【摘要】 在北纬 2 1°～ 2 6° ,东经 119°～ 12 3°内 ,依据板块运动、地体构造界线、活动断层分析和强震震中分布四个因素 ,绘制台湾地区的地震地体构造区分图 ;将台湾地区分成东西两个地震区 ;E1～E4、W1～W4等共八个地震带。根据强震幕式分析、地震活动性水平分析、地震频次与缺震异常分析和空区与条带分析四个地震趋势分析步骤 ,分析 2 0 0 1年和 2 0 0 2年台湾地区的中强地震趋势。实际地震结果表明 ,这种地震趋势分析方法在台湾地区有非常好的应用效果。更多还原

【Abstract】 Seismic terrain tectonic zoning map for Taiwan area in 21°～26° N and 119°～123°E is made according to the four factors,plate movement,terrain tectonic boundary line,active fault analysis and epicentral distribution of strong earthquakes and Taiwan area is divided as both east and west seismic areas and the eight seismic belts of E1 to E4 and W1 to W4.According to the four analytical procedures of earthquake tendency,strong earthquake episode analysis,seismicity level analysis,analysis of earthquake frequency and earthquake absent anomaly and analysis of seismic gap and belt,the middle-strong earthquake tendency in Taiwan area in 2001 and 2002 is analyzed.The results of practical earthquakes show that the seismic tendency analysis method can be applied to Taiwan area very well.更多还原
