Project

I am using the passive seismic microtremor method in geophysics to study the wave resonance pattern in the Tamar rift valley in Launceston, Tasmania. This method uses ambient ground vibrations (microtremor) as a source of energy to interpret shear wave velocity to depth profiles at specific sites. Although Launceston is not located in the proximity of an active seismic zone, damage has occurred to buildings in the city due to earthquake activity on faults associated with the Bass Strait. Previous microtremor and gravity surveys have identify the presence of soft sediments of varying thickness over short distance. These soft sediments overlaying strong bedrock are thought to induce a 2D resonance pattern, amplifying the surface motion over parts of the valley. We conjointly use HVSR, FK and SPAC microtremor survey methods to identify and characterize 2D effects in the Tamar valley. Each method gives complementary information about the geological settings of the Tamar valley.
