According to the 2020 edition of the Global Climate Risk Index, a report that ranks the impact of weather disasters such as typhoons and floods, the worst is Japan and the second is the Philippines.
In the Philippines, many houses are handmade and buildings are not as strong as in Japan. Most families are not financially able to afford to build new houses after suffering damage from disasters. In addition, over the course of the 20th century, the forest area in the Philippines decreased from 70% to 20%.
Illegal logging has occurred in the Philippines, and flood damage is becoming more severe in some areas.
Current infrastructure maintenance practices are limited to steady-state maintenance. Disaster prevention work has been inadequate and inappropriate, especially in sections with critical slopes, and improvement efforts have been limited to reopening infrastructure, resulting in repeated slope hazards and increased maintenance costs.
The method proposed in this study is not a matter of drastic solutions, but rather a system to quickly evacuate people in the event of an earthquake or a collapse, with the primary concern of saving lives!
