An major magnitude-7.5 earthquake hit near Barranca, Datem del Marañón, Loreto, Peru on Sunday, November 28th, 2021, at 5:52 am local time at an intermediate depth of 112.5 km.

The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms.

But according to the latest images and videos, there is widespread damage to buildings, homes and roads.

France’s Réseau National de Surveillance Sismique (RéNaSS) listed the quake at M7.0, Italy’s National Institute of Geophysics and Volcanology (INGV) at M7.6, the German Research Centre for Geosciences (GFZ) at M7.4, Geoscience Australia (GeoAu) at M7.5, and the European-Mediterranean Seismological Centre (EMSC) at M7.5.

Many buildings as well as roads have been destroyed:

Many landslides hit:

They probably don’t know where they are going to sleep tonight!

These guys too:

It was a nice building prior the M7.5… Now it’s dust:

It will take long to rebuild:

Shakings have been reported in Ecuador, Colombia and Brazil. Ecuador also had some buildings collapsing.

Here some other videos of the aftermath of the strong quake.

This road has been cut off by landslides:

This major earthquake occurred within the lithosphere of the oceanic Nazca plate. The earthquakes of northern Peru and most of western South America are due to strains generated by ongoing subduction of the Nazca plate beneath the South America plate.

The Nazca plate moves east relative to the South America plate at a rate of about 7 cm per year. It is overridden by the South America plate at the Peru-Chile trench, west of the Peruvian coast, and sinks into the Earth’s mantle beneath the South America plate.

The subducted Nazca plate is seismically active to depths of about 650 km. This earthquake occurred in a segment of the subducted plate that has produced frequent earthquakes with focal depths of 100 km to 150 km beneath the Earth’s surface. A magnitude 7.2 earthquake in 1997 was situated 150 km to the north of the 26 September 2005 earthquake, at a similar depth.

Earthquakes that have focal-depths between 70 and 300 km are commonly termed ‘intermediate-depth’ earthquakes, as distinguished from ‘shallow-focus’ earthquakes, having depths less than 70 km, and ‘deep-focus’ earthquakes, having depths greater than 300 km. Intermediate-depth and deep-focus earthquakes represent deformation within subducted plates, rather than deformation at plate boundaries.

Intermediate-depth and deep-focus earthquakes typically cause less damage on the ground surface above their foci than is the case with similar magnitude shallow-focus earthquakes, but large intermediate-depth and deep-focus earthquakes may be felt at great distances from their epicenters.

A major M7.5 earthquake occurred in the same area on September 26, 2005 which killed 5 and injured at least 60. About 70 percent of the houses destroyed and at least 200 buildings damaged in Lamas. Again, this across Peru up to Quito, Ecuador, Bogota, Colombia and in the Amazonas and Rondonia states, Brazil. [Relief Web]

  1. Third Shaking of Planet is in full progress, Omicron if you take O of it is name of company who make chips… Please know when Iran attack comes will be quick and use of latest high tech… Iran will go in total darkness soon. Then Israeli planes will bomb hell out of Ayatollahs. Iranian will kill all Ayatollahs.

  2. Well Strange Sounds i predicted this in your page while a go.
    Look for DEC 4 Eclipse of Sun also will effect world . We are at no point of return , we all surrender to Queen of London or we all die.

  3. Ok, that first video. ” Terremoto —mierda” bleep, bleep, bleep, Mierda.

    That means earthquake, shjt, shjt, Holy Shjt.

    Lolollolllollllolllll
