dc.description.abstractThe conjunction of seismic records and site effect parameters can lead to the adequate estimation of seismic indexes in urban areas. In this regard, this study uses the map of soil amplification factors obtained in previous studies and the availability of time history waveforms at different locations throughout Metropolitan Lima and Callao to estimate the geospatial distribution of maximum values of horizontal acceleration after the occurrence of earthquakes. Results for three earthquakes of intermediate magnitude and distinct epicenter locations are publicly available in an online system created within the framework of this study (Amaru Peru) and showed that amplified motions could be mainly observed in the lowlands of populated slopes as well as in the eolian sandy deposits.
dc.description.sponsorshipFunding: In the following years, the number of seismic instruments slowly increased. As evidence, only 12 instruments recorded the mainshock of the 2007 Pisco earthquake, 10 of them located in Metropolitan Lima and two in Ica [10]. In order to overcome this situation, scientific and academic institutions have been promoting the importance of the implementation of seismic networks and received financial support from the Peruvian and international governments.; Funding text 2: This study was supported by the Concytec-World Bank research program “Improvement and Extension of the Services of the National System of Science, Technology and Technological Innovation” 8682-PE through its executing unit ProCiencia [contract 038-2019] and by the Science and Technology Research Partnership for Sustainable Development (SATREPS) project on “Development of Integrated Expert System for Estimation and Observation of Damage Level of Infrastructure in Lima Metropolitan Area” under the patronage of the Japan Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). The authors would also like to thank the National Training Service for the Construction Industry (SENCICO) and the National Council of Science, Technology and Technological Innovation (CONCYTEC) for supporting this work [contract 118-2018-FONDECYT]. Finally, we express our gratitude to the assistant researchers in CISMID who helped in the completion of the study.
