An earthquake of magnitude 4.7 happened this Friday, October 28 in the city of Ica, in the province of Ica, in the department of Ica, according to the latest information from the National Seismological Center (Censis) of the Geophysical Institute of Peru (IGP).
According to reports obtained through the National Seismic Network, the movement began at 22:26:22 (local time) and originated 100 kilometers southwest of Ica.
The earthquake had a depth of 15 km. an intensity of III; as well as a latitude and longitude of -14.62 and -76.45 degrees.
Due to its magnitude, his alert range was yellow.
The green color range is used for earthquakes of magnitudes less than 4.4; yellow is assigned to movements whose magnitude oscillates between 4.5 to 6.0; while the red color designates earthquakes greater than 6.1.
As to The intensitythe scales indicate the following:
I: it is a movement “not felt” that does not represent “no harm”.
II-III: it is a movement “weak” that does not represent “no harm”.
IV: It is a movement “light” that does not represent “no harm”.
V: it is a movement “moderate” which represents “very little damage”.
VI: It is a movement “strong” which represents “little damage”.
VII: It is a movement “very strong” which implies a “moderate damage”.
VIII: it is a movement “severe” which implies a “moderate or high damage”.
IX: It is a movement “violent” which implies “a lot of damage”.
X+: It is a movement “extreme” causing “substantial damage”.
The CENSIS of the GPI obtains its data from the National Seismic Networkformed and integrated by a series of speed, acceleration and displacement sensors distributed throughout the country.
What is the Pacific Ring of Fire
Peru is located in the area known as the Pacific Ring of Fire.a region that concentrates 75% of the volcanoes that exist in the world and where approximately 80% of the strongest earthquakes of the world.
The so-called Pacific Ring of Fire is made up of the mountainous area of western Argentina, Chile, Peru, Ecuador, Colombia, Panama, Costa Rica, Nicaragua, El Salvador, Honduras, Guatemala, Mexico, the United States and Canada, to later double at the height of the Aleutian Islands and down the coasts and islands of Russia, Japan Taiwan, the Philippines, Indonesia, Malaysia, East Timor, Brunei, Singapore, Papua New Guinea, Solomon Islands, Tonga, Tuvalu and New Zealand.
In the case of Peru, the country is in the South American tectonic plate colliding head-on with the Nazca plate, being in friction, they generate tension, which is discharged in the form of earthquakes; In addition, the region presents constant volcanic activity.
The Ring of Fire extends over 40 thousand kilometers and has the shape of a horseshoe, in addition, within this line there are 452 volcanoes and is home to most of the so-called “supervolcanoes”, whose eruptions are VEI-8 levels, classified as catastrophic.
Strong earthquakes in Peru
The South American nation has had to face various seismic events that have left hundreds of dead, injured and innumerable material damages. Here is a list of the most relevant.
May 31, 1970
The magnitude 7.9 earthquake originated in the department of Ancash followed by a flood that buried the city of Santo Domingo de Yungay at 3:23 p.m.
This fact It is considered the most destructive earthquake in the history of the country.not only because of the magnitude but because of the number of fatalities it caused, estimated at 67,000according to the document “The earthquake of Ancash and the avalanche of the snow-capped Huascaran”, written by the geophysicist and scientific advisor of the National Institute of Civil Defense (Indeci), Mateo Casaverde, while there were also 150,000 injured, affecting in the same way to the departments of Huácamo, Lima and La Libertad.
Due to this catastrophe, in 1972 the government of Peru founded the National Institute of Civil Defense, in charge of devising plans to deal with this type of disaster and preparing national drills every May 31.
October 3, 1974
A magnitude 8.0 earthquake It was recorded in the capital, Lima, at 09:21 a.m., a movement that was also felt on the Peruvian coast to the south. The movement lasted about 90 seconds and left 252 dead and 3,600 injured.
May 29, 1990
Another earthquake of 6.4 caused the death of 77 people, left 1,680 injured, 58,835 homeless and 11 thousand homes destroyed. The movement, which began at 09:34 hours, left damage in the cities of San Martín, Amazonas, Cajamarca, Rioja, Moyobamba, Chachapoyas, Jaén and Bagua.
June 23, 2001
An earthquake of magnitude 6.9 affected the southern part of Peru in the regions of Moquegua, Tacna and Arequipa and left 74 people dead, 2,689 injured, more than 21,000 homeless, 64 people missing, 35,601 homes affected, of which 17,584 were destroyed.
The earthquake had several aftershocks and had an intensity of VIII, which generated a tsunami which also caused another 26 deaths. It was the most destructive tremor after the 1970 Ancash tremor and the largest in the world after the Rata Islands.
August 15, 2007
Peru was severely damaged by . Occurred at 6:40 p.m., the earthquake in Pisco de magnitude 8 lasted 3 minutes 50 seconds. It was one of the most violent earthquakes in Peru in recent years, being surpassed by the Arequipa earthquake of 2001. This fact left 596 people deceased.
May 26, 2019
One of the last earthquakes recorded in Peru was known as the “Loreto earthquake”, which had a magnitude 8 and originated at 02:41 local time and consequently left one person dead and more than 2,500 people affected.
