[12] The government itself realized that it could not handle the crisis alone through already-established institutions and decided to open the process up to "opposition groups". [4] This subduction zone outside the Michoacán gap was the source of 42 earthquakes of magnitude 7.8 or stronger in the 20th century prior to the 1985 event.  |  Around 240 people have been killed and 2,000 injured [4] Prior to the event, estimates about ground movement on the lakebed were generally accepted and a number of buildings were built on these estimates. [5], To better help deal with major disasters, the Civil Protection Committee was created. At the top was a helipad. On the day of the quake, the Metro stopped service and completely shut down for fear of electrocution. The magazine Proceso reported that by the time rescue workers reached the building, the owners were already in a hurry to demolish it, without trying to rescue or recover the workers trapped inside. More than 10,000 people were killed, 30,000 were injured, and large parts of the city were destroyed. However, the codes were not designed for seismic activity of the intensity experienced in 1985. [4][15], In the port of Lázaro Cárdenas, near the epicenter, the 19 September event registered as IX on the Modified Mercalli intensity scale; in parts of Mexico City, it registered the same, even at a distance of about 400 km (249 mi) away. [17], Several notable buildings were relatively untouched by the quake. A 20-story tower, Tower Four, doubled over at the third floor and fell south onto a fourteen-story building. It had its own cabaret, gourmet restaurant and a small but luxurious cinema with wide reclining armchairs.

Most of the beds that it lost were dedicated to tertiary, high-technology care. The 1985 Mexico City Earthquake On the morning of September 19, 1985, an 8.1-magnitude earthquake hit the western states of Mexico and including Mexico City. Mexico City residents re-lived a nightmare after a 7.1-magnitude earthquake killed hundreds and caused widespread destruction on Tuesday, the same day that a huge tremor in 1985 killed thousands. Most of the damage occurred in secondary and tertiary hospitals. It originally was called San Pablo Hospital but its name was changed to Juárez Hospital in 1872. [4], On the bed of the historic lake, the prevailing silt and volcanic clay sediments amplify seismic shaking. Official figures for the number of fatalities vary between 9,500 and 35,000. [22] The infants were found seven days after the initial event and came to be known as the "Miracle Babies" or the "Miracle of Hospital Juárez", having survived without nourishment, water, warmth or human contact during that time. The event caused serious damage to the Greater Mexico City area and the deaths of at least 5,000 people. These babies were pulled out of the wreckage mostly unscathed but lost their mothers. The deal generally worked; movements like CUD moderated their stances and agencies like SEDUE and PRHP made progress in rebuilding housing, regardless of political affiliation. Partly because of inadequate building codes, the death toll reached upward of 20,000 people. [20] Damage was localized to the center parts of the city, leaving much of the residential outer rim unscathed, but the damage in the affected area was extensive. This included the 700 beds lost with the complete collapse of Juárez Hospital and the gynecology-obstetrics tower of the General Hospital of Mexico. [23], The main reason that the figures have been disputed is the government's response to the tragedy. Much of the community organizing focused on helping those left homeless by the earthquake. Because of multiple breaks in the fault line, the event was of long duration. [42], The severe damage in so many buildings, including in many public works construction projects to house the rapidly growing population of Mexico City, was blamed on lax enforcement of building codes. [23][35], Buildings A1, B2 and C3 of the Multifamiliar Juárez complex partially collapsed with a total of nine structures eventually being demolished.[23][35]. [12] Consequently, most of the populace believes that the true numbers have never been revealed. Many of these patients were very ill. 1,900 patients were successfully moved from here, without any deaths, in just four hours. The earthquake occurred in the Pacific Ocean, off the coast of the Mexican state of Michoacán, a distance of more than 350 km (217 mi) from the city, in the Cocos Plate subduction zone, specifically in a section of the fault line known as the Michoacán seismic gap. Although there was severe damage in the coastal regions, the real disaster happened 220 miles away in Mexico City. [46][47], Despite warnings and predictions, in 2005, an estimated 32 million people live in the high-risk lakebed area. The damage was concentrated in a 25 km2 area of Mexico City, 350 km from the epicenter. [19], One of the most visible government institutions to fall in the event was the tower of Hospital Juárez, one of the oldest hospital institutions in Mexico. President de la Madrid refused to cut foreign debt payments to use the money to help with the recovery effort. One interesting characteristic was that many buildings had their upper floors collapse, leaving the lower floors relatively undamaged. Of a population of 18 million, an estimated 10,000 people were killed, and 50,000 were injured.
