〔★原発NEWS〕 奥尻島津波 貞観津波にも言及

 NYTのオオニシ記者らの記事は、奥尻島の津波(1993年)にも、「フクシマ」のすぐ北の内陸部、海岸から1.6キロ近くの地点まで到達しら貞観地震(869年)などにも言及している。

 「前例」は、いくらでもあったのだ。政府・東電はもう言い逃れできない。

 オオニシ記者らはそれを「海外」の研究者たちが見ている「最も悲しむべき事実」だと書いている。「国内」にいるわれわれとしても、悲しすぎる事実だ。  

 Perhaps the saddest observation by scientists outside Japan is that, even through the narrow lens of recorded tsunamis, the potential for easily overtopping the anti-tsunami safeguards at Fukushima should have been recognized. In 1993 a magnitude 7.8 quake produced tsunamis with heights greater than 30 feet off Japan’s western coast, spreading wide devastation, according to scientific studies and reports at the time.

On the hard-hit island of Okushiri, “most of the populated areas worst hit by the tsunami were bounded by tsunami walls” as high as 15 feet, according to a report written by Mr. Yanev. That made the walls a foot or two higher than Fukushima’s bluff.

But in a harbinger of what would happen 18 years later, the walls on Okushiri, Mr. Yanev, the expert in seismic risk assessment, wrote, “may have moderated the overall tsunami effects but were ineffective for higher waves.”

And even the distant past was yielding new information that could have served as fresh warnings.

Two decades after Fukushima Daiichi came online, researchers poring through old records estimated that a quake known as Jogan had actually produced a tsunami that reached nearly one mile inland in an area just north of the plant. That tsunami struck in 869.
