seismic reccurency parameters
seismic reccurency parameters
i have to find the recurrency parameters used in the gumbel type iii (maximum likelihood-weibull) methodology for a catalog of earthquakes (needed for a seismic hazard analysis). now, from what i understand the parameters are: w,m,u and lambda. and i have to find p(m)=exp[-((w-m)/(w-u))^1/lamda]. w-maximum magnitude; u-the extreme value associated to the unit of time (????) lambda-is giving the asimptotic curve to the superior part of the anual probability; p-the probility of not obtaining bigger magnitudes than m. who is u? how do i find lambda? posting in the eng-tips forums is a member-only feature. |
