The above map shows the simple zones where the earthquakes are likely to occur in the United States. This map is a simple map that is drawn based on the fault lines in the areas. The areas are marked likely to have an earthquake based on the fault lines. This is the only variable that is used in the construction of the map. The map that is shown above is an example of a simple map that is drawn based on the fault lines in the area. Based on that data, the expectation of the possibility of the earthquakes is derived. The probability of an area to have a higher earthquake does not mean that there will be an earthquake at that possible line. This cannot be predicted only from the variable that is in contention. The past historic precedent and the physical terrain of the land all play an important role in the derivation of the map. These help in the determination of the probability for an event to occur in a particular place. The world is continually changing based on activities of humans and the earth movements. Based on these the different kinds of activities, the landslide risk maps are drawn. This is used to explain to the people the possibility of the likelihood for an event to occur in a place (Catani, et al., 2005). The possibility of the landslide inventory map has been explored in the following section. These have been explained in the following.
