Yesterday  there  was  no school  .because that night  there was a big  earthquake. My grandma  and grandpa  in  Chirstchurch  had  to evacuate there house .  Because  they  were  very  close to the sea. So they move on to the hill .  And stay until  it was morning. And went back  to there house . Earthquakes can sometimes be very dangerous. Sometime they wreck the roads. And wreck houses and some people can die in earthquakes . They are very dangerous
