     Some things happen that we can not stop. We can not stop the power of the nature. For example, a
flood comes when there is too much water on the land. Sometimes, it can come after a big storm when
too much rain falls on the land. Sometimes, it can come after a big rainstorm out at sea where too much
sea water comes onto the land. Fast moving flood water can hurt us. They can also hurt our homes. We
cannot stop a flood from coming, but we can try to stop the water from coming into our homes. We can
try to stop the water by making a  wall  with  sandbags. Sometimes, the  sandbags  help stop the water.
Sometimes, they don't.
     An earthquake happens where the land moves. The land goes up and down and all around. The land
shakes. We can get hurt by things that  fall  down in an earthquake. Falling things can start fires. We can
not stop an earthquake  from coming. We  can  try  to  make  our  houses strong so that they will not fall
down in an earthquake.
