Geology and tectonics of the basin of Mexico and their relationship with the damage caused by the earthquakes of September 1985

Summary The earthquakes of 19 September 1985 (18.2° N, 102.7° W and a magnitude of 8.1 Richter scale) and of 20 (17.6° N, 101.8° W and a magnitude of 7.5 Richter scale) September 1985, caused the total or partial destruction of more than 2000 structures in Mexico City. The most affected areas are located along the fringes of and bordering old roadways, earthworks (dikes), aquaducts and pre-hispanic population centres. Ancient construction artificially modified the sedimentation in the basin of the Mexico Valley Lakes making the sub-soil of Mexico City more rigid near to the surface, and producing deviations of the surface seismic waves (Rayleigh waves and Love waves). Also, when earthquakes occur on the Pacific coast, seismic waves travel quickly through plutonic, metamorphics and continental and marine rocks of different ages, having high seismic velocities. When the seismic waves enter the poorly consolidated lake sediments having low seismic velocities in the Mexico City Basin, they produce an energy buildup that causes the phenomenon called magnification.There exists a direct relation between the amplification mentioned above and the presence of rigid bodies that are buried in the sub-soil. The length of these bodies is of the order of tens of kilometres horizontally with thicknesses less than 50 metres. These Rigid Barriers produce reflections and refractions of the surface waves along their borders with destructive consequences for the buildings. A correlation between the buildings and the houses damaged and destroyed and the location of the prehispanic construction on the sub-soil has been made which shows that the most damage happened in the borders of old roadways (i.e. Tlalpan road), perimeter walls (i.e. San Lazaro), aqueducts (i.e. Chapultepec Avenue), pyramids (i.e. Templo Mayor) and population centres (i.e. Tlaltelolco).     

西藏纳木错第四纪湖泊沉积与湖成地貌--兼论藏北高原古大湖问题

对西藏面积最大的湖泊——纳木错湖相沉积野外现察结果，发现了由水平层理十分发育的砂与粘土所组成的、高出湖面分别为3—12m、15—22m、25—30m与35—45m的4级湖岸阶地，覆于基岩之上、高出湖面60—150m的湖相沉积和多达50条左右、由扁圆湖滨相砾石所组成的湖岸堤，环湖广泛分布的湖成地貌。在连结纳木错与其西北的仁错约玛、仁错贡玛、久如错的分水岭宽谷底部(分别高出上述3湖20m、90m与60m)与北侧山坡，即纳木错的第二与第三级湖岸阶地，发现了组成阶地与异堤的湖相与湖滨相沉积。从而确证了纳木错与仁错-久如锴曾多次连通，即数度成为一个统一的大湖，而不是以河道相连的不同湖泊。古大湖分离时代为末次冰期间冰段。

Experimental investigation of the earthquake response of a model of a marble classical column

Experimental results concerning the earthquake response of a marble model of a classical column are reported herein. The model was a 1: 3 scale replica of a column of the Parthenon on the Acropolis of Athens, made from the same material as the original. Several earthquake motions, scaled appropriately in order to cause significant rocking but no collapse of the column, were used as the excitation. The base motion was applied in plane (in one horizontal and the vertical direction) or in space (in two horizontal and the vertical direction), using the shaking table facility at the Laboratory for Earthquake Engineering of the National Technical University of Athens. It was found that the column might undergo large deformations during the shaking, which are not necessarily reflected by the residual displacements at the end of it. For planar excitations, significant out‐of‐plane displacements can happen, triggered by the inevitable imperfections of the specimen. It was also verified that the response is very sensitive, even to small changes of the geometry or the input motion parameters. For this reason, the experiments were not repeatable and ‘identical’ experiments produced different results. Copyright © 2002 John Wiley & Sons, Ltd.

四川茶马古道交通变迁对沿线商贸型古村镇演化的影响

茶马古道作为西南地区重要的贸易线路和移民通道,长期进行的贸易活动和人口迁移促进了沿线地区商贸型古村镇的形成和演化。以茶马古道四川段为例,基于最邻近指数、Ripley's K函数、核密度分析、重心分析等空间分析和计量地理方法,探讨古道交通变迁对商贸型古村镇分布演化的影响及其作用机制。研究结果表明：①四川茶马古道的交通变迁过程可分为两个阶段,明清以前主要分布在岷江上游地区,沟通川西盆地和黄河上游的河谷草原,明清以后主要分布在川西藏区,连接着川西和藏东南。②四川茶马古道交通变迁影响了沿线商贸型古村镇的分布格局、演化重心和演化方向。从先秦两汉至隋唐五代时期,商贸型古村镇呈现出从雅安一带往都江堰,沿岷江北上向茂县、马尔康方向演化,直至宋元明清时期,转向川西地区集聚。演化重心呈现出从雅安往北、再回到雅安一带并往西迁移,Ripley's K函数定量描述了商贸型古村镇这一外向扩散和内向集聚的过程。③古道的空间路径、地域环境、贸易政策、古村镇居民等因素分别对商贸型古村镇的演化产生主导、驱动、调节和反馈的作用机制。
