Developement of Seismic Hazard Assesment For Sudan
Sudan has a long history of earthquakes. It is known to seismologists as areas of low moderate seismic activity, because it is located within interpolates regions. These interpolate earthquakes can be found on nearly every continent; therefore Sudan is not free from earthquake activities. The seismi...

| Summary: | Sudan has a long history of earthquakes. It is known to seismologists as areas of low moderate seismic activity, because it is located within interpolates regions. These interpolate earthquakes can be found on nearly every continent; therefore Sudan is not free from earthquake activities. The seismic hazard for Sudan, following the deterministic approach is done in this report. The input for computations is represented by source catalogue. Seismic sources are parameterized using the knowledge about past seismicity and from United States Geological Survey (USGS). In this study there are two attenuation equations McGuire, 1976 and K. W. Campbell 2002, 2003 that are used to calculate the peak ground acceleration (PGA). The earthquake with maximum PGA is the maximum credible earthquake. The results shows that the minimum value of PGA is 0.000094 and locate in South-Western Sudan and the maximum value of PGA IS 0.0014 and locate in northern Sudan so large parts of Sudan lies within zone zero according to Uniform Building Code (UBC) where the PGA between 0.0 to 0.05g. Therefore the seismicity of Sudan is low to moderate. Finally, the map of deterministic seismic hazard is drawn using all pervious results |
