The Aleutian Islands
The Aleutian Islands and why to visit or live there
The Alaskan or Aleutian islands are a beautiful place to live. But most of the islands remain uninhabited. The population is 8,162. Weather there is often found to be upper thirty’s or forties. With kind of a stormy climate, but when it is clear you can see the Alaskan island off in the distance. And you surrounded by the beautiful waters of the Bering Sea. There is also plenty of wild life there to see, on land and in the sea. Sounds like a wonderful place to see, but.
What plates and boundaries it is located on and why this effects the Island
The Aleutians islands are on the North American tectonic plate. They are almost directly onto of and convergent boundary. Or where the North American and the pacific plats collide and push up against each other and one plate often slips under the other. This creates volcanoes because the bottom plat often becomes molten and rises. On the case of the North American and, the pacific plate, the pacific slip under the North American because it is heavier and denser. This is what causes this to be a dangerous place.
What makes them deadly and how.
These islands can also be one of the most deadly places in the world. They can up to nine earthquakes in one week. And they come with no warning what so ever. These Earthquakes can reach a magnitude of over five on the Richter scale. And it is not only earth quakes you will need to watch for but there are over thirty active volcanoes on these islands. Volcanoes and earthquakes kill up to 300 people each year in the Aleutian Islands. This is why the Aleutian Island are considered deadly.
Punta Arenas and Valdivia, Chile
Southern Chile is known as the Archipelago. It expands about 1,000 miles ending at the tip of South America at Cape Horn. This region has steep, rocky slopes, dense forest, glaciers, and lakes. Few people live here. Punta Arenas is the only major settlement in the area. Most of the land is not suitable for growing crops. Farmers do raise sheep in pastures.
There is tectonic plate activity because of a subduction zone. This is the Nazca Plate and the South America Plate on the Peru-Chile Trench. It is 21 miles deep. Subduction zones usually produce the strongest earthquakes on earth. The last earthquake’s rupture zone was 800 km long.It is one of the most dangerous places on earth because it is in a subduction zone. This causes earthquakes which cause landslides. There are not major deaths because very few people live there. However, one landslide caused a river to dam up which then burst making a flood flow down a valley. Another time a landslide closed a major highway. Earthquakes can cause tsunamis with waves up to 82 feet tall. About 100,000 people live in this zone.
This article has been shocking because there is a lot of dangerous places out. Earthquakes and volcanoes are the most shocking around the globe. some of the most dangerous places are Solomon islands, Japan, Alaska, and Colombia. I think those are the worlds dangerous places.
Most of the Colombian population lives in sprawling cities all over the country. But most of the large cities are along the western coast at the foothills of the Andes Mountains. Colombia has an amazing climate. They hover around the same temperatures most of the year unless there is a storm which causes the temperature to drop some degrees.
Columbia is in the northern part of South America close to the equator. Columbia lies on two plates, these plates are the South American Plate and the Nazca Plate. These plates are on a convergent boundary meaning that one plate slides beneath the other at a subduction zone. A volcano can be caused at this boundary because when one plate slides under the other it creates a space for the magma to flow up. This type of boundary is notorious for causing earthquakes and volcanoes making this place very dangerous to live.
The western part of Columbia is a very dangerous region because there are many active volcanoes that are known for causing a lot of damage to the surrounding area. What also makes this area one of the top most dangerous places is that they have almost no warning before an earthquake occurs. This is bad because most of the earthquakes that happen in this region are of high magnitudes. The average is about a 5.6. Also because of the location of the towns there is a great possibility that mudslides can occur after earthquakes. Over seven million people live in this area making it a prime target for high death and injury rates. Because all of the towns are big even the smaller earthquakes can cause damage.
