印度尼西亚位于欧亚板块、印度板块、澳大利亚板块和太平洋板块的第三次活动板块交汇处。这一条件使印度尼西亚成为一个具有地震活动水平或高地震活动模式的构造活动区。破坏性地震的发生后，地震余震的发生，往往会增加社会的动荡程度。本研究的目的是计算破坏性地震和随后余震的能量，以便将两者释放的能量进行比较。通过获得这些比较，该研究是基于科学研究，可以作为一个参考，在提供信息的发生地震及其余震的可能影响。利用古滕贝格-里希特经验公式计算能量值，并从ISC（国际地震中心）获得了本库鲁、潘岸达兰、锡默卢、西苏门答腊和塔西克马拉亚5次大地震的余震历史资料。大地震后三个月内发生的余震。通过对一次5级大地震余震的能量分析和计算，发现余震能量占余震能量的比例在0.1%~33%之间，具有随机分布的特征。通过对地震余震能量的比较，结果一般为10%，估计具有走滑机制的地震余震总能量小于10%。而有余震的地震具有逆冲机制，总能量超过10%。
Indonesia is located on the third meeting of the active tectonic world plates which are Eurasian Indian - Australia and the Pacific Plate. This condition makes Indonesia as a tectonically active area with seismicity level or pattern of high seismicity. Occurrence of devastating earthquake followed by aftershocks of earthquakes, often increase the level of social unrest. The purpose of this study is calculate the energy of devastating earthquakes and followed by aftershocks, so it can be compared to the amount of energy released by both of them. By obtaining these comparisons, the study is based on scientific studies can be used as a reference in providing information on the possible impact of an occurrence of the earthquake and its aftershocks. Empirical formula of Guttenberg- Richter was used to calculate the energy value, historical data with aftershock earthquakes was obtained from ISC (International Seismological Center) for five major earthquakes are Bengkulu, Pangandaran, Simeulue, West Sumatra, and Tasikmalaya earthquake. Earthquake aftershocks taken within three months after a major earthquake. From analysis and energy calculations of earthquake aftershocks of a major earthquake with a magnitude of five large, energy-earthquake aftershocks ranging from 0.1% to 33%, with a random pattern. By comparing the energy aftershocks of earthquakes, the results are generally 10%, it is estimated that the earthquake with strike-slip mechanism having earthquake aftershocks with a total energy is less than 10%. While earthquakes with earthquake aftershocks have thrust mechanism with a total energy of more than 10%.
