Tremor in Chile: 3.1 magnitude earthquake in Calama

A magnitude 3.1 tremor felt in the Chilean city of Calamaaccording to preliminary data from the National Seismological Center (CSN).

Updated information indicates that the telluric movement began at 06:04 (local time) this Friday, January 13.

The epicenter of the earthquake was 66.0 kilometers northeast of the cityat -21.959 degrees of latitude and -68.601 degrees of longitude and had a depth of 113.0 kilometers.

Remember that before any tremor follow information only from official sources, avoid falling for rumors or false news. All the information on the country’s seismic activity can be consulted on the official CSN website at this link.

After an earthquake, check your home In search of possible damage, use your cell phone only in an emergency, avoid saturating telephone linesdo not light matches or candles until make sure there is no gas leak. It is important to mention that after a major telluric movement, replicas can be filedso it is important to be vigilant.

An earthquake can happen at any time, so it is important to be prepared with the following measures: prepare a civil protection plan, organize evacuation drills, find safety zones at home, school or workplace and set up a emergency backpack.

What to do before, during and after an earthquake (Infobae/Jovani Pérez).

during a tremor keep calm and stay in a safe place, stay away from objects that could fall, do not use the elevators, do not stay in the stairwell, or in the doorway.

if you are in a carpark and stay away from buildings, trees and poles; if you are on the coast, leave the beach and take refuge in high areas, before the possibility of a tsunami; Y if you are in a wheelchair and you cannot move to a safe place, stop the wheels and protect your head and neck with your arms.

Pacific Ring of Fire

Chile is one of the countries with the most seismic activity in the worldthis is due to its geographical and geotectonic location, since it is within one of the areas with increased energy releasein the permanent convergence of the “Nazca Plate” and the “South American Plate”in the so-called subdiction zone.

In addition, the country is located in the area known as Pacific Ring or Ring of Fireconsidered the region with the largest number of volcanoes and tremors on the planet.

This area gathers 75% of the volcanoes that exist in the world and includes more than 450 volcanic structures, in addition, it is where they occur 90% of the world’s seismic activity and 81% of the strongest earthquakes of the planet.

Only in Chile have occurred 50% of the tsunamis of which there are records in the worldaccording to information from the Department of Risk Management in Emergencies and Disasters.

Pacific Ring of Fire encompasses the entire Pacific coast, starting in Chile, passing through Central America, Mexico, the United States, touring the Aleutian Islands, later down the coasts of Russia, Japan, Taiwan and the Philippines, until reaching New Zealand.

Some volcanoes that are in the Pacific Ring of Fire and that have produced important eruptions with extensive damage on a global scale are: Krakatoa In Indonesia, Mount Fuji in Japan, mount st helen in the United States, the Bump in Mexico and the Nevado del Ruiz in Colombia, among others.

Every time a relevant earthquake or eruption occurs in this region, the fear arises that the Pacific Ring of Fire is “activated” causing more natural disasters, however, this is not possiblesince each earthquake or volcanic activity is mostly independent of each other, that is, they have no direct relationship.

The strongest earthquakes in Chile

Since 1570, about a hundred strong earthquakes have occurred in Chile, of which almost thirty were of magnitude greater than 8.

According to the Department of Risk Management in Emergencies and Disasters, on average, it occurs an earthquake of magnitude above 8 every 10 years. These are some of the most relevant tremors recorded in the history of Chile.

The strongest earthquake in history

On the afternoon of May 22, 1960, a the largest tremor on record, with magnitude 9.5, had as its epicenter the city of Traiguén, in the province of Malleco. However, it is known as the “Valdivia earthquake” because it was where there was more damage.

The telluric movement also caused a tsunami with waves up to 10 meters high that devastated a good part of the south of the country. The tsunami suffered beyond Chile, reaching Asia, in Japan, for example, it was hit by waves six meters high, leaving several deaths and significant damage in its wake.

The official death toll is not precise, just it is known that there were more than 2 thousand victims.

The last great earthquake

The last great tremor that shook Chile was the one known as “27F” which occurred on February 27, 2010, the second strongest earthquake in its history.

With 8.8 of magnitudethe seismic activity had as its epicenter the coasts of the Maule region and surprised the population during dawn.

Just like in 1960, less than an hour after the quake, a tsunami hit the country, mainly in the Maule and Biobío regions. Outside of Chile, the tsunami reached Peru, Ecuador, Colombia and Costa Rica, without major damage.

as a result of the earthquake more than 500 people died and there were around fifty people missing.

deadliest earthquake

On the night of January 24, 1939, a the deadliest earthquake in Chilean history. An 8.3 magnitude quake it was perceived from Valparaíso and up to Temuco, however, it was in Concepción and Chillán where the most damage was concentrated.

This seismic activity was known as the Chillán earthquake because it was right there where it caused the most destruction, just to say that more than half of its buildings collapsed.

As a result of the tremor, electricity, telephone and telegraph services were interrupted, there was no transportation, the railway station was left on the ground and the disaster caused shortages of food and water.

The 1939 Chillán earthquake is the tragedy that has claimed the most fatalities in Chile. The official number of deaths was 24,000, but some estimate that it was close to 30,000, although only 5,685 were identified.

Other earthquakes

In addition to the aforementioned earthquakes, there have been other important ones in the history of Chile.

For example, there have been two other telluric activities with magnitude greater than 8.5however, these have happened more than 100 years ago -not counting the aforementioned earthquakes-, according to CSN records.

The early morning of July 8, 1730 felt an 8.7-magnitude earthquake in Valparaíso that left around 3,000 victims. Another earthquake, this time of 8.8 of magnitude, was perceived in Arica the night of September 16, 1615, which surprisingly he did not leave dead.

On the other hand, there two more tremors that left a balance of more than 2 thousand deaths: on the night of May 9, 1877, in Iquique, a a magnitude 8.5 earthquake; and that of the morning of February 8, 1570, which had a magnitude of 8.3.
