%X This paper includes a bibliographic review with the description of the various aspects about the (Ms = 8.1) Michoacan, Mexico earthquake, which comprised of three events. The main shock of the September 19, 1985 earthquake occurred on Thursday at 7h. 17m. 46.6s. local time in Mexico City, and had (Ms = 8.1). The focus of the event was a depth of approximately 18 km. A second shock occurred on Friday evening 21 September at 7h. 38m. p.m. local time. The last aftershock occurred on 30 April of 1986 (Ms = 7.0). A prior event occurred to the September 1985 earthquake, occurred on 28 May, 1985 (mb = 5.2) and is described too. This event, was a terrible natural disaster for that country, at least 9,500 people were killed, about 30,000 were injured, more that 100,000 were left homeless and severe damage occurred in many parts of Mexico City and several states of central Mexico. According to some sources, It is estimated that the earthquake seriously affected an area of approximately 825,000 square kilometers. This paper describes a summary of the global tectonic setting, genesis and location of the epicenter, an interpretation of the source mechanism and a analyses at these results from some stations that recorded this earthquake and at the same time, a comparison between the two largest earthquake of 1985. Moreover, this paper describes the principal damage resulting and a description of effects from tsunami produced from earthquake. The 1985 Mexico earthquake occurred as a result of slipping in the subduction process between the Cocos and American plates. This was a shallow interplate thrust type event which occurred in the intersection of the Orozco fracture with the Middle American trench.
