Earthquakes destroy many buildings and take lives. One cause of earthquakes is an active fault. The impact of a sudden displacement of the ground shakes the Earth and causes an earthquake. Japan has compiled a database of active faults found to date and is preparing for earthquakes by examining each one in detail to predict its magnitude. Surveys are also being conducted to find new active faults. In this episode, we'll see how one researcher is searching for active faults hidden in the seafloor by using ultrasonic waves sent out from a ship.

The number of foreign visitors to Japan has been on the rise since the COVID travel restrictions have been lifted. However, many are not fully aware of natural disasters that strike Japan such as earthquakes, tsunamis, and typhoons. Now, there are efforts to ensure the safety of visitors during disasters. The newly developed "announcer drone" translates text into 29 languages and instructs people to evacuate while flying. At evacuation centers, local governments are well prepared to notify important information to those who do not understand Japanese, using translation systems developed for emergency situations.

Droughts are increasing due to global warming. The latest simulations predict that megadroughts could occur along the Mediterranean coast and the west coast of the US. Now, Japan's cutting-edge technology is attracting attention as a solution to water scarcity. In Saudi Arabia, there are high hopes for using a filter developed by Shinshu University that removes over 99% of salt content from seawater. Meanwhile, Egypt is looking into a water dispenser developed by a Japanese venture company which produces drinking water from air.

Wildfires are increasing worldwide and global warming is accelerating the risk. Find out about Japan's unique system for swiftly responding to fires and the latest research on forest fire mitigation.

Tokyo is prone to natural disasters such as earthquakes and flooding. Discover the most advanced disaster prevention technologies hidden throughout the city.

Osaka, a city that thrives on rivers, has faced countless flood damage. Find out the latest measures protecting the city from typhoons and heavy rain.

Find out about Japan's emergency food options that meet the needs of various people. Also discover the rolling stock method, a smart way to stockpile emergency food.

In this episode, we look at Japan's efforts to improve tsunami evacuation, from overcoming "normalcy bias" that causes people to underestimate risk, to the installation of coastal evacuation towers.

Be earthquake-ready! Learn survival tips for quakes and when you're trapped under rubble. You'll want to watch this before your next trip to Japan.

What does it take to survive a flood? Japan has developed survival skills for floods through experiences such as typhoons. Find out how to safely navigate flooded streets and escape sinking cars.

Drones are proving particularly useful in the area of disaster response. Now, Osaka University is developing the world's first system to project evacuation information in the air.

The world's first robot fire brigade has been developed in Japan. See how these incredible robots equipped with AI can tackle large-scale fires in areas that are inaccessible to humans.
