Calculation method of time history including large-scale earthquake and its aftershock

The 2011 earthquake off the Pacific coast of Tohoku, which saw many aftershocks after the main shock, demonstrated the need to assess seismic stability of railway facilities against large earthquakes and aftershocks. Because the ability to predict aftershocks is necessary, the authors propose a method that draws on statistical processing of past earthquakes to calculate the magnitude and time lapse between a main shock and its aftershocks. Time history was calculated for a main shock of magnitude 7.0 and its aftershocks, and the impact of the aftershock on the damage to the structures was also examined.
