Hello everyone, I hope you all are doing well :) I chose to research the country of Peru because I’ve always had an admiration for the culture and half of my family lives in Cusco. It’s been very interesting learning about this country and I’m excited to explain what I have learned this week about Peru’s tectonic plates and boundaries. When I was researching I found out that Peru is on a convergent plate boundary. Looking back at this week’s lesson, I was able to understand that convergent means that Peru’s plates are “toward one another.” The countries of Peru and Chile have created a trench called the Nazca Plate (according to The Geological Society). It follows along the border of Peru and Chile and is also part of the Ring of Fire.The Nazca Plate is an oceanic plate that shares convergent and divergent boundaries which force underneath the South American plate at a rate of “4 cm a year” (according to The Guardian). Peru also contains the Altiplano plate which due to the ...
In Peru the occurrence of mass movement is very common in the Andes mountain area of the country. Landslides are a recurrence and have been affecting Peru since many years back. Today I wanted to present to you about three different landslides that hit the country of Peru in the past and earlier this year in 2021. Due to Peru’s steep mountain range and frequent earthquakes, mass wasting disasters have emanated from Nevados Huascaran (known as a tall mountain peak). In 1962, an avalanche from this peak fell at an average of 105 miles per hour and had a volume of 16,900,000 cubic yards. The debris from the avalanche buried the village of Ran-rahirca and killed 5,000 citizens. Eight years later, history repeated itself because a 7.7 magnitude earthquake hit Nevados Huascaran and the avalanche fell at 174 miles per hour. The debris ended up covering the town of Yungay and the death count was at 18,000. It seems that the Andes mountains are a common place for mass wasting and towns in ...
