Understanding the placement of tectonic plates, marking earthquake prone zones and building earthquake proof buildings is one way of dealing with this problem. An increase of one magnitude step corresponds roughly to an increase of 30 times the amount of energy released as seismic waves. Earthquake studies also help to identify hard and soft soil sites, the rocks beneath the ground and the effects of liquefaction, where the soil responds like water, during an earthquake. Constructing accurate hazard maps is a challenge and remains the focus of much Geoscience research.
