A 4.7 magnitude earthquake took by surprise the city of Calama This Sunday, April 28, this was announced by the National Seismological Center (CSN).
According to the official information published so far, the earthquake began at 4:20 p.m. (local time), when the earth moved to a depth of 78.0 kilometers.
The CNS reported that the exact location of the epicenter was -21.958 degrees latitude and -68.718 degrees longitude, that is, 61.0 kilometers north of the town.
Remember that in the event of any earthquake, only information from official sourcesavoid falling into rumors or fake news.
After an earthquake, check your home for possible damage, use your cell phone only in case of emergency, avoid saturating telephone lines, do not light matches or candles until you are sure there is no gas leak. It is important to mention that after a major earthquake, aftershocks may occur, so it is important to be alert.
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 prepare a backpack of emergency.
During an earthquake, stay calm and find a safe place, stay away from objects that could fall, do not use elevators, or stay in a stairwell or in a door frame.
If you are in a car, park and stand away from buildings, trees and poles; If you are on the coast, leave the beach and take refuge in high areas, given the possibility of a tsunami; And if you are in a wheelchair and cannot move to a safe place, brake the wheels and protect your head and neck with your arms.
Since 1570, About a hundred earthquakes of great force have occurred in Chile, of which almost thirty were of magnitude greater than 8.
According to the Department of Emergency and Disaster Risk Management, on average, an earthquake above magnitude 8 occurs every 10 years. These are some of the most relevant earthquakes recorded in the history of Chile.
The strongest earthquake in history
On the afternoon of May 22, 1960, the strongest earthquake on record occurred, with magnitude 9.5, with the city of Traiguén, in the province of Malleco, as its epicenter. However, it is known as the “Valdivia earthquake” because it was where there was the most damage.
The earthquake also caused a tsunami with waves up to 10 meters high that devastated much of the south of the country. The tsunami was felt beyond Chile, reaching Asia, in Japan, for example, it was hit with waves six meters high, leaving several dead and significant damage in its wake.
The official death toll is not precise, it is only known that there were more than 2 thousand victims.
The last great earthquake
The last major earthquake that hit Chile was the one known as “27F” which occurred on February 27, 2010, the second strongest earthquake in its history.
With a magnitude of 8.8, the seismic activity had its epicenter on the coasts of the Maule region and surprised the population during the early hours of the morning.
As in 1960, less than an hour after the earthquake, a tsunami hit the country, mainly in the regions of Maule and Biobío. 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 around fifty were missing.
The deadliest earthquake
On the night of January 24, 1939, it occurred the deadliest earthquake in the history of Chile. An 8.3 magnitude tremor was felt from Valparaíso and 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 saying that more than half of its buildings fell.
As a result of the earthquake, electricity, telephone and telegraph services were interrupted, there was no transportation, the railway station was left in the ground and the disaster caused a lack of food and water.
The Chillán earthquake of 1939 is the tragedy that has claimed the most fatalities in Chile. The official death toll 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 earthquakes mentioned, there have been other important ones in the history of Chile.
For example, two other telluric activities with magnitude greater than 8.5 have been recorded, however, these have occurred more than 100 years ago -not counting the tremors already mentioned-, according to CSN records.
In the early morning of July 8, 1730, an 8.7 magnitude earthquake was felt in Valparaíso that left around 3,000 dead. Another earthquake, this time of 8.8 magnitude, was recorded in Arica on the night of September 16, 1615, which surprisingly left no victims.
On the other hand, there are two more earthquakes that left more than 2 thousand deaths: on the night of May 9, 1877, in Iquique, an earthquake of magnitude 8.5 was recorded; and that of the morning of February 8, 1570, which had a magnitude of 8.3.
