A numerical hydrodynamic model was applied to Zihuatanejo Bay on the Mexican Coast of the Pacific Ocean to study the heights and arrival times of tsunamis produced by hypothetical 7.0 and 8.0 Mw magnitude earthquakes with epicenter in the Cocos Plate, at 16.9718°N–101.973°W, as well as the flooding of Zihuatanejo Town by the tsunamis. The travel times of the tsunamis to Zihuatanejo Coast are between 18 and 19 min, maximum sea surface elevations of 1 and 10 m at the coast are estimated following a 7.0 and 8.0 Mw earthquake respectively with a tsunami inland penetration up to 400 m in the second case affecting restaurants, hotels, banks, schools, businesses, museums, and even the municipal market of the town. Therefore, a densely populated area would be affected by a tsunami triggered by an 8.0 Mw earthquake.

墨西哥太平洋海岸芝华塔尼欧地区海啸爆发的模型研究

将数值流体动力学模型应用于太平洋墨西哥海岸的芝华塔尼欧湾，研究了假想的7.0和8.0 Mw级地震在Cocos板块震中于16.9718°N–101.973°W时产生的海啸的高度和到达时间以及海啸对Zihuatanejo镇造成的洪灾。海啸到芝华塔尼欧海岸的旅行时间在18到19分钟之间，在分别发生7.0和8.0兆瓦地震以及第二次海啸向内陆渗透达400 m之后，估计该海岸的最大海面海拔分别为1和10 m该案影响到饭店，旅馆，银行，学校，企业，博物馆，甚至镇上的市政市场。因此，人口稠密的地区将受到8.0 Mw地震引发的海啸的影响。
