Week 16: Final hazard report

Chile is exposed to various hazards, and they are all important to consider. Chile has problems with earthquakes, tsunamis, volcanic eruptions, floods, and a major drought. All of these hazards are dangerous; however, if we were to assess them by importance, then earthquakes and tsunamis are the most dangerous for Chile. This is due to its position on the Ring of Fire, which makes it very vulnerable to having seismic activity. Chile also lies on the South American plate, where it collides with the Nazca Plate. The Nazca plate subducts under the South American plate, which causes many earthquakes in the area. Since the Nazca plate is an ocean plate, this triggers the water movement that then turns into tsunamis. Thus, these reasons make Chile very prone to earthquakes and tsunamis that have impacted the country in many ways.  Earthquakes and tsunamis have impacted Chile in negative ways. There have been a lot of economic losses due to them. There has been destruction of facilities a...

Week 13: Coastal Hazards

Image
  Coastal Hazards are a problem in Chile because of its long coastline that stretches through most of South America. This makes Chile very vulnerable to coastal hazards such as high sea levels, coastal floods, and erosion. Coastal Erosions happen when waves crash over the shore, where they can cause displacement of land and sediment on the coastline.  According to some research at the Pontificia Universidad de Chile, 86% of beaches between Arica and Puerto Montt are retreating, with erosion rates increasing simultaneously.  Coastal erosion is important to help protect beaches, infrastructure, and is very expensive to repair any damages or irreparable damage. As time goes by, more and more beaches will start to shrink.  An example of this happening in Chile is in Santo Domingo and Los Molles, where they are experiencing a rapid beach retreat due the sea erosion. It is recorded that the beach in Santo Domingo is receding at a rate of 5.7 meters per year.  At Los M...

Week 10: Extreme Weather

Image
Chile is highly likely to experience extreme weather conditions, such as thunderstorms and heat waves. Since it has the Atacama Desert, which is the driest in the world, Chile has had ongoing droughts throughout the years starting in 2010. Chile has experienced a drought for over a decade that the World Resource Institute (WRI) even calls a "mega-drought".  Wildfires have also worsened due to climate change and have affected other natural disasters. As a result of these extreme weather conditions, there has been a scarcity of water.  Droughts have impacted Chile's agriculture and how they access water due to the limited amount and warmer conditions.  Extreme weather conditions such as droughts, heatwaves, and even floods are worse for rural areas due to them being further away from support from the city of Santiago. It is expected that the Atacama Desert will continue to become drier and rural areas have less water availability.  Some mitigation methods that the Chil...

Week 8: Mass Wasting

Image
 Chile's Mass Wasting  Chile does experience mass wasting due to its position on the Ring of Fire, but it is not only triggered by natural events like earthquakes, and heavy rain. Just gravity can have an effect on mass wasting! What is mass wasting? Mass wasting is when rocks, soil, or debris end up going downwards. This creates landslides, rockslides, mudslides, and even avalanches which are a part of mass wasting.  Chile has had many mass wasting activities from tectonic activities due to it being close to the Andes mountains. Earthquakes have triggered these mountains in the past.  An example of Chile having mass wasting was the Villa Santa Lucia mud landslide that occurred on December 16, 2017, in the southern area of Chile. What caused the deadly landslides was the heavy rainfall and weak land. This caused the mud to cause a lot of destruction to infrastructure and even resulted in 20 people dead. The president of Chile declared a disaster zone and ordered resc...

Week 5: Volcanos

Image
Does Chile have volcanos?  Chile is known to be prone to natural disasters since it sits along the Ring of Fire. This causes the country to experience earthquakes, tsunamis, and volcanic eruptions. Some of these earthquakes cause volcanic activity around the country. Chile has about 2,000 volcanoes and only about 60 are active. The Andes is where many of the volcanoes are at since it is on the south American plate where the Nazca plate subducts beneth it causing volcanoes to errupt due to the earthquakes. One of the most active and dangerous volcanoes in Chile is the Villarrica and the last major eruption was in 2023 after this it only has had some minor erruptions.  As a result, these volcanoes release ash and can cause bad air quality.  How does Chile take precautions/ mitigation measures?  Chile has volcanic erruptions every now and then and the Chile National Geology and Mining Servive known as (SERNAGEOMIN) helps monitor any geological activity and helps inform ...

Week 3: Earthquakes

Image
Chile's Earthquakes Chile is in a position that has many earthquakes since it sits on the Ring of Fire making it prone to earthquakes from seismic activity. The high amount of seismic activity causes these natural disasters to occur in the country more often than in other countries further away from the plate boundaries.  Chile has earthquakes often due to its close plate-to-plate contact that has convergent boundaries. In the image above you can see that it is in the red zone where severe earthquakes occur. Due to the subduction of the Nazca plate under the South American plate, many horrible earthquakes have occurred.  Chile had the biggest earthquake ever to be recorded at a magnitude of 9.5 in May of 1960. This earthquake lasted for a few minutes and caused a lot of damage to the country. There were many landslides due to the earthquake and it also caused a tsunami that killed many people. Additionally, this earthquake caused widespread damage to countries such as Japan, H...

Week 2: Tectonic Plates

Image
Chile   The Country Chile sits on the South American Plate with the Nazca Plate to the left/ western side of the country and has a lower border with the Antarctic Plate. Chile is near many tectonic plates which makes it prone to natural disasters. Chile's fascinating fact is that it is on the Pacific Ring of Fire which is an area that has earthquakes and volcano eruptions. Chile is on the convergent boundary, meaning there is a collision between two plates. In this process, the Nazca Plate subducts under the South American Plate because of the softer and more delicate. The ocean plate of Nazca ends up going under the South American Plate because of the softer and more delicate layer. This pressure caused the formation of the Andes Mountains which South America is known for.  After noting the following tectonic plates and boundaries Chile is known for being prone to having major earthquakes that result in tsunamis or volcano eruptions. Due to subduction from the Nazca...
