How Japan learns from its earthquakes and tsunamis

The 1923 earthquake that devastated Tokyo spawned a nationwide effort to prepare for future quakes. Here's a Monitor story that shows how the survivors of the Tokyo disaster helped that cause.

A famous Japanese wood-block print by Hokusai Katsushika (1760-1849) is known as "The Great Wave off Kanagawa." While it may simply depict a large ocean wave (and boats carrying fish to market), it is also often assumed to show a tsunami from an earthquake.

The Japanese reaction to Friday’s earthquake and tsunami will probably serve as lesson for other quake-prone countries. Ever since a 7.9-scale quake in 1923 that destroyed much of Tokyo, the Japanese have tried to prepared for the “big one.”

Here’s my account (written two decades ago when I reported from Tokyo) of how the survivors of that last “big one” helped keep the Japanese on their toes:

The only warning for Ichiro Uchibaba was the odd behavior of a bear, a neighbor’s pet, all excited in a cage like an old alarm clock gone berserk.

Seconds later, at just before noon on Sept. 1, 1923, the earth lurched, and all of Tokyo was jolted with a ferocity that Mr. Uchibaba will never forget.

Roof tiles went flying, pillars toppled, fires erupted, and Uchibaba was thrown to the ground. The bear, which had somehow sensed the quake coming, reached out of the cage and scratched Uchibaba’s arm.“There was no place for me to escape that quake,” he recalls. “I crawled to a moat and clung to a stick until it was over.” Eight years old at the time, he witnessed the destruction of Tokyo as the city was consumed by flames over three days, taking the lives of 140,000 people, including his parents. The quake’s intensity was later estimated to be 7.9 on the Richter scale.

The seismic upheaval was an experience that Uchibaba, as head of a group of remaining survivors, and the government do not want the Japanese to forget.

Only by keeping alive the memories of the 1923 disaster do officials hope to alert the Japanese to do more than just wait around for what is often called “the Big One.”

As a reminder of the disaster, Uchibaba keeps a clock in his home set to the exact time of the 1923 quake. And every Sept. 1, he and other survivors go to a Buddhist temple and museum built to recall the great quake.

Also on Sept. 1 every year, millions of Japanese take part in “disaster prevention” drills run by local governments. School kids put on quilted headgear and practice getting under their desks. Old folks are reminded to choose a spot to meet loved ones in case they are separated. Stores sell emergency kits of water, flashlights, and preserved Japanese food, such as pickled plums.

The Japanese need few reminders. They know that their archipelago sits at a point on the Pacific rim where three plates of the earth’s crust are colliding inch by inch, producing 30 or 40 “felt” quakes a year. Geologic instability is part of daily life in Japan. The word jishin (earthquake) is murmured with dread at every tremor.

If another big quake should hit the Tokyo area, which is now home to one-quarter of Japan’s population, it would not only affect Japan but also create aftershocks on world financial markets as the Japanese withdrew overseas investments to pay for reconstruction at home.

Around 10 years ago, many Japanese seismologists predicted that a big earthquake was possible in an area just south of Tokyo within the next few decades. An “earthquake counter-measure” law was passed to improve evacuation roads, strengthen school buildings, and construct shoreline embankments against quake-generated tidal waves.

AND to really keep people on their toes, an “earthquake simulator” was invented and put on traveling trucks. The vehicles are open on one side and contain a typical Japanese kitchen. People are invited to step in and be rocked back and forth with a rising intensity, like a raft going down rapids.
