Abstract
New empirical relations between macroseismic intensity and ground motion parameters including peak ground acceleration and velocity are developed using strong ground motion data and Modified Mercalli Intensity (MMI) information from earthquakes within Iran plateau. The strong motion data consists of 116 three-component waveforms of 23 earthquakes with Mw 5.1–7.3 occurred from 1977 to 2017. The intensity values for each ground motion record were assigned considering the location of accelerograph stations on the isoseismal maps. Simple predictive equations are obtained by fitting a linear model to the mean peak ground motion values applying least squares regression. However, visual inspection of residuals shows magnitude and distance dependency for this set of equations. Improved relationships between ground motion and intensity are derived by comprising magnitude and distance terms as predictive variables. The refined ground motion to intensity conversion equations show smaller variability than simple linear equations in predicting MMI values. Both proposed models are compared with similar relationships in Iran and other regions of the world. The observed discrepancies in relationships may reflect the differences in input data, especially the macroseismic intensity assignments as well as regional variability. The proposed relations can be used for rapid hazard assessments and loss estimation in Iran and surrounding regions.
