Measures for lightning and thunder

1. If you hear thunder, seek shelter quickly in a nearreinforced concrete building or in a car. The best place to take shelter is in a reinforced concrete building, in the middle of a room or in a car.

2. Unplug appliances and turn off circuit breakers. Even indoors, proximity to poles and appliances can be dangerous. Lightning currents can also flow through wires and cables such as TV and telephone lines, so it is important to stay away from household appliances and avoid touching them. It is necessary to install protective equipment inside the building.

3. Do not take shelter from the rain on or under tall trees. When lightning strikes a tree, it will also pass through people close to the trunk. To avoid being struck lightning from a tree, keep at least two meters away from the tree branches.

4. Do not take shelter from the rain under the eaves. If lightning strikes the house where you are sheltering from the rain, a large current will flow through the eaves. It is more likely to pass through wetter bodies than through walls and columns that are less permeable to electricity, so the lightning current is likely to be carried partially on the side strike. The best place to take shelter from the rain is inside a building, not under the eaves.

5. If there is no place to take shelter nearby, keep as low a posture as possible.

6. Check the weather forecast and lightning forecast before leaving home.


The mechanism of a heavy snowfall

The Japan Sea side of the country usually receives a lot of snowfall in winter.

This is due to the cold, dry monsoon winds from the Siberian highlands that occur in northern Japan during winter, absorbing large amounts of water vapor as it crosses the Japan Sea, cooling it as it rises into the mountains of Japan, and falling as heavy snow.

During blizzards, buildings may collapse, crops and agricultural facilities are damaged, power and water are cut off, communication facilities are disrupted, and villages are isolated.

Blizzards can also cause avalanches and landslides, disrupting transportation such as roads and railroads. Personal safety is also threatened.


The phenomenon of infectious diseases

An epidemic is a simultaneous outbreak of the same infectious disease within a short period of time.。

Epidemics can be transmitted airborne infection, droplet infection, contact infection, oral infection, through the skin, the blood, and other modes of infection.

The mode of infection will mutate during the epidemic and there may be new discoveries, so please keep yourself updated.

There is a difference between the strength of infection, of the mild symptoms after infection, and with the immediate onset of symptoms.

It is also possible that the disease may have spread before symptoms are detected and isolation/quarantining and observation are required immediately after symptoms are know to be present.

Epidemics with high aggressiveness are generally lethal and leave sequelae or associated diseases.
