Magnitude 4.7 earthquake shakes Ica, Ica

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.
