The level of peak ground acceleration (PGA) is denoted in the file name, and so is the type of motion recorded (“Accel” stands for acceleration, “Displ” for displacement).
The first column in the file indicates the time label (in second) with a time interval of 1/256 second; the second and third columns are the recorded motion along the N-S and the E-W directions, respectively. These two directions are graphically indicated in Figure 13 in the competition rules document. In the files, accelerations are measured in g, and displacements in mm.

不論是位移歷時或加速度歷時，第一欄為時間，第二欄為規則所訂振動台NS向歷時記錄，第三欄為規則所訂振動台EW向歷時記錄，時距皆為1/256，在此所謂的NS向與EW向是以規則文件中圖13所示之振動台方位為準。
檔名中有表示此一檔案內容所包含的歷時資料所對應的尖峰地表加速度(PGA)的大小，以及此一歷時記錄的種類(Accel代表加速度，而Disp代表位移)
