And 2.9 magnitude earthquake took by surprise the Chilean city of Mina La Escondida. This Friday, March 17, the National Seismology Center (CSN) announced it.
According to preliminary information, the seismic activity began at 04:39 (local time), when the earth has moved 89.0 kilometers deep.
The CNS reported that the exact location of the epicenter It was at -24.027 degrees latitude and -68.855 degrees longitude, i.e. 34.0 kilometers northeast of the city.
Remember that before any earthquake only follow information from official sources, avoid falling into the trap of rumors or fake news.
after an earthquake, check your house to check for possible effects, only use your mobile phone in an emergency, do not saturate telephone linesdo not light matches or candles before make sure there are no gas leaks. It is important to mention that after an important telluric movement, replies can be filedit is therefore 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 safe areas home, school or workplace and set up a emergency backpack.
during a tremor keep calm and stay in a safe place, stay away from falling objects, do not use elevators, do not stay in the stairwell or doorway.
if you are drivingpark and stay clear of 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; And 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.
Chile is one of the countries with the greatest seismic activity on the planetthis is due to its geographical and geotectonic location, since it is in one of the areas with increased energy releasein the permanent convergence of “Nazca Plate” and “South American Plate”in the so-called subdiction zone.
Additionally, the country is located in the area known as Ring of the Pacific or Ring of Fireconsidered the region with the highest number of volcanoes and earthquakes on the planet.
This area brings together 75% of the volcanoes that exist in the world and includes more than 450 volcanic structures, not to mention that this is where they occur 90% of the world’s seismic activity and 81% of the strongest telluric movements of the planet.
Only in Chile took place 50% of the tsunamis of which there are records in the worldaccording to information from the Department of Emergency and Disaster Risk Management.
The Pacific Ring of Fire encompasses the entire Pacific Coast, starting from Chile, passing through Central America, Mexico, the United States, crossing the Aleutian Islands, later along the coasts of Russia, Japan, Taiwan and the Philippines, until reaching New Zealand.
Some volcanoes that are in the Pacific Ring of Fire and have produced large eruptions with significant damage globally are: Krakatoa In Indonesia, Mount Fuji In Japan, mont saint helene in the United States, the Chichon in Mexico and Nevado del Ruiz in Colombia, among others.
Whenever an earthquake or a major eruption occurs in this region, the fear arises that the Pacific Ring of Fire is “activated” generating more natural disasters, however, It is not possiblesince each earthquake or volcanic activity is mostly independent of each other, i.e. they are not directly related.
Since 1570, there have been a hundred earthquakes of great force in Chile, nearly thirty of which were of magnitude greater than 8.
According to the Department of Emergency and Disaster Risk Management, it occurs on average an earthquake of magnitude greater than 8 every decade. These are some of the largest earthquakes recorded in Chile’s history.
The strongest earthquake in history
On the afternoon of May 22, 1960, a the most tremors ever recorded, of magnitude 9.5, had its epicenter in the city of Traiguén, in the province of Malleco. However, it is known as “Valdivia Earthquake” because that’s where the most damage was.
Seismic activity also caused a tsunami with waves up to 10 meters high which devastated much 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, causing several deaths and extensive damage in its wake.
The official death toll is not accurate, just we know that there were more than 2,000 victims.
The last great earthquake
The last major earthquake to hit Chile was the one called “27F” which occurred on February 27, 2010, the second strongest earthquake in its history.
With 8.8 magnitudethe seismic activity had as its epicenter the coasts of the Maule region and surprised the population at dawn.
Just like in 1960, about half an hour after the earthquake, a tsunami hit the country, mainly in the Maule and Biobío regions. Outside Chile, the tsunami reached Peru, Ecuador, Colombia and Costa Rica, without major damage.
after the earthquake more than 500 people died and there were around 50 people missing.
deadliest earthquake
On the night of January 24, 1939, a the deadliest earthquake in the history of Chile. An earthquake of magnitude 8.3 it was perceived from Valparaíso and as far as Temuco, however, it was in Concepción and Chillán where the most damage was concentrated.
This telluric movement was called the Chillán earthquake because it caused the most destruction there, just to say that more than half of its buildings have collapsed.
As a result of the tremor, electricity, telephone and telegraph services were interrupted, there was no transport, the railway station was abandoned and the disaster caused food and water shortages .
The 1939 Chillán earthquake is Chile’s deadliest tragedy. The official death toll was 24,000, but some estimate it was closer to 30,000, although only 5,685 have been identified.
Other earthquakes
In addition to the aforementioned earthquakes, there have been other significant ones in the history of Chile.
For example, there was two other telluric movements of magnitude greater than 8.5however, it happened over 100 years ago -not to mention the shocks already mentioned-, according to the records of the CSN.
The early morning of July 8, 1730 felt an 8.7 magnitude earthquake in Valparaíso that killed around 3,000 people. Another earthquake, this time 8.8 magnitude, was seen in Arica the night of September 16, 1615, which surprisingly, no casualties.
On the other hand, there two other earthquakes that left a death toll of more than 2,000: on the night of May 9, 1877, in Iquique, a an earthquake of magnitude 8.5; and that of the morning of February 8, 1570, which had a magnitude of 8.3.
