چکیده
In recent years, the development of seismic networks in Metropolitan Lima, administrated by public and private institutions, has received special attention since it makes possible quantification different indexes under occurrence earthquakes. Therefore, integration information both from acceleration sensors site conditions microzoning studies allows estimation extent damage quasi-real time. this study, implementation a system to evaluate parameters uniform grid 250 x m2 resolution is reported. regard, peak ground (PGA) values available time-history records are computed reduced engineering bedrock level. Then, means interpolation technique called Ordinary Kriging, which each station considered as random variable correlation between pair such variables depends only on distance their coordinates, distribution evaluated. Amplification factors applied order finally bring PGA up surface A quantitative evaluation accuracy our results performed using two earthquakes with moment magnitude larger than 5: 2019 Mw 8.0 Lagunas earthquake 2021 6.0 Mala earthquake. The have reproduced some response diverse geomorphological deposits Lima suggest inclusion number strong motion stations reduce errors.
