Özet

In this paper, empirical relationships between modified Mercalli intensity (MMI) and recorded peak ground-motion parameters are developed for Turkey. Strong ground motion data from moderate-to-large earthquakes are employed along with the corresponding MMI information inferred from isoseismal maps and earthquake damage reports. Linear least-squares regression technique is used to derive the following simple relationships between MMI and peak ground acceleration (PGA), peak ground velocity (PGV), and pseudospectral acceleration (PSA): MMI = 0.132 + 3.884 x log (PGA), MMI = 2.673 + 4.340 x log(PGV), MMI = -0.247 + 3.404 x log[PSA(0.3 s)], MMI = -0: 934 + 4.119 x log[PSA(1.0 s)], and MMI = -0.313 + 4.453 x log[PSA(2.0 s)].
