Abstract
At first, the characteristics of two maximum acceleration estimation formulas by Cornell and Si-Midorikawa were studied. It was found that Cornell formula overestimates the maximum acceleration at the short distance from the earthquake fault than that by Si-Midorikawa. Secondarily, the collapsed land volume was compared with the maximum accelerations estimated from the both formulas. The correlation between collapsed land volume and maximum acceleration by Si-Midorikawa formula was better than that by Cornell formula, although the correlation was poor. Furthermore, It was confirmed that the Si-Midorikawa formula is more applicable than Cornell one, through a case study on Shikoku for the coming Tonankai-Nankai Earthquake. Eventually, Si-Midorikawa formula seems more advantageous than Cornell one for the rational explanation on the collapsed land volume with the maximum acceleration with distance attenuation.
