1967年12月10日印度西海岸发生著名的烈度为8—9度的柯依纳地震(M=6.3)后至今已有20年。这次地震破坏了柯依纳城和柯依纳拦河大坝。这次地震的特点是它发生在古地台内即相当稳定的地壳构造单元内。按现在的看法,这里发生类似强烈的地震是不可能的,但历史上这里曾不至一次发生过类似震级或更大的地震,其中多数地震伴随有大规模的地表形变,这在世界上地震最活跃的地区也是少见,这就促使人们以新的观点来对待印度次大陆西部的地震活动性问题。
It has been 20 years since the Kojuna earthquake (M = 6.3), which took place on the west coast of India on December 10, 1967, with a magnitude of 8-9 degrees. The earthquake destroyed the Ke Yi Na City and Kojina dam. The earthquake is characterized by the occurrence of crustal tectonic units in the Paleogene, which is quite stable. As of now, it is not possible to have a similar strong earthquake here, but there have been no earthquakes of similar magnitudes or larger once in history, with most of the earthquakes accompanied by large-scale surface deformations, The most active areas are also rare, prompting a new perspective on the seismicity of the western subcontinent.
