Japan’s recent earthquakes have triggered a national debate about how to prepare for future earthquakes, as well as how the country’s national government should respond to future tremors.
As Japan prepares for the possibility of more powerful earthquakes, the government has put forward a number of ideas to help protect people and property in the future.
One proposal is to build large underground tunnels for the purpose of providing emergency protection from earthquakes.
However, experts say this approach will cost money and will require significant changes in infrastructure.
The Japan Earthquake Protection Agency (JEPRA), which was set up in 2006 to provide earthquake protection in Japan, has proposed building an underground network of underground tunnels to protect buildings, public spaces and people from future earthquakes.
The tunnels would be constructed underground, and people would have to stand outside while underground construction is being carried out.
Experts say this would pose a major security risk for Japan’s vulnerable population, who are already living in crowded, crowded urban environments and are at risk from landslides.
This new plan is the latest attempt to develop a new system for earthquake protection and is aimed at reducing the cost of building the tunnels, as the underground system would have much lower maintenance costs than traditional concrete buildings.
According to the JEPRA proposal, the tunnels would include three underground passages, one for each of the five main earthquake zones.
Each passage would have four floors, and each floor would be at least 100 metres in diameter.
Each tunnel would be able to contain around 10,000 people and have a capacity of more than 2,500 people.
The tunnels would also be equipped with automatic doors, elevators, fire alarms and other security measures.
As the tunnels were designed to be a temporary solution, they would not be able go on forever.
They would be replaced with permanent solutions that could be maintained and repaired.
In addition, the tunneling system would be built so that the tunnels could be used for various purposes.
The JEPRC proposal would also build a network of tunnels in Tokyo’s subway system, to provide emergency emergency protection for people who use the subway system.
While Japan’s government has said that the underground tunnels would not last forever, experts have expressed concern about the possibility that these underground tunnels could collapse during an earthquake.
In the past, there have been numerous earthquakes that have struck in Japan.
In one such incident in the late 1970s, more than 3,000 residents of a nearby suburb died when a magnitude-7.8 earthquake hit.
Since then, Japan has suffered more than 6,000 earthquakes.
However, the number of earthquakes that Japan has recorded in recent years has been declining.
In 2015, Japan recorded just 2,737 earthquakes, and it recorded just 651 in 2017.
According the JepRA, the cost to rebuild an underground tunnel would range from ¥3,000 to ¥6,000.
The cost to construct an underground structure would range between ¥7,500 to ¥15,000 per structure.
The JEPRLA said it hoped that the cost savings of the underground plan would be passed onto residents, businesses and public buildings.
experts said this would require significant structural changes to Japan’s infrastructure.
Experts also said that this proposal could not provide a long-term solution.
“If we want to prepare people for the future, we should be building the right type of infrastructure and not the right kind of tunnels,” said Hiroto Kobayashi, a senior lecturer at Kyoto University’s Centre for Earthquake and Engineering Studies.
