Tremor in Mexico today, Sunday April 20: Exact time, epicenter place and where was the last earthquake of the SSN | CDMX Microsism | Oaxaca | nnda nnrt | MAG

Mexico It is characterized by being one of the countries in the world to present a constant seismic and volcanic activity. According to him National Seismological Service (SSN) with support of United States Geological Service (USGS)the Mexican territory tends to experience strong telluric movements worldwide due to its geographical location in the fire belt.

This explains the reason for why Mexico is particularly susceptible to earthquakes due to its location on the edge of five tectonic plates: that of the Caribbean, that of the Pacific, that of North America, that of Rivera and that of Cocos. The interaction of these plates causes the country to experience an average of four daily tremors.

In history, the strongest earthquakes in Mexico have occurred in September with magnitudes greater than 7 degrees on the Richter scale.

According to Cenapredchronologically correspond to the events recorded on September 19 and 20, 1985 on the coast of Michoacán and Guerrero (magnitudes 8.1 and 7.6, respectively).

On September 7 and 19, 2017 in central Mexico and Gulf of Tehuantepec (magnitudes 8.2 and 7.1, respectively); and September 7, 2021 on the coast of Guerrero (magnitude 7.1).

Much of these are mainly remembered for the human and losses human damages that caused.

In that context, I share you The official report of the last earthquakes detected by the SSN in the territory of Mexico this Sunday, April 20 from states that record more seismic frequency as Oaxaca, Guerrero, Chiapas, Michoacán, Jalisco, Baja California, Colima, among others.

We will also emphasize the so -called “Mycrosism”, Taslores of low intensity and that usually go unnoticed by alert systems, which usually register in the Mexico City (CDMX).

Check the recommendations offered by the Cenapred (National Disaster Prevention Center) to be prepared before, during and after a strong earthquake and monitoring of the seismic alert system.

In this map of Cenapred We can appreciate the states of Mexico that they are exposed to strong tremors in three levels of risk of seismicity: low, medium and high.

States lists with more seismic records in Mexico:

• Mexico City
• Baja California Sur
• Baja California Norte
• Sonora
• Puebla
• Morelos
• Tlaxcala
• Veracruz
• Guanajuato
• Aguascalientes
• Zacatecas
• Sinaloa
• Quintana Roo
• Yucatan
• Campeche
• Hidalgo
• Querétaro
• San Luis Potosí
• Tamaulipas
• Nuevo León
• Coahuila
• Durango
• Chihuahua

According to the National Seismological Service of Mexico (SSN), between 1900 and 2022, 260,634 earthquakes have been registered in the region, 86 of them with magnitudes greater than 7.0. Only in 2022, 29,872 tremors were reported.

If in case you felt a strong earthquake, especially in Mexico City (CDMX) And you did not receive any alert message on your mobile this can be the so -called “mycrosism”, low intensity tremors that do not exceed the magnitudes of 3 degrees and that are almost imperceptible on Earth. Remember that Mexican seismic alert system (SASMEX) It is only activated in the following scenarios:

• 1) when the magnitude of the earthquake is greater than 5 degrees and occurs at 170 kilometers
• 2) When the magnitude is 6 degrees and the epicenter is located more than 350 km from the capital
• 3) When the magnitude exceeds 5.5 degrees less than 350 km.

“We are looking for more slow earthquakes, such as May and December 2023 in the Barranca del Muerto and Mixcoac failures, perhaps occurred in other further failures to the north and that are related to recent microsism,” he explained Victor Manuel Cruz Atienzaseismologist at UNAM, for the EFE agency.

I share a useful list of good actions that you must perform in order to face a strong earthquake in Mexico or any other country in the world. Put into practice the following security recommendations that I will show you below:

Before the earthquake in Mexico

• Constantly check your home infrastructure.
• Install security locks, cabinets and shelves.
• Save the most fragile objects in safe places.
• Always have a first aid kit.
• Find an optimal meeting point where there is enough security for your family.
• Educate your relatives so that they can close light, gas and water keys.
• Make a list of emergency numbers to contact doctors, police, civil protection, among others.

During the earthquake or earthquake in Mexico

• Get away from the windows, mirrors and shear objects that can fall to the ground.
• Find a shelter under a resistant table or, too, you can put under the frame frame.
• Give yourself your head and neck with your arm.
• Avoid using the elevators and takes the stairs during the earthquake.
• Never run away from a building when the earthquake is in motion.

After the earthquake in Mexico

• Find medical help to serve people affected with serious injuries.
• Provide first aid and emotional support to the injured who need it.
• Do not use the mobile phone irresponsibly, so you will avoid overloading the lines.
• Check the structural damage of your home.
• Close the keys to avoid possible lights of light, water or gas.
• Do not turn on candles, matches or other element that can cause a fire.
