Given the intense seismic activity in Mexico, which is due to its location on the Ring of Fire, proper preparation becomes crucial. In particular, Mexico City faces various risks related to tremors, earthquakes and microseisms. He National Seismological Servicel plays an essential role in collecting and disseminating accurate information on earthquake movements. The SSN, as the authority responsible for collecting data on seismic activity in Mexico, provides updates on the most recent earthquakes that have occurred in the country.
Tremor in Mexico: latest reports from the SSN
The assessment of the magnitude of earthquakes in the country, carried out by the National Seismological Service (SSN) through a thorough analysis of isosist reports and maps, is considered an essential factor in the decisions made in the field of civil protection. . The information collected and shared by the SSN is crucial for both the authorities and the population, as it facilitates the application of appropriate preventive measures.
It is essential to follow safety guidelines to minimize possible consequences during seismic events, especially after the National Seismological Service (SSN) of Mexico identified a series of tremors with various intensities, ranging from mild to moderate. The relevance of providing adequate information to the community about seismic activity is highlighted.
What is the National Seismological Service (SSN)?
The National Seismological Service (SSN) is an entity specialized in the observation and analysis of the seismic activity of a country. Its work focuses on the detection and registration of telluric movements that occur in the region, using a network of strategically located measurement instruments.
These devices, known as seismographs, collect data on the magnitude, depth, epicenter and distribution of tremors. Using this information, the SSN generates detailed reports that help to better understand seismic activity and prevent possible risks, issuing early warnings in the event of relevant earthquakes.
In addition to monitoring and recording earthquakes, the National Seismological Service plays a crucial role in disseminating information on seismic activity through bulletins, reports and maps, offering authorities and the general public accurate and up-to-date data on telluric movements.
This information is essential for civil protection decision-making and helps people understand the risks associated with earthquakes, thus encouraging preparation and adoption of appropriate safety measures.
The importance of being ready for an earthquake
The importance of being prepared for earthquakes is fundamental, even when it is impossible to accurately predict when the next earthquake event will occur. Specialists emphasize the need to have an established evacuation plan, have emergency kits and know safe areas both inside and outside buildings.
Essential items such as water, non-perishable food, a battery-powered radio, flashlights, basic supplies of medications, and duplicates of relevant documents should be included in these emergency kits. In addition, the importance of educating all family members, including children, about the measures to follow before, during and after an earthquake is highlighted.
Safety measures during an earthquake
During an earthquake, it is crucial to remain calm and follow the “Stop, Cover and Hold On” protocol. It is essential to stay away from windows, mirrors, hanging objects and furniture that could fall. If you are inside a building, it is advisable to avoid leaving until the earthquake ends.
In outdoor areas, it is vital to stay away from buildings, trees, power poles and other objects prone to falling. If you are driving, it is safest to stop the vehicle in a clear area and stay inside until the shaking stops to avoid possible debris.
Basic explanation of earthquakes
An earthquake, also called an earthquake or tremor, is a natural event in which the Earth suddenly releases energy in the form of seismic waves. This energy release is usually the product of the fracture of rocks in the Earth's crust, caused by the prolonged accumulation of tension. When these rocks break, they emit seismic waves that expand from the point of rupture, generating vibrations on the Earth's surface.
- What is the origin of earthquakes?
Earthquakes can originate naturally, as a result of tectonic activity at tectonic plate boundaries, or they can be caused by human actions, such as the extraction of resources such as oil and gas, mining, or the injection of fluids into the subsurface. These events can have considerable impacts on inhabited areas, causing damage to structures, infrastructure and even human losses. For this reason, constant research and monitoring is carried out to better understand them and develop risk reduction strategies.
- How are earthquakes evaluated?
The magnitude of an earthquake can vary, from almost imperceptible movements to devastating earthquakes. The magnitude is measured using the Richter scale or the moment magnitude scale, relating it to the amount of energy released. On the other hand, intensity is evaluated using the Mercalli scale and is associated with the effects observed on the surface, such as damage to buildings and people's perception.
- Differences between earthquake, tremor and earthquake
The fundamental differences are found in the magnitude and intensity of the seismic movements. The term “earthquake” covers any type of earth movement, while “tremor” usually refers to seismic movements of smaller magnitude, and “earthquake” describes larger seismic events with more serious consequences. Exact designations may vary by geographic region and local conventions.
