An earthquake hazard map provides, at any location, the value of a ground motion intensity measure (for example, horizontal peak ground acceleration, PGA) that is expected to be exceeded at least once in 100 year mean return period. The earthquake hazard maps are developed by determining the simulated ground motion intensities at every gridded location for 10,000 realizations of next-year activity of earthquake events. At each grid location, the intensities are ranked and the ground motion intensity of the mean return period of interest is recorded.
Nauru faces many economic and environmental challenges. In the 1970s the country experienced an economic boom due to phosphate mining, however, because of mismanagement of the revenue, the country currently has limited financial resources to undertake many of its development programmes including environmentally sound waste management. In the face of a range of environmental, social and economic threats from poor waste management and pollution, and in the context of the limited resources, this National Solid Waste Management Strategy is developed as a matter of priority.
