The obviously abnormality of solution gas in No.1 Panjin well was observed almost a month before the earthquake occurred on 29 November 1999 in Xiuyan. We observed a mass of hydrogen before the earthquake what generally very little can be observed. The abnormality of hydrogen was a month or so prior the earthquake, keeping pace with small earthquakes activities in epicenter. All of the basic content of an exception were positive. The author studied the abnormality of solution gas in No.1 Panjin well before the earthquake occurred on 29 November 1999 in Xiuyan.
