• TSUNAMI HAZARD ASSESSMENT BY TSUNAMI NUMERICAL SIMULATION IN THE SOUTHERN PERU
• CONTENTS
• The tsunami numerical simulation needs a reliable source in order to obtain reliable results, in the present study the sources to be used will be of two kinds: Historical: obtained from records, notes, surveys, etc. of a past event (these events tend to occur in cycle). Future: obtained from studies that try to predict the behavior of natural phenomena.

• From the three modeled scenarios the future event poses the most realistic danger, nevertheless a reoccurrence of the historical sources cannot be discounted. By using recorded data from the (SB RAS) catalog, it was seen that the second source was more accurate, however this second source crosses the Nazca Ridge and historically speaking there are few earthquakes with a rupture that crosses the ridge. The results are consistent with those of Okal et al. (2006), but improving the bathymetry and topography.
• CONCLUSIONS
• To perform the far-filed simulation and compare the computations with recorded values in Hawaii, New Zealand and other locations around the world. Extend the simulation to Vila Vila, Boca del Rio and Arica would help to enhance this study by allowing a comparison not only of tsunami heights, but also flow velocities obtained through sedimentology studies. The overall goal of this study is to improve this contingency plan of Moquegua region with the results obtained from numerical simulation.
