I want to estimate the approximate PGA time for far-field earthquake records.
Is there any paper you can introduce to me for this or some kind of intensity function or some kind of a function for converting stationary to non-stationary series?
Dear Amir, Does the method you mentioned estimate PGA occurrence time from first of acceleration record in a specified station or just estimate the PGA occurrence from the time that earthquake begins or the time of starting acceleration record from the time earthquake begins?
