Asking the question because:
I derived cumulative frequency of LPI values for two surface geology units and both for magnitude 7 and 9. But the area of surface manifestation of one unit is anomalous as it shows 80% for Mw= 9 while even don't cross the triggering line for Mw=7!!!
LPI shouldn't be related to earthquake magnitude change. It is more related to water content, presence of sand, and recent sediments. Liquefaction is connected to the geotechnical characteristics of surface layer up to 30 m. If all conditions for Liquefaction phenomena are available then Liquefaction will occur whatever is the magnitude of earthquake is.
regards
Thanks, but we cannot avoid the effect of earthquake magnitude on LPI according to the current calibration procedure (of Iwasaki et al, 1978, 1982) Sir Raed Ahmad. If you have any better idea please share with me.

Dear Atikul,
I just think, if you would like to study LPI independently to earthquake magnitude and compare your results with magnitude dependent. Try to answer the following question will liquefaction phenomena occur when weak earthquake struck the area which is vulnerable to liquefaction?
What is the effect of long duration of vibration despite it is very low magnitude?
Ideas matter!!!
regards
Thanks dear Raed Ahmed. I think all of them are potential variables for liquefaction phenomenon. But the point I made is that it seems that LPI values increase with increasing the magnitude during calibration.
