中文摘要：

近年来,我国大陆西部地区破坏性地震频发。通过地震现场的烈度考察和灾害调查等工作,迅速向社会公开发布地震烈度图,为地震应急救援、灾后恢复重建发挥重要作用。该文通过剖析2013年4月20日芦山7.0级地震烈度,发现其主要依据是居民点建筑物的破坏情况,和以滑坡为主的其他次生山地灾害、峰值加速度等代表的强地面运动分布存在显著差异,而受发震构造、震源分布、破裂过程、震源机制等因素约束不强。另外的几次地震也存在类似问题,并且有的地震修订烈度图可能不利于使用,所有地震都没有烈度异常区（点）,越来越近似于共焦点等间距椭圆,烈度图的科学性存在疑问。针对这些问题,进一步提出对烈度速报问题的认识和展望。

英文摘要：

In recent years, destructive earthquakes take place frequently in the western region of China. In accordance with the requirements of the China earthquake administration, earthquake field work team should quickly rush to the earthquake site to carry out relative intensity investigation and disaster investigation etc. and release the seismic intensity map to the public within 3 - 5 days to support the earthquake emergency rescue, post-earthquake recovery and reconstruction. This paper analyzed the seismic intensity of April 20, 2013 M7.0 earthquake and found that there arc significant difference between the seismic in- tensity, which is mainly based on the damage of residential buildings, and other seismic secondary moun- tain disasters given priority to with the landslide disasters and the distribution of ground motion on behalf of the peak acceleration, etc. Furthermore, the seismic intensity is not well consistent with the seismogen- ic structure, source distribution, failure process and focal mechanism. Another few earthquakes have similar problems. Moreover, some seismic intensity map revision is not conducive to use. With no intensity a- nomaly areas （points）, seismic intensity distribution is more and more similar to total focus on space ellipse and its scientific is in doubt. Based on analysis on these problems, this paper further discussed seismic intensity rapid reporting.
