Kagawa Prefecture has long been known as a place with little rainfall and few disasters. Recently, however, due to global warming, more rain than expected has been falling in a short time even here in Kagawa Prefecture, and the risk of disasters such as river flooding and landslides has been increasing. To protect our own life, we should check the hazards around us at least once.

Incidentally, the magnitude of the tremor near Kagawa University's Saiwai-cho campus in the event of a Nankai Trough earthquake is "Seismic intensity 6 upper".

* This seismic intensity scale is used only in Japan.

This "seismic intensity 6 upper" means that
・It is impossible to move without crawling, or risk being blown away.
・Most of the unsecured furniture will be shaken and many objects will fall over.
・Many wooden buildings with low earthquake resistance will lean over or collapse.
・Large ground cracks, large landslides may occur, and mountains may collapse.
