ADVANCED GEOTECHNICAL EARTHQUAKE ENGINEERING RECONNAISSANCE

2001年1月26日上午8时46分，印度古吉拉特邦Kachchh地区发生里氏7.5级地震。这是印度近50年来最严重的地震。地震震中位于印度艾哈迈达巴德以西约160英里（250公里）或巴基斯坦海得拉巴东南约180英里（290公里）的Bacchau以北。据美国地质勘探局称，震中位于N23.399 E70.316，深度为23.6公里。地震破坏了大坝、港口和桥梁，抹杀了古吉拉特邦的小村庄，并对距离震中250公里的大城市阿赫梅达巴德造成破坏。截至2001年2月2日，印度政府农业和合作部报告地震造成15 000多人死亡。据报道，数以万计的建筑物倒塌和损坏，大量的人无家可归。2001年1月26日的地震发生在卡奇赫地区，似乎是一个板内事件，与1811-1812年新马德里序列相似，该序列于1811-1812年12月至1月袭击了密苏里州的新马德里。第一份报告显示，印度西部的破坏范围很大，就像在密苏里州的新马德里观察到的那样。伤亡和破坏的程度以及与美利坚合众国现有条件的相似性要求立即派遣一个NSF岩土工程勘察小组，以记录这次地震的岩土工程和工程地质/地震学特征。该项目提供必要的资金，以便派遣一个小型高级勘察小组前往2001年1月26日印度布杰地震受损地区。并尽可能详细地记录地震的岩土和工程地震学特征。侦察队将在紧急救援工作放缓和运输工具重新建立后立即派往印度。高级侦察队将由南加州大学的J. P.巴尔德协调。先进的侦察队之后将是一个更大的侦察队协调的雷蒙德种子的加州大学伯克利分校。这个更大的团队将得到国家科学基金会单独的SGER拨款的支持。对这次破坏性地震的拟议侦察预计将产生有用的信息和数据，以了解大规模板内事件的影响，并将这些发现应用于减轻中美洲类似地震的危害。

On January 26, 2001 at 8:46 AM (local time), a magnitude Mw 7.5 earthquake struck the Kachchh area in Gujarat, India. This is the most damaging earthquake in India in the last 50 years. The earthquake epicenter is located to the north of Bacchau about 160 miles (250 km) west of Ahmadabad, India or about 180 miles (290 km) southeast of Hyderabad, Pakistan. The epicenter was at N23.399 E70.316 and a depth of 23.6 km according to USGS. The earthquake damaged dams, ports and bridges, obliterated small villages in Gujarat, and caused damage to Ahmedabad, a large city 250 km away from the epicenter. As of 2 February 2001, the Department of Agriculture and Cooperation of the Indian Government reported more than 15,000 dead as the result of the earthquake. There are reports of ten of thousands of collapsed and damaged buildings, and a great number of people homeless. The January 26, 2001 earthquake took place in the Kachchh region, and appears to be an intraplate event with similarities with the 1811-1812 New Madrid sequence, which struck New Madrid, Missouri from December through January 1811-1812. First reports indicate that damage in Western India extends over large areas, as was observed in New Madrid, Missouri. The extent of casualties and damage and the similarities with existing conditions in the United States of America required the immediate dispatch of a NSF reconnaissance geotechnical team to document the geotechnical and engineering geology/seismology features of this earthquake.This project provides funding necessary for sending a small advanced reconnaissance team to the area damaged by the January 26, 2001, Bhuj, India earthquake, and for documenting the geotechnical, and engineering seismology features of the earthquake in as much detail as possible. The reconnaissance team will be sent to India as soon as the emergency rescue efforts have slowed down, and the means of transport have been reestablished. The advanced reconnaissance team will be coordinated by J.P. Bardet of the University of Southern California. The advanced reconnaissance team will be followed by a larger reconnaissance team coordinated by Raymond Seed of the University of California, Berkeley. This larger team will be supported by a separate SGER grant from the National Science Foundation. The proposed reconnaissance of this devastating earthquake is expected to yield useful information and data to understand the effects of large-scale intraplate events, and to apply those findings to the mitigation of similar earthquake hazards in mid-America.
