The Philippine Institute of Volcanology and Seismology raised the alert level up a notch on Monday night to level 3. Scientist Alex Baloloy told the Philippine News Agency that under level 3,"a full-blown eruption is expected to take place within weeks to days."

菲律宾的火山和地震学会周一晚提升了警报等级为3级，科学家Alex Baloloy告诉菲律宾新闻机构说，低于3级，一次全面的喷发预期在未来的几天到一周时间里。

Late Dec The Mayon Volcano in the Philippines was showing violent activities, and the Philippine Institute of Volcanology and Seismology raised the alert to level 4 on December 20, indicating a violent eruption is likely in the next few days.

20(12月下旬)菲律宾马荣火山出现剧烈活动，当地火山学及地震学研究所於 20 日将警告级别提升至 4 级，表示猛烈爆发可能於未来数天出现，约五万人需要撤离。

But classical rough set are based on indiscernibility relation or similarity relation. The problems in Seismology deal with ordering objects instead of classifying objects.

但是，经典的粗糙集理论建立在由等价关系对对象集划分的基础上，而震例数据是有序的而不是分类的对象。

First, based on the analogy of the mathematical expressionbetween the propa gation of EM wave and that of seismic wavein a horizontal stratified earth, the re flectivity and transmissionformulation for EM plane wave propagating incident nor malto the layers are derived, the formulation with relation to pseudo-impulse is discussed and pseudo-impulse response is compared with impulse response of re flection seismology.

作者首先基于电磁波与地震波在水平层状介质中传播特征在数学形式上的相似性，推导了垂直入射平面电磁波在层间反射与透射传播函数，并讨论了它们与伪脉冲的关系，与反射地震学中脉冲响应作了对比。

May or not be quake is occur with look up see chandelier to know". Because of a lofty overhang chandelier very sensitive to ground plane motion and it is shaking repeatedly by action of inertia force during a quake happen. In 19 century, a" zhong you du zhu "of ancient Chinese seismographic phrase was translated "one stick in the middle and it is hanged by the ancestor Ernt of modern seismology .

地震没地震，抬头看吊灯&，就是因为高高悬垂的吊灯对地面的水平运动非常敏感，会因惯性不停摇摆。19世纪，现代地震学鼻祖米尔恩把&中有都柱&译成&中间有一根柱子，这根柱子是悬挂起来的。

Meanwhile,the rate of accumulation of broadband digital seismologic observation data is increasing exponentially,meaning that the research on high resolution seismic imaging of earthquake source rupture process and internal structure of the earth will be an important development trend of seismology in the 21st century.

与此同时，宽频带数字地震观测资料的积累速率按指数增长，这意味着震源破裂过程及地球内部结构的高分辨率地震成像研究将成为21世纪地震学发展的重要趋势。

The relationship between research on seismology and on dynamics of the earth will be closer and closer with each passing day,the role and importance of broadband mobile seismologic observation will certainly grow day by day.

地震学与地球动力学研究的关系将日趋紧密，宽频带流动地震观测的作用和重要性必将与日俱增。
