Japan's deadly game of nuclear roulette
By LEUREN MORET
Special to The Japan Times
Of all the places in all the world where no one in their right mind
would build scores of nuclear power plants, Japan would be pretty near
the top of the list.

Enrichment in Earth's crust
Many analyses have been made of the uranium in the rocks forming the
continental and oceanic crusts, and in samples of the Earth's mantle
exposed as uplifted slices in mountain belts or as 'xenoliths' in
basalts and kimberlites (hosts of diamonds).
We can have some confidence that these measurements are robust for the
crust and upper mantle of the Earth, but less confidence that we know
the abundance of uranium in the lower... 阅读全帖 |

卑诗大学地球及海洋科学系教授赫恩(Elizabeth Hearn)表示,上次卑诗的9级地震发生在1700年1月,至今已有310年。研究表明,未来50年温哥华岛沿岸发生9级地震的可能性是22%。她估计,强度约达9.3级,比这次日本仙台的8.9级还强。
赫恩说:「地震可能将于明天发生,也可能100年后发生,没有人知道。强烈地震将带来巨大海啸,除可能引发海水倒灌外,老旧高楼可能被震毁。」

她分析,受温岛阻挡,当海啸抵达乔治亚海湾(Strait of Georgia)内的烈市及温市时,威力将减弱,估计最高仅一米,但强震产生的剧烈摇晃,对烈市及温市中心高楼大厦威胁很大。目前大温建筑抗震标准为可抵抗9.0级地震,但一旦强度达9.3级,安全性就很难说。

when the next powerful quake strikes, probably within 30 years, even though
the state prides itself on being on the leading edge of earthquake science.
Modern skyscrapers built to the state's now-rigorous building codes might
ride out the big jolt that experts say is all but inevitable, but the
surviving buildings will tower over a carpet of rubble from older structures
that have collapsed.

带下周有可能发生大地震。一系列小规模地震正从美国华盛顿州开始,北上卑诗。
不过地震专家罗杰斯(Gary Rogers)同时表示,尽管大地震发生的可能性大大提高,
但是发生机率仍然处于低水平。此前,罗杰斯和地质局其他科学家此前已经预测到了从
华盛顿州沿海到温哥华岛一带的微小地震。
“这是首次可以对发生在主断层带上的地震时间进行预测。”罗杰斯说。“目前这一断
层带的底部正在塌陷,而每次塌陷都会增加顶部发生大规模地震的可能性。” 罗杰斯
和他的同事目前正在对一种被称为“隐没带慢地震”(episodic tremor and slip)的
现象进行预测。这种现象大约每14个月发生一次。
“卑诗现在正处于一个高危险期,未来一周左右,处于卡斯卡迪亚地层潜没带(
Cascadia subduction zone)的卑诗南岸地区将可能发生大规模地震”。罗杰斯解释说
,每次慢震会对卡斯卡迪亚地层潜没带造成压力,因此提高大地震发生的机率。
但罗杰斯同时强调,目前科学家尚不能准确预测大地震的发生。他认为如果这次大地震
