2INTRODUCTION
A new international research program named “Science and Technology Research Partnership for SustainableDevelopment (SATREPS)” has started since 2008 under the joint sponsorship of Japan Science andTechnology Agency (JST) and Japan International Cooperation Agency (JICA).
Our proposal“Enhancement of Earthquake and Tsunami Disaster Mitigation Technology in Peru” was selected as one ofthe projects in the field of natural disaster prevention in April 2009. The Record of Discussion (R/D) wassigned on 15 January 2010 by JICA and National University of Engineering (UNI) in Lima, Peru. This
paper describes the overall objectives and research plan of the project.
BACKGROUND AND OBJECTIVES OF THE PROJECT
Peru is located in the circum-Pacific seismic belt with high seismic and tsunami risks. It is understood thatboth Peru and Japan are located in a similar seismic environment and are frequently hit by damaging
earthquakes and tsunamis. In this region, large plate-boundary earthquakes occurred recently in theoffshore of Atico (M w =8.4, 23 June 2001) and in the offshore of Pisco (M w =8.0, 15 August 2007). A largenumber of buildings and infrastructures were collapsed, hundreds of people were killed, and tsunamis werealso generated by these events. Thus, earthquake and tsunami disaster mitigation draws considerable
attention in Peru.
RESEARCH PLAN AND ORGANIZATIONAL STRUCTURE
In this research project, a comprehensive research towards earthquake and tsunami disaster mitigation inPeru will be carried out under strong collaboration among researchers of Peru and Japan. Fig. 1 shows theorganizational structure of this five year projects. The joint research will be carried out in five mainresearch topics: G1) Strong motion prediction and development of seismic microzonation; G2) Developmentof tsunami countermeasures based on numerical simulations; G3) Enhancement of seismic resistance ofbuildings based on structural experiments and field investigation; G4) Development of spatial information
database using remote sensing technology and earthquake damage assessment for scenario earthquakes; G5)
Development of earthquake and tsunami disaster mitigation plan and its implementation to the society.
Fig. 2 shows the research topics and items of the project. Based on the research outputs from the fourgroups (G1-G4), the disaster mitigation plan group (G5) will propose and implement earthquake and tsunami
disaster mitigation plans to case study areas in Peru. Three case study areas will be decided soon after
preliminary surveys. A part of Metropolitan Lima including Callao has already selected as one of the study
areas. The other two areas are still in discussion. Other than these areas, the affected areas due to therecent earthquakes, Pisco (the 2007 event) and Camana, Arequipa etc. (the 2001 event), will also be
considered in developing hazard and damage assessment models.
RESEARCH AGENDA OF G1 GROUP
The seismic motion and geotechnical group (G1) is responsible for constructing fault models for large
scenario earthquakes along the subducting plate and deep and shallow soil models to come up withmicrozonation maps. In order to construct the fault model, surveys of historical seismic activities will beconducted and strong motion observations will be carried out by installing seismometers in a number of1222

locations (see Fig. 4). For the construction of deep and shallow soil models, the group will conductgeophysical and geotechnical surveys including borehole and PS loggings as well as surface wave andmicrotremor measurements. The analysis of earthquake data from small events will also be carried out.
The agenda for constructing the microzonation maps includes strong motion simulation based on the faultmodels and the deep/shallow soil models, estimation of amplification due to surface soils and estimation ofslope failure.
IMPLEMENTATION AND PROSPECTED OUTPUTS OF THE PROJECTThe Japanese Detailed Planning Survey Team organized by JICA visited Peru from August 5 to 13, 2009 hada series of discussions with the Peruvian organizations led by CISMID/UNI. The team and the Peruvian
organizations agreed on the matters referred to in the document (JICA, 2009).
The agreement is that the objective of this project is to develop technologies and measures for assessmentand mitigation of earthquake/tsunami disasters caused by large-magnitude inter-plate earthquakes occurring
off the coast of Peru. It is further envisaged that such technologies should be widely used in Peru, and also
disseminated and applied to pacific-rim countries, especially to neighboring countries, facing the risks oflarge-magnitude inter-plate earthquakes and tsunamis. In addition, the project is expected to contribute to
the enhancement of capacity as well as the advance of research for both Peruvian and Japanese research
institutes involved in this project.
The progress of the project will be presented in the near future.
