Significance of joint research between Peru and Japan
Both countries are located in a similar seismic environment,
frequently hit by damaging earthquakes & tsunamis.
Japanese experiences can contribute to disaster mitigation in PeruMerits to Japanese geoscience since subduction-zone EQs arerare events
Tsunamis caused by earthquakes in South America hit Japan(1960, 2010 Chile EQs) and vice verse (2011 Tohoku EQ). Thus
the joint-research contributes to tele-tsunami study in the world.
Promotion of disaster mitigation and capacity building throughsharing the knowledge from the international joint research
