People felt the earthquake hundreds of miles away.
Each year there are many earth-quakes.Most of them are small.They happen in diffarent parts of the world.we are not sure what makes them.But if you are near,you can see the earth move.You may see a big crack in ground.Sometimes the land drops on one side of the crak.It goes up on the other sideof the erack.There is a new hill.The old world has a new shape.from the story we can see the bottom of the sea is nealy dry.对还是错the story wants to tell ua how the strongest earthquake happened对还是错
