The 1985 Mexico City earthquake struck in the early morning of 19 September at 07:17:50 (CST) with a moment magnitude of 8.0 and a maximal Mercalli intensity of IX (Violent). The event caused serious damage to the Greater Mexico City area and the deaths of at least 5,000 people. The sequence of events included a foreshock of magnitude 5.2 that occurred the prior May, the main shock on 19 September, and two large aftershocks.

They were located off the coast along the Middle America Trench, more than 350 kilometres (220 mi) away, but the city suffered major damage due to its large magnitude and the ancient lake bed on which Mexico City sits. The event caused between three and five billion USD in damage as 412 buildings collapsed and another 3,124 were seriously damaged in the city.
The 2003 Colima earthquake occurred on 21 January with a moment magnitude of 7.6 and a maximum Mercalli intensity of VIII (Severe).

The quake was felt in Guerrero, Michoacán, Mexico State, Mexico City and Puebla.
The 1932 Jalisco earthquakes began on June 3 at 10:36 UTC with a megathrust event that registered 8.1 on the moment magnitude scale. With a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale, at least 400 deaths were caused in Mexico and neighboring Guatemala. It was the first of a series of seismic events that affected parts of western Mexico during the month of June 1932, all reaching magnitude 7 or greater.
The 2012 Guerrero–Oaxaca earthquake struck southern Mexico with a moment magnitude of 7.4 at on Tuesday, 20 March. Its epicenter was near Ometepec, in the border between the states of Guerrero and Oaxaca. With a shallow focus of 20 km, the earthquake caused strong shaking over a large area along the Oaxaca–Guerrero border and the adjacent Pacific coastline. Significant tremors were felt in areas up to several hundred kilometers away, including Mexico City and also in Guatemala. Two people were killed and over 30,000 houses were damaged or destroyed.
The 1964 Guerrero earthquake occurred on July 6 at in Guerrero, Mexico. The magnitude of this earthquake was given as Ms 7.4, or ML 7.2.
The 1981 Playa Azul earthquake occurred on October 24, 1981, at 21:22 local time. It was located near Playa Azul, Michoacán, Mexico. The magnitude of the earthquake was 7.2, or 7.3. Three deaths were reported, two from Michoacán and one from Mexico City. Some buildings were damaged in both Michoacán and Mexico City. A small tsunami was registered in Acapulco with a maximum height of 9 cm.
The 1787 New Spain earthquake, also known as the San Sixto earthquake, occurred on 28 March at 11:30 local time. It caused a large tsunami that affected the coast of the Puebla Intendancy and the Oaxaca Intendancy in Southwestern New Spain. With an estimated magnitude of 8.6 on the moment magnitude scale, it was more powerful than any instrumentally recorded Mexican earthquake.
The 2017 Puebla earthquake struck at 13:14 CDT on 19 September 2017 with an estimated magnitude of 7.1 and strong shaking for about 20 seconds. Its epicenter was about 55 km (34 mi) south of the city of Puebla, Mexico. The earthquake caused damage in the Mexican states of Puebla and Morelos and in the Greater Mexico City area, including the collapse of more than 40 buildings. 370 people were killed by the earthquake and related building collapses, including 228 in Mexico City, and more than 6,000 were injured.
The 1957 Guerrero earthquake occurred on 28 July at 08:40 UTC. It had a magnitude of 7.6 and a maximum perceived intensity of VII on the Modified Mercalli intensity scale. Mexico City and Chilpancingo were particularly badly affected. It caused the deaths of between 54 and 160 people. A small tsunami was triggered but caused little damage.
On January 30, 1973, at 15:01 (UTC–6), a magnitude 7.6 earthquake struck 35.3 km (21.9 mi) beneath the Sierra Madre del Sur range in the Mexican states of Colima, Jalisco and Michoacán. On the Mercalli intensity scale, the earthquake reached a maximum intensity of X (Extreme), causing serious damage in the region. At least 56 people were killed and about 390 were injured. The event is commonly referred to as the Colima earthquake.
The 1920 Xalapa earthquake was the deadliest in Mexico's history prior to 1985—killing at least 648 people. It occurred on January 3 at 22:25 local time, during a period of political unrest in the country. Mudflows and landslides triggered by the shock destroyed buildings in rural towns across the states of Veracruz and Puebla, causing most of the deaths. The earthquake was attributed to a shallow fault in the Trans-Mexican Volcanic Belt. It measured moment magnitude 6.3–6.4 and had a hypocenter depth of <15 km (9.3 mi). The Mexican government took immediate action in the aftermath—providing assistance and establishing communication services. Severely damaged towns including Xalapa were rebuilt, while others had to be abandoned. Help to survivors also came from civil society groups, civilians, and the Catholic Church. The earthquake's aftershocks were studied by scientists to determine its seismological characteristics.
The 1979 Petatlán earthquake, also known as the IBERO earthquake occurred on March 14 at 05:07 local time in the Mexican state of Guerrero. The earthquake had a surface wave magnitude of Ms 7.6 or moment magnitude of Mw 7.4 and maximum Modified Mercalli intensity of VIII (Severe). The epicenter, onshore, was located 12 km south southeast of Vallecitos de Zaragoza.
A moment magnitude Mw 7.0 or 7.1 earthquake occurred near the city of Acapulco in the Guerrero state of Mexico at on 7 September with an estimated intensity of VIII (Severe) on the MMI scale. The earthquake killed 13 people and injured at least 23 others. At least 1.6 million people in Mexico were affected by the earthquake which resulted in localized severe damage. The earthquake occurred on the anniversary of the 2017 Chiapas earthquake which measured Mw 8.2. It was also the largest earthquake in Mexico since the 2020 Oaxaca earthquake.
On 19 September 2022, a moment magnitude 7.7 earthquake struck between the Mexican states of Michoacán and Colima at 13:05:06 local time. The earthquake had a depth of 16.9 km (10.5 mi), resulting in a maximum intensity of VIII (Severe) on the Modified Mercalli intensity scale. The USGS reported the epicentre was 37 km (23 mi) southeast of the town of Aquila. Two people were killed and at least 35 others were injured across several states. A magnitude 6.8 aftershock struck on 22 September, causing three more deaths.
