唐山地震后,不少同志在探索着各种前兆的规律。地震刊物一九八○年第一期“水氡异常场讨论”一文的作者认为:唐山震前水氡异常特征“最突出的是中期异常所具有的同步性,……”并提出“振动是引起大面积同步异常的主要原因”。我认为“讨论”中提出的“同步性”值得进一步商榷。唐山震前水氡中期异常
After the Tangshan earthquake, many comrades are exploring the laws of various precursors. Earthquake publication The first issue of “Discussion on abnormal water radon anomalies” in 1980 first considers that the most prominent feature of water radon anomaly before Tangshan earthquake “is the synchronicity of mid-term anomalies ...” and proposed that “the vibration is Cause a large area of the main reasons for abnormal synchronization. ” I think the “synchronicity” put forth in the discussion deserves further discussion. Mid - term anomalies of water radon before Tangshan earthquake
