The Republic of Peru is located on the west side of the South American continent, facing the Pacific Ocean, and is known for its famous tourist attractions such as the Machu Picchu ruins and the Nazca Lines. The country is also known to be at high risk of tsunami disasters due to its location in the Circum-Pan-Pacific Earthquake Belt, a region that has experienced major earthquakes in the past. Studies have shown that the number of disasters caused by natural phenomena has been increasing over the past 30 years, and the observation of earthquakes and earthquake-induced tsunamis, as well as the strengthening of forecasting and warning systems for residents, have become urgent issues. Meanwhile, Japan also experienced the Great East Japan Earthquake on March 11, 2011. One of the lessons learned is that tsunami warnings play an important role in facilitating evacuation and preventing accidents on public transport. The Japan Meteorological Agency has set up a study group of experts to further improve the tsunami warning system. Under these circumstances, the Government of Japan conducted a survey of Asian and Pacific Rim countries that are considered to be at high risk from earthquakes and tsunamis in order to grasp the current status of their disaster prevention measures, and decided to support six countries including Peru. The purpose of this Project is to establish an Emergency Warning Broadcast System and a tidal gauge on the Pacific coast of Peru, to improve the country's tsunami disaster-prevention capacity and provide early warnings and to reduce the damage caused by natural disasters.
