I am unsure of EXACTLY what a micro-tremor is even after reading the abstracts. I can tell you that luminescence dating has been used for roughly 40 years to date the movement of faults using the "collevial wedge". You have an expert on this with a fellow countryman, Morteza Fattahi. You should get in touch with him. I also have a paper on my research gate site that might help " GUIDE TO LUMINESCENCE DATING TECHNIQUES AND THEIR APPLICATION FOR PALEOSEISMIC RESEARCH".
