The destructive earthquakes occurred in Sumatra are dominated by medium earthquakes, which generally come from the Sumatra fault and to have a direct impact on the land, buildings and around residential buildings. These earthquakes can be classified into high-frequency earthquakes with low-vibration periods. The hazards caused by the earthquake are mostly from damage and collapse of the residential buildings. This study is a literature review that aimed to observe the characteristics of rocks and ground in Sumatra areas based on b-value that obtained using seismicity estimation is related to the resistance of the earthquake on residential buildings. The b-values obtained from some previous researches so that they could be concluded, and then analyzed the type and condition of the local ground and then evaluated its effect on the surrounding buildings. Based on the outcomes, the estimation of b-value seismic parameters in Sumatra was found 0.34 to 0.5. It means that the type of ground in areas of Sumatra has a hard rock layer. Physically, it has highfrequency earthquake waves; low vibration periods, spreading efficiently on hard layer and having a direct impact on local buildings consequently the risk of collapse building will be higher.
