description | This report utilized a method called the Microtremor Survey Method (MSM) to estimate the subsurface soil structure of the major geology formations in Singapore. Microtremors records from 25 locations in Singapore, obtained by seven velocity sensors arranged in an array were used. The data were processed using the Spatial Auto Correlation (SPAC) method and subsequently, the soil structures were derived by inversion. Existing borehole data that are near to the locations of recordings were used as a reference for comparison for both the subsurface soil structure and 𝑉𝑆30 (average shear wave velocity up to 30m) values. 𝑉𝑆30 values were also used to classify the site according to the IBC 2006 Site Classification table. The results obtained from SPAC analysis corroborated with nearby borehole information to a large extent, except for highly variable geology formation such as the Old Alluvium. Overall, this study established the reliability and accuracy of the MSM. |
