hypocentre/focus | The hypocentre and the focus are the same thing and they sit under the epicentre |
core | The core sits under the ground and is really hot that you will die if you go to the core |
crust | The crust is what we walk on and it is 70% H20 ( water ) |
mantle | The mantle is below the crust and is made of sylican and oxygen |
Indo-Australian plate | This is one of the tectonic plates |

richter scale | The richter scale measures how powerful the energy is in a earthquake |
mercalli scale | The mercalli scale is used to measure how much damage there is in a earthquake |
molten | Molten is larva that is realy hot and it can burn everything |
liquefaction | Liquefaction is water sitting in sand and when there is no room for the water the water goes to the top and makes big puddles |
tsunami | A tsumani is a wave that can race at powerful seeg and strength |
liquefaction | liquefaction is when the groung gets really liquidly and can destroy things |
primary waves | Primary waves can go through solids, liquids and gases |
primary effects | Caused by the earthquakes |
secondary effects | A result of the primary effects |
shearing | Shearing is where the tectonic plates rub againest each other |
compression | Compression is where the tectonic plates push againest each other |
landslides | landslides are when the soil and rock get loose and come toppling down when a earthquake comes |
