How much should the survival backpack weigh?

The ideal weight should not exceed 25% of the body weight of the person carrying it, ensuring a quick and agile evacuation.

Can an earthquake be predicted?

Currently, it is impossible to determine, as the Earth itself presents a wide dynamic regarding its movements, considering that it is not only about predicting when it will shake, but also being able to determine the intensity, magnitude, depth, and other important factors.

• CAN EARTHQUAKES BE PREDICTED?

To date, there is no technique that allows predicting earthquakes. Not even countries like the United States and Japan, whose technology is very advanced, have been able to develop a predictive technique for tremors.

• CAN ALL EARTHQUAKES GENERATE TSUNAMIS?
• A Tsunami is waves several meters high produced by an earthquake whose hypocenter occurs under the ocean. These earthquakes cause the seabed to move vertically, which generates a violent displacement of the volume of water above it.

• HOW TO DIFFERENTIATE A TREMOR FROM AN EARTHQUAKE?  
• Both are movements of the Earth, but we usually call “earthquake” those of greater magnitude and destructive impact, while “tremor” is used for lighter seismic events.

• Stay calm and go to the previously selected lower-risk places. Do not use elevators
• Stay away from objects that may fall and from windows
• If possible, turn off the gas valves and lower the main electricity switch

• HOW TO DIFFERENTIATE A TREMOR FROM AN EARTHQUAKE?
• The terms “tremor” and “earthquake” are often used interchangeably, but generally, the difference lies in their magnitude, perceived intensity, and reach.

• • Tremor : Refers to seismic movements of lesser intensity. Usually, it is used to describe low magnitude earth tremors that do not cause significant damage to structures or people. They are perceptible, but their impact is mild.

• • Earthquake : Refers to a seismic event of greater magnitude. Earthquakes are significant seismic tremors that can cause severe damage to buildings, infrastructure, and, in the most severe cases, cause personal injuries and even loss of life. They have considerable magnitude and are often accompanied by aftershocks.

As of 08:00 hours on September 14, 2026, 2,540 aftershocks of the M 7.4 earthquake that occurred in Ciudad Hidalgo, Chiapas on July 17, 2026, have been recorded, the largest with a magnitude of M 6.5.

Earthquake 15 km southeast of Matías Romero, Oaxaca

• Magnitude: 4.0
• Date: 14/09/26
• Time: 08:11:57
• Latitude: 16.77
• Longitude: -94.95
• Depth: 96 km

• How to know if an earthquake is strong? 

There are two ways: 

– Magnitude, measured on the Richter scale, indicates the energy released. 

– Intensity, measured on the Mercalli scale, measures the impact on people and structures.

• WHAT IS THE LARGEST MAGNITUDE EARTHQUAKE THAT SHOOK MEXICO CITY?
• On September 19, 1985, Mexico City experienced a devastating earthquake of 8.1 magnitude, with its epicenter on the Pacific coast. 
• It is estimated that at least 10,000 people lost their lives, affecting and collapsing thousands of housing, commercial, and public service structures.

• WHAT IS AN EARTHQUAKE?
• An earthquake is a sudden rupture of rocks inside the Earth. This sudden release of energy propagates in the form of waves that cause ground movement.

• HOW LONG DOES AN EARTHQUAKE LAST AND WHY DOES THE SSN NOT REPORT THIS DATA?
• When we talk about the duration of an earthquake, we can refer to several different concepts: One is the duration of the movement perceived by humans, another is the duration of the instrumental record (which can be several minutes), and another is the time the fault movement that caused the earthquake lasted (which can be a few seconds).

• WHAT IS THE DIFFERENCE BETWEEN THE MAGNITUDE AND INTENSITY OF AN EARTHQUAKE?
• They are scales to measure the size or impact of a tremor. The magnitude scale is obtained numerically from records obtained by seismographs and is related to the size and energy released during a tremor. The intensity scale is assigned based on the damage or effects caused to people and their constructions.

• WHY DO SO MANY EARTHQUAKES OCCUR IN MEXICO?
• In the context of Plate Tectonics, Mexico is located in the so-called Ring of Fire, where a large part of the seismic movements worldwide are recorded. The country is located on the North American Plate, bordered on its southern and western portion by the Cocos, Rivera, and Pacific plates.

• Mexico is one of the countries in the world with the highest seismic activity, as according to statistics, more than 90 earthquakes per year with a magnitude greater than 4 on the Richter scale are recorded, which is equivalent to 60% of all seismic movements recorded worldwide.

What was the magnitude and where was the last tremor in Mexico? See live here the reports from the National Seismological Service (SSN) about earthquakes in the country.
