This is the third earthquake of magnitude 7 or greater to have occurred in the world this year.

And we can see that they are occurring frequently in Japan. Japan is a country prone to earthquakes.

The damage estimates for the Nankai Trough mega-earthquake have been revised for the first time in 11 years.

The Nankai Trough is a deep trench-like topography that exists on the ocean floor from Suruga Bay on the Pacific coast of Japan to the Hyuga-Nada Sea off Kyushu.

The Philippine Sea Plate subducts under the Eurasian Plate here, and it is known as an area prone to mega-earthquakes. Specifically, it could affect a wide area, including Shizuoka Prefecture, Aichi Prefecture,

Mie Prefecture, Wakayama Prefecture, Tokushima Prefecture, Kochi Prefecture, Ehime Prefecture, and Oita Prefecture.

Summary of the report on the Nankai Trough mega-earthquake

Estimated damage: Maximum death toll of approximately 298,000 people. Approximately 2.35 million buildings completely destroyed. The main causes of death are building collapse, building fires, and tsunamis.

Progress in countermeasures: Improvement in the rate of earthquake-proofing of homes. Improve the rate of coastal embankments.

Causes of increased damage: Increase in seismic intensity distribution and tsunami inundation range due to high accuracy of ground and topographical data.

Increase in infrastructure damage (power outages, number of evacuees). Estimated number of disaster-related deaths. Estimated damage from a half-broken earthquake.

Effects of measures: Compared to the basic plan, the number of deaths and the number of completely destroyed buildings have decreased. However, this does not reach the goals of the basic plan.

What we need to do

Strengthen disaster prevention measures: Further promote earthquake resistance of homes to prevent buildings from collapsing. Review tsunami evacuation plans and establish a system that allows for rapid evacuation. Thoroughly implement fire prevention measures and take measures to prevent the spread of fire.

Strengthen infrastructure: Implement multiple power supplies and develop a system for early recovery as a measure against power outages.

Strengthen the securing and operating systems of evacuation shelters to improve support for the lives of evacuees.

Prevent disaster-related deaths: Establish a system for health management and medical support during evacuation.

Strengthen measures for people who particularly need support, such as the elderly and disabled.

Responding to a half-earthquake: Develop evacuation plans and response measures for earthquakes that occur with a time lag.

Establish a wide-area coordination system to enable swift rescue and support activities.

Mitigating economic damage: Develop a business continuity plan (BCP) and aim for the early restoration of economic activity.

Draw up reconstruction plans in advance for affected areas and support rapid reconstruction.

Since we don't know when it will occur, advance preparations are necessary. There's no other way than to start with what we can do (earthquake resistance and fire prevention).
