Taking into account that we are in an active plate boundary, the occurrence of earthquakes is “normal”, with the southeast of the Peninsula being the most affected area, especially the provinces of Granada, Malaga and Almeria.

What are the areas with the highest seismic risk and why?

Chiapas, Guerrero, Oaxaca, Michoacán, Colima and Jalisco are the states with the highest seismicity in the Mexican Republic due to the interaction of the Cocos and Rivera oceanic plates that subduct with those of North America and the Caribbean on the Pacific coast in front of these states, also by this very action are…

What are the seismic risk zones?

Earthquakes in Argentina are produced by the contact of the Nazca Plate with the South American Plate. They occur more frequently in the provinces located to the west of our region: Mendoza, San Juan, Catamarca, La Rioja, Salta and Jujuy, but no part of the country is exempt from this phenomenon.

What areas of Spain have a higher seismic risk?

The most destructive: Between Andalusia and the Valencian Community

Despite the peculiarities of the Canary Islands, the most active seismic zone in Spain is the peninsula. It is the southern part, from Andalusia, through Murcia and to the south of the Valencian Community.

What are the areas of Spain most affected by geological risks?

Around 2,500 earthquakes occur annually in Spain, but only two per month are felt by the population. The highest rate of danger is in the south and southeast of the Peninsula, around Granada, the southern area of ​​the province of Alicante and those of Almería and Murcia.

Specifically, this territory is crossed by two main faults: the Granada fault, which is actually a set of small faults, and the Alhama de Murcia fault.

What area of ​​the Iberian Peninsula has the greatest risk of suffering an earthquake?

The area with the greatest seismic activity in the Iberian Peninsula is the southern area, both in the subsoil of the emerged territory and under the sea.

What is the most seismic zone in the world?

Of all the earthquakes recorded in the world, 90% occur in a single region: the Pacific Ring of Fire. It is the largest seismic and volcanically active zone in the world.

What are the areas where the magnitude of earthquakes is greater?

The peninsular southeast, the area of ​​greatest risk.

Why is the south of the Iberian Peninsula a region of seismic risk?

The entire south of the peninsula, the Alboran Sea and the north of Morocco are in a seismic zone that corresponds to the contact between the African and Eurasian plates. The convergence between these two plates began about 40 million years ago, and continues today at a rate of between 4 and 10 millimeters per year.

Where there are no earthquakes?

This is the case, for example, in Brazil: being so far from plate boundaries (see map), seismicity is very low. The same can be said of Korea, Australia or the central part of Canada, among others.

Where is there more chance of an earthquake occurring in Granada or Lugo?

Experts insist that “if you want to know where the shocks will come from, you have to look” at Granada, since Andalusia is the area where there is the most probability of a large earthquake. Spain is at risk of suffering “the great earthquake”.

What are the tectonic plates of Spain?

In this global geotectonic framework, the peninsular lands and the Balearic Islands are located on the Eurasian plate, while the Canary Islands (whose origin is volcanic), Ceuta and Melilla are located on the African plate.

According to the National Geographic Institute, the largest earthquake recorded in the Iberian Peninsula took place in Cabo de San Vicente on November 1, 1755. With a magnitude of 8.5, it caused 1,500 deaths by producing a tsunami almost 15 meters high. that affected Western Europe and North Africa.

What states have a low seismic zone?

The Low Seismic Zone: It is located in the states of Coahuila, Nuevo León, Tamaulipas, Campeche, Yucatán, Quintana Roo, as well as a part of the states of Chihuahua, Durango, Zacatecas, San Luis Potosí, in this area there are no records that large tremors ever occurred and no earthquakes have been reported either…

Which continent has low seismicity?

Europe is almost exempt from these meteorological phenomena due to factors such as the temperature of the ocean, the low humidity of the atmosphere and the lack of clashes of hot and cold air currents in the region.

Where are the tremors felt less in CDMX?

Among the areas of lower intensity are: Ciudad Universitaria, Ajusco, Pedregal de San Francisco in Coyoacán, Lomas de Chapultepec, and sections one, two and three of Polanco in the Miguel Hidalgo delegation.

It extends from the southern coast of Portugal and North Africa, through the Mediterranean Sea area, Asia Minor to the Himalayas, with ramifications to Insulindia, Tibet and China. 21% of the seismic movements are recorded in this area.

What is a seismicity map?

A seismicity study is one that shows a map with the epicenters and the number of earthquakes that occur in a given period.

How is its mode of propagation of earthquakes?

The propagation of waves produced by earthquakes is determined by the mechanics of elastic media and, therefore, their speeds depend on the elastic characteristics of the medium, whose distribution can be studied by observing the travel times and amplitudes of these waves. .

How and why do earthquakes occur?

An earthquake is the sudden movement of the Earth (with capital letters, since we refer to the planet), caused by the sudden release of energy accumulated over a long time.
