CHOICES OF LU』S ARTICLES (8) 呂 氏 精 選 (8) 著名地質學家張文佑
Prof. Zhang Wenyou, the Chief of Geology Department of the Chinese Academy of Sciences, the Director of the Geology Institute Provided Powerful Evidence for Predicting Epicenter through Observing Figures by Dajiong Lu
In the early period of research on earthquake prediction, Dajiong Lu found out some symptoms: observing figures recorded could predict the epicenter. Then Lu went to consult Prof. Zhang Wenyou, the Director of Geology Institute. Prof. Zhang said: 「It』s reasonable. Long ago, there was an overseas seismologist. He only needed to look at the pattern of an earthquake wave recorded, he could judge directly where an earthquake already happened, didn』t need any calculation according to earthquake waveform. Therefore, it should be feasible from logic that according to waveform of earthquake precursor you could judge directly where an earthquake would happen.」 Thereafter, Dajiong Lu made a lot of efforts to research and summarize, then obtained the concept of precursor mode for predicting epicenter and according to recorded waveform of earthquake precursor predicted epicenters of some strong earthquakes successfully.
After Dajiong Lu successfully predicted three elements (epicenter, magnitude and occurrence time) of Ogasawara Isles Earthquake and the Shock Prevention Office under the headquarters of the General Staff issued a certificate of successfully predicting this earthquake, Prof. Zhang said excitedly: 「Please give me a copy of this certificate, I』ll show it to the Chinese Academy of Sciences and State Seismological Bureau!!!」
Actually, on the basis of Dajiong Lu』s research, the precursor mode of earthquake has even more important and profound meaning and subtle function. If a new book could be published by any chance in the near future, Prof. Dajiong Lu would write this subject and a lot of knowledge, what Lu has learned but others haven』t yet, into his book.
中國科學院地學部主任, 中國科學院地質所所長張文佑
為呂大炯的」 觀察圖形預報震中」提供有力佐證
呂大炯在研究地震預報的初期,發現了」 觀察記錄圖形可預報地震震中」的一些苗頭,就去向中國科學院地學部主任, 中國科學院地質所所長張文佑請教.張教授說:」你說得很有道理.記得以前有一位國外的地震學家,他只要一看地震波形形態,就可直接判斷地震已在那裡發生了,不用根據地震波形作任何計算.因此你根據前兆波形直接判斷地震將要在那裡發生,從邏輯上看應該也是可行的.」於是呂大炯在這方面下功夫研究,總結出了預報地震震中的前兆模式概念及根據記錄圖形
成功地預報了某些強烈地震的震中位置.當呂大炯成功地預報了日本小笠原群島
地震的震中,震級與震時三要素及總參防震辦公室出具了成功預報的證明之後,
張文佑教授興奮地說:「把證明信給我,我去給他們(意指XXXX院及XX局)看!」
其實, 根據呂大炯後來的研究,地震的前兆模式還有其更加重要與深刻的含意及微妙的用處.如果以後有機會出書的話,呂大炯有可能會把這一問題及其它許多至今尚不為人知的研究心得寫在他未來的書中.
