So-called “compound disasters” are wreaking havoc.
In late June, Typhoons No. 7 and No. 8 struck Japan, leaving a trail of destruction across various regions; on top of that, earthquakes occurred with epicenters in eastern Yamanashi Prefecture and off the coast of Iwate Prefecture. The Japanese archipelago was hit by a succession of disasters, akin to a wave of attacks.
Meanwhile, a series of major earthquakes struck northwestern Venezuela. A magnitude 7.5 earthquake occurred just 39 seconds after a magnitude 7.2 earthquake, causing immense damage. This phenomenon, known as a “doublet earthquake” (or twin earthquake), is considered extremely rare.
Japan has a proverb: “A bee sting on a tear-streaked face.” It describes a situation where one misfortune follows another, compounding an already painful plight; “compound disasters” are the very embodiment of this saying.
While one might assume—or wish to believe—that compound disasters are rare occurrences, we must take seriously the reality that they have happened in quick succession in both Japan and Venezuela.
Japan is considered a nation prone to disasters; it is said to possess a higher level of disaster awareness and more advanced disaster-prevention technology and know-how than other countries.
Yet, even in Japan, our preparedness for “compound disasters” may not be particularly robust. Because these events rarely occur, there is a lack of relevant information and knowledge; however, moving forward, it will likely be necessary to devise measures that specifically anticipate and mitigate the risks of compound disasters.
While the foundation lies in measures for individual disaster types—such as those for earthquakes or torrential rains—the key is to layer these strategies and formulate the most efficient, integrated approach. Regional characteristics must also be taken into account, as some areas are prone to earthquakes while others are susceptible to heavy rainfall.
Japanese summers have now effectively become a “disaster season.” Regrettably, it is anticipated that some regions will suffer significant damage from natural disasters this summer as well.
It is time for us to brace ourselves. (Kei Kitajima)
