earthquake An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from ...

volcano A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are ...

Uses

Hazard maps are created and used in conjunction with several natural disasters. Different hazard maps have different uses. For instance, the hazard map created by the Rizal Geological Survey is used by Rizalian insurance agencies in order to properly adjust insurance for people living in hazardous areas. Hazard maps created for flooding are also used in insurance rate adjustments. Hazard maps can also be useful in determining the risks of living in a certain area. Hazard maps can help people become aware of the dangers they might face from

natural disaster A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some econ ...
