River's ammonia levels rise befor quake

地震前 河水中阿摩尼亞濃度升高

River's ammonia levels rise befor quake
A Taiwan academic has discovered that before a major earthquake hit central Taiwan September 21, 1999, ammonia density in a river in that area rose 20 to 40 fold higher than usual, a discovery that he has sent to an international journal for publication.

一名台灣學者發現,台灣中部在921地震侵襲之前,一條河流中的阿摩尼亞濃度比平常上升二十至四十倍之多,這項新發現已經送交國際期刊出版。

Liu Chiung-pin, an assistant professor of National Chung Hsing University, started to gather water samples from the upper reaches of Kuantao Creek in Nantou County in 1994 under a program funded by the National Science Council. Twice each month, she tested 17 chemical elements in the river.

國立中興大學助理教授劉瓊霦在1994年一項由國科會資助的研究計劃中,開始收集南投縣關刀溪上游的溪水樣本,每個月她總共檢驗水中化學物質兩次。

Right before the September 21 earthquake, Liu said, the ammonia density gradually rose by 20 to 40 times from August 1998 to September 1999, and the density has remained high until the present. At the same time, she noted, the potassium density went down three to five times and the magnesium density dropped 10 to 15 fold.

劉瓊霦表示,在921地震前,阿摩尼亞濃度在1998八月至1999年九月間上升二十到四十倍,截至目前濃度仍然很高,同時她也指出,鉀濃度降低三到五倍,鎂濃度降了十到十五倍。

Liu said he has searched international science journals and has found nothing to explain similar phenomenon except one report about Kobe, Japan, which was hit by a major earthquake in 1995. The report, which appears in Science magazine, said that five months before the January 1995 earthquake, chlorine and sulfuric acid levels in Kobe's underground water rose conspicuously.

她表示在搜尋許多國際科學期刊後,仍未發現任何與之相似現象的解釋,除了發表於《科學》雜誌中的1995年日本的神戶大地震,內容說明在1995年一月地震的五個月前,神戶地下水中的氯與硫酸根濃度顯著提高。

Liu said that before an earthquake, microbes and chemical compounds in the soil might change, but she added that he does not know what kinds of microbes might have died to cause the chemical changes in the water.

劉瓊霦表示,地震之前土壤中的微生物與化學成分可能產生變化,她並補充道,但仍不知何種微生物可能死亡而造成水中的化學變化。
