The Japanese authorities have published instructions on how the public should react if the famous Mount " Fuji , who should break out near Tokio . Experts recommend searching for protection at home and maintaining a two -week storage of residents. These guidelines were published last week.

activity of the Mount Fuji

Although there is no evidence that an outbreak is imminent, Fuji is considered an active volcano. His last outbreak took place 318 years ago, known as the Hoei outbreak.

preparations for a possible outbreak

"We have discussed countermeasures because there is a possibility that a large-scale, explosive outbreak, similar to the hoei outbreak about 300 years ago, could cause a far-reaching volcanic spring formation in the entire region, including the main city region," said Toshitsugu Fujii, professor at the University of Tokio Press conference.

consequences of a large outbreak

In the event of a large outbreak, an estimated 1.7 billion cubic meters of volcanic ash would be created, with around 490 million cubic meters to be deposited on roads, buildings and other land areas. This requires corresponding disposal.

protective measures for the population

"In response to the extensive ash formation, the fundamental recommendation is that the residents continue their daily life at home or in other protection accommodations. It is therefore important to create regular supplies," explained Fujii.

risks from ash elements

"However, if more than 30 centimeters of volcanic ashes accumulate, wooden houses with low load capacity can collapse under the weight, which would require evacuation," he added.

economic effects

The economic loss by an outbreak of Mount Fuji is estimated at up to 2.5 trillion yen ($ 16.6 billion). Even a small amount of accumulated ashes could bring the train operation to a standstill. Should it rain, ashes that are accumulated at more than 3 centimeters (1.2 inches) could make streets impassable.

logistical challenges

Logistics would be affected, which would make it difficult to obtain vital goods. In addition, electricity lines could break off under the weight of the ashes, which would lead to power failures.
