The Nazca Plate Creates Deadly Earthquakes

 

 The Nazca Plate has three triple Junctions
The Nazca Plate is a small oceanic plate of the coast of South America. It has five triple junctions where three different plates come together. It also produced the largest earthquake ever recorded by seismographs in 1960. 

 The Formation of the Andes Mountains
The Andes Mountains have formed on the continental side of the subduction zone that lies between Nazca crustal plate and the South American Plate. The Peru-Chile Trench separates the two plates.
The Eastward Motion of the Nazca Crustal Plate
The absolute eastward motion of the Nazca crustal plate is one of the fastest of any tectonic plate on Earth. The absolute motion is 3.7 cm/yr eastward.

 The two largest  Earthquakes In Recent Past
Massive earthquakes that have occurred due to subduction of the Nazca Plate beneath the South American Plate.

  • The May 22, 1960 earthquake near Valdivia was 9.5 on the moment magnitude scale.
  • The February 27, 2010 earthquake in the Maule Region of Chile was an 8.8 moment magnitude earthquake.

Colombia's Weather

Image
 Colombia's Weather Colombia experiences a variety of extreme weather conditions due to its diverse geography. It can range from tropical rainforests to high altitude mountains, resulting in varying temperatures,  rainfall, and humidity throughout  the country. Colombia's weather can be quite fascinating. In some regions, you'll find hot and humid conditions, especially in the coastal areas. On the other hand, higher altitude areas, like the Andes Mountains, can have cooler temperatures and more frequent rainfall. It's this diversity that adds to the charm and uniqueness of Colombia's climate. In an article called "Colombia Weather" it mentions " Colombia is located near the equator so it does not have extreme variations in temperature, although there is a wet and dry season. The climate changes with the altitude, hotter at sea level and cooler at higher elevations, with some peaks bearing snow year round. Temperatures below 2,953 feet average between...

‘final hazards report’

Image
Main natural hazards In Colombia Earthquakes Earthquakes occur in Colombia due to its location along the Pacific Ring of Fire, which is an area of intense seismic activity. Colombia is situated where several tectonic plates meet, including the Nazca plate, the Caribbean Plate, and the South American Plate. The interaction between these plates creates seismic activity, resulting in earthquakes. The subduction of the Nazca Plate beneath the South American Plate is one of the main causes of earthquakes in Colombia. This subduction zone , known as the Colombia-Ecuador Trench, can generate powerful earthquakes. Earthquakes in Colombia are a priority because they pose significant risks to the safety and well-being of the population. Colombia is located in a seismically active region, and earthquakes can occur with varying magnitudes. These seismic events can cause widespread damage to infrastructure, homes, and other buildings, leading to injuries and loss of life. Addressing the earthquake ...

Colombia Is No Stranger To Earthquakes

Image
  Colombia is no stranger to earthquakes, In 1983 a magnitude of 5.5 earthquake killed around an estimate of 380 people, and injured a further of 2,000 people and left 10,000 people homeless. Then over a decade later, near the city of Armenia anther earthquake hit. This time it was 6.2 magnitude  and it killed about 2,000 people and caused about $1.2 billion in damages.  The Colombian authorities have recognized this threat, and have taken measures to reduce its potential impact. Colombia passed several codes for seismic-resistant buildings. Directives to improve excising construction with the aid of subsidies is another measure, as well as redevelopment initiatives and in some cases even free housing programs.  https://www.weforum.org/agenda/2015/10/how-colombia-is-preparing-for-its-next-earthquake/
