Document Summary
They travel very fast and efficiently through solids. When broken it releases a lot of energy. Shock waves move from all directions at the same time. The deformation that an object undergoes in response to stress (equal force per unit area) The strain energy is the energy being stored or accumulated. If there is lots of energy can cause lots of damage. Tensional stress (divergent boundaries) like mid ocean ridge or transform boundaries. (moving side by side) Compression stress in the crust (where you have mountains being built) (convergent boundary) Earthquakes can happen at any type of boundary. It"s the point on the surface above where the rocks break. The deeper the rock break the lower the damage because of the waves that are caused travel further and become weaker. If it"s shallow, the damage will be greater. Finding the focus is more involved because more calculations than epicentre. They are all created and move at the same time.
