EPICENTER DISTANCE ESTIMATION METHOD USING INCLINATION OF SEISMIC WAVE P WAVE INITIAL MOTION

摘要

PROBLEM TO BE SOLVED: To propose a C value epicenter distance transformation formula according to heterogeneity characteristics in each region to improve accuracy of epicenter distance estimation.SOLUTION: With an epicenter distance estimation method using the inclination of seismic wave P wave initial motion, a relational expression between a C value and an epicenter distance for each region classified by heterogeneity characteristics is obtained, and epicenter distance estimation is improved based on the relational expression.SELECTED DRAWING: Figure 8
