据《苏维埃吉尔吉斯报》1980年7月19日报道:当地球深部某处在释放大量能量时,地球表面还显得很平静。此时,在大气的电离层内,从未来地震的震中向很远处传播声波,其频率达数十万赫兹。这一现象是塔吉克的学者们发现的。塔吉克抗震建筑和地震研究所所长、塔吉克共和国科学院通讯院士涅格马杜拉也夫说:“在塔吉克,每年记到一千次以上不同性质和强度的地震。” According to the Soviet Kyrgyz newspaper, July 19, 1980, the surface of the earth appears calmer when large amounts of energy are released somewhere deep in the Earth. At this moment, sound waves are transmitted very far from the epicenter of the future earthquake within the ionosphere of the atmosphere, which reaches several hundred thousand hertz. This phenomenon was discovered by Tajik scholars. “In Tajikistan, more than a thousand earthquakes of different nature and intensity have been recorded each year,” said Nigemadulalah Yev, director of the Tajik earthquake-resistant buildings and seismology institute and communication commissioner of the Tajik Academy of Sciences.
