(a) Peak Ground Accelerations (PGA) of fore-, main-, and after-shocks as a function of time for the four events. The values of the PGA are measured at the DGY, TEJ, ADO and HUK stations for the 2007, 2008, 2009 and 2011 events, respectively. Time 0 indicates the origin time. The broken horizontal lines on each graph indicate the relative values of PGA corresponding to ML 2.0. Considering events larger than ML 2.0, three inland earthquakes on the Korean Peninsula have very few aftershocks within several hours, while aftershocks of the 2011 Yellow Sea event continued for at least 5 days. (b) Locations of the four events and stations used to compare the aftershock activity.
