Abstract
AbstractSurface geology, gravimetric, and heat flow data are used to explain discrepancies between MD site residuals, using the average magnitude site residuals (AMSRj) which are opposite of the station corrections (cStaj) calculated for the 25 selected short-period seismic stations of the Moroccan seismological network. MD site residuals range from −0.29 to +0.32, and appear to be the result of the complex interaction of the predominant near-station geophysical and geological parameters. With this simple qualitative approach, we found that high negative residuals are obtained for older well-consolidated Precambrian crystalline rocks with low surface heat flow, and high positive residuals are attributed to recent unconsolidated sediments with high heat flow. The explanation for the intermediate residual values remains more complex and requires more accuracy and better quality data, and may not be fully justified in this study.
