地震が起こる確率｜Probability of an Earthquake

防災講習で起こるメカニズムを説明してくれた。地球の地下のプレートが毎年５センチや８センチずつずれ、ある一定の数値になると戻る力が働き、地震が起こる。そのため100年から150年の周期で大地震が起こるし、今後30年に大地震が起きる確率も70%になるという。それらのことはなんとなく聞いたことがあったものの、全体像を理解することは初めてだった。毎朝規則正しく朝が来るような自然界の法則で言えば、この確率は極めて高いんだなぁと思うし、起こらないという選択肢はないんだなと思う。そう思ったらすぐに対策だ！（絵と文：サカキテツ朗）

I was explained the mechanism that occurs in the disaster prevention course. The Earth's underground plates shift by 5 to 8 centimeters every year, and when they reach a certain scale, the forces of return act and earthquakes occur. Therefore, large earthquakes occur in cycles of 100 to 150 years, and the probability of a large earthquake occurring in the next 30 years is 70%. I had heard about them vaguely, but it was the first time I understood the whole picture. In terms of the law of the natural world that morning comes regularly every morning, I think this probability is extremely high, and I don't think there's an option that it won't happen. If I think so, take measures immediately! -Text and illustration by Ted Sakaki
