Proposal of a Recommended Correspondence Method for Companies and Organizations in Case of Partial Rupture of the Nankai Trough Earthquake

The occurrence rate of a subsequent earthquake is es-timated to become a hundred times more than that at ordinary times when a case of partial rupture of the Nankai Trough Earthquake occurs. Companies and organizations that play a key role in social activ-ities should take practicable actions positively in co-operation with relevant actors. Their recommended correspondences would be different by area accord-ing to the influence level by the subsequent partial rupture earthquake. Areas would be classified into three types: 1) strong earthquakes and tsunami are anticipated, 2) strong earthquakes without tsunami are anticipated, and 3) neither strong earthquakes nor tsunami is anticipated (this area should contribute as a supporter). There is also difference depending on business character and industry type. Therefore, it would be effective to examine the responses in the case of partial rupture, counting these differences in, and based on their business continuity plans (BCP). The authors will propose a recommended correspon-dence method (recipe) as an example of this means. In addition, there should be recommended actions of companies and organizations such as their operations not preventing evacuation and stockpiling in the local communities.

Automated summary

The occurrence rate of subsequent earthquakes is projected to be a hundred times higher than normal when the Nankai Trough Earthquake experiences partial rupture. Companies and organizations that play important roles in social activities should cooperate and take feasible actions. The recommended responses would vary based on the level of influence from the subsequent partial rupture earthquake.
