近年、集中豪雨が頻発する中、豪雨に伴う各種 災害への備えがますます重要となっている。
In recent years, heavy rain has been occurring more frequently in concentrated bursts, making it increasingly important to prepare for various natural disasters caused by heavy rainfall.
。
Normally, when the observed rainfall exceeds 30 mm per hour, roads become flooded like rivers, increasing the risk of pedestrians slipping or being swept away.
。
Furthermore, if heavy rain exceeding 50 mm per hour falls, water will overflow from manhole covers, a large volume of water will flow into low-lying areas, and there will be a risk of flooding in subway stations and underground spaces.
。
Furthermore, if record-breaking heavy rain exceeding 80mm per hour occurs, it is also possible that a large-scale disaster causing loss of life could happen.
。
Therefore, it is most important to quickly evacuate to a safe place.
。
In addition, during heavy rain, disasters such as landslides and mudslides are more likely to occur in mountainous areas.
。
Signs of an impending disaster may include hearing strange noises from the mountains, small stones falling, cracks appearing on mountain slopes, or sudden bursts of water gushing from the ground.
。
If you notice any of these signs, you should evacuate to a safe place immediately.
。
If evacuation is difficult, stay on the second floor or higher of a sturdy building and choose a room away from the mountain side.
。
Also, each local government provides hazard maps indicating dangerous areas and evacuation centers in case of heavy rain, which can be checked on the prefecture or city websites.
。
By regularly checking the safety of your home and workplace surroundings, you can minimize damage in the event of a disaster.
