▪ Plates grind against each other ▪ Earthquakes happen along the edges of tectonic plates ▪ The earthquakes happen along fault lines ▪ They are caused by sudden breaking of rock

 ▪ Seismographs  ▪ Seismologists

 ▪ Epicenter  ▪ It is straight above the focus  ▪ It is the location of biggest damage  ▪ Where the earthquakes originates

 The fault on the top side is a normal fault  The fault on the middle is a reverse fault  The fault on the bottom side is a strike slip fault

▪ Continental plates work by grinding against each other ▪ Underground ▪ They create hills and/or slopes

 ▪ S waves caused by breaking  ▪ S waves type: body waves, surface  ▪ Body waves can travel through layers  ▪ Surface waves

 ▪ Body waves: P waves  ▪ Fastest kind of seismic waves  ▪ Travel through rock and fluid
