Evacuation Instruction*1: Alert Level 5 is not always issued due to a number of reasons, such as municipal authorities being unable toaccurately grasp the severity of the disaster.
*2: At Alert Level 3, everyone should adjust their daily activities as needed and prepare to evacuate. If they feel that
their safety is threatened, they should evacuate voluntarily.

Evacuation information is issued when danger is imminent, and residents need to evacuate. The two types of information areissued according to the severity of the situation. Take evacuation actions accordingly.

2 Evacuation Instruction

A situation in which there is an extremely high risk of humancasualty, or if the human casualty has already occurred.

(1) Nankai Trough Mega Earthquake
An earthquake with the epicenter in the Nankai Trough shown in (1) on the map above. A huge earthquake will occur when theTokai, Tonankai, and Nankai earthquakes occur together and when the epicenter expands further into the Hyuganada Sea.

to prepare to evacuate by contacting family members, preparing
an emergency bag, and others.

〇Evacuate immediately if you have started evacuating.
〇Evacuate immediately if you haven't started evacuating. If evacuation is no longer possible, take immediate life-saving actions.

If you're already in a safe location, you don't need to go to an evacuation shelter.
If there is no danger of ﬂooding or landslide disaster, and if you're able to stay in your home, please prepare your home bystockpiling disaster supplies to use your home as a shelter.

Assumed conditions of the tsunami height noted above

If you need to evacuate to somewhere other than your home, consider evacuating to a relative's or friend's house in asafe area to the extent possible to prevent overcrowding evacuation shelters.

▶Evacuate to an evacuation shelter if doing (1) or (2) is diﬃcult.
The principle is that people in dangerous places should evacuate.

Beppu Bay fault zone: Almost 0%

Beppu Rift Southern Fault Zone: Approx. 0.03-4%(3) Earthquakes caused by active faults in the Suonada sea

After checking the danger level of where you are on a disaster prevention map, follow the steps below todetermine where to evacuate.
Consider (1) or (2) first to prevent the risk of infection.
