The seismic precursor abnormal information extraction of tilt solid tide usually based on the distortion, tendency, elevation, fall, break and so on characteristics of solid tide.

地倾斜固体潮分析中根据固体潮汐的畸变、趋势、上升、下降、转折等变化特征，提取地震前兆异常信息。

Based on the water tube tiltmeter observatory data, the author analyses the ground tilt tide, finds that the abnormal change of amplitude factors of EW and NS componts is corresponding to earthquakes.

对云龙台的水管倾斜仪观测数据进行了倾斜固体潮的潮汐分析，发现EW和NS两个分量的振幅因子异常变化与地震有较好的对应关系。

Some new methods, included satellite thermal IR anomaly, earthquake cloud, double magnetic storm time method, the abnormal superimposition of tide-generating force resonance and so on, are introduced.

地震预报，特别是短临预报一直是个世界性的科学难题。介绍了几种地震预报的新方法、新途径，包括：卫星热红外异常法、地震云法、磁暴二倍法、引潮力共振的异常叠加法等。
