摘　　要：2015年4月25日14时11分(北京时间),尼泊尔发生8.1级特大地震,截至4月29日,地震造成5 200多人死亡。地震引发的雪崩、滑坡、泥石流等次生灾害非常严重,致使尼泊尔8.1级特大地震具有"震级大,余震少,救援难度大,影响范围广"的灾害特点。本文通过跟踪分析研究地震暴露出来的种种现象和问题,探讨了隐藏在现象和问题背后的几个主要科学问题,即地震成因问题,宏观震中问题,地震是否预测的问题等,旨在抛砖引玉,共同推进地震科学研究向前发展。On April 25, 2015（Beijing time）, the great 8.1 earthquake occurred in Nepal, as of April 29th, the earthquake killed more than 5 200 people, more than ten thousand people were injured. Avalanches, landslides, debris flow and other secondary disasters caused by the earthquake are very serious. The disaster characteristics of the great Nepal earthquake were ＂large magnitude, less aftershocks, difficult rescue, and wide affecting range＂. In this paper, various phenomena and problems exposed from the great earthquake are analyzed. And several major scientific problems hidden behind the great earthquake, namely the causes of earthquakes, the macro epicenter problem, the earthquake prediction problems are studied, aiming to initiate, to jointly promote the development of earthquake science research.
