To mark the tenth anniversary of the disaster of March 11, 2011, we are posting one of the chapters from the book we are working on about Japanese housing. Some of the following appeared in slightly different form in the anthology known as #quakebook. For those who may be interested, we have been looking for a publisher or agent to handle the book for the last year and so far have had no luck in placing it, so if anyone has advice, connections, etc., let us know.
On March 11, 2011, the governor of Tokyo was Shintaro Ishihara, who later called the massive earthquake that struck off the coast of northern Japan that day “divine retribution” for some imagined slight to the nation’s soul. Never mind that all of the people who died or were left homeless by the disaster had lived in three northeastern prefectures far from the fleshpots of the capital he oversaw. Ishihara, a popular novelist in addition to being a politician, needed to make some sort of apocalyptic statement.
No one thought there was anything “divine” about the catastrophe, but we could all appreciate a cosmic joke. The quake hit right in the middle of moving season. The Japanese fiscal year, not to mention the school year, begins April 1, and traditionally many people move house during the month of March because of changing jobs and entering university. Consequently, before, during, and after the quake there were moving trucks parked outside our 38-story apartment building in the Minami Senju area of Tokyo, carrying furniture for people who were settling in. Elevators in Japan are designed to automatically shut down in the event of an earthquake and they can’t be restarted until a technician arrives to turn them on again. Given that the entire city was affected, some buildings had to wait hours or even a day before someone showed up to get the elevators working. Movers were stuck on the street with trucks full of furniture while their customers stood in their new apartments appreciating the view as they swayed back and forth during one of the aftershocks that occurred on an almost hourly basis. Did they regret their decision to move into a high-rise?
Perhaps not. The disaster helped answer a question: Would all these quake-proofed structures that had been built in the previous decades actually withstand a massive earthquake? Of course, the epicenter of the one we had just experienced was hundreds of kilometers away, but no buildings had collapsed in Sendai, the major city nearest to the quake and one with its own share of high-rises. So the technology seemed to work. But while it saved lives and property, it didn’t solve a more intractable problem: Once you’ve been in a major earthquake in a tall building, you don’t want to be in another one.
We had already been living on the 24th floor of River Harp Tower for more than ten years when the quake struck at 2:46 that afternoon, and had been through a good share of them. They just weren’t as intense. Usually, they started with a jolt followed by a gentle swaying. There are two types of quake-proof technologies for high rises in Japan. One is designed for flexibility: the entire structure absorbs the energy and disperses it more or less evenly throughout the frame, and the higher your floor, the wider and longer the sway. The other type, which is more expensive, involves rubber dampers in the foundation. We lived in the former type. On March 11, we didn’t feel that usual initial jolt but rather a slight rumble from the floor that just kept building until the walls started rattling violently. We knew this was going to be bigger than the usual quake and crouched together under a table. The shaking continued, and then gradually changed to swaying, which was much wider than it had been in the past. But the movement wasn’t as scary as the noise: a massive creaking sound that went on for more than two minutes.Read More
