Dangerous Locations

Introduction

Screams come from all around, and panicked families run through the streets seeking protection. This is a common scene in places with much tectonic plate activity, but what makes a place so dangerous? Population, frequency, and the history of plate activity all play a role in defining whether or not a place is dangerous. In this article, the dangers of Chile, Shaanxi, China, and Naples, Italy will be explained and reasons why they are some of the most dangerous places on earth.

Chile - By Sydney

Location

Along the western side of South America, sits the long, narrow country of Chile. With 4,000 kilometers of coastline, you can find many beaches and steep cliffs. The Andes Mountains tower to the east of the country, while the Pacific Ocean is settled to the west. Since the country is so long it has a wide variety of climates. Chile is important and well known for their mining industry. Many jobs are created through this business. Worldwide there is a need for copper, and Chile can supply that copper. Other main jobs in the country include agriculture, forestry, and fishing.

Tectonic Activity

About 62 miles off the coast of Chile, the oceanic Nazca Plate meets the continental South American plate. A subduction zone is created at this meeting point. Where the two plates meet a large trench is located on the ocean floor. The Nazca plate slides an average of 1.5 centimeters under the South American plate every year. The subduction of the two plates also creates the volcanic mountain chain called the Andes. As the oceanic and continental plates meet, the continental plate begins to buckle. This, along with the melting rock or magma forms the mountains.

The Dangers

The plate movement in this region is known to cause large earthquakes and the forming of many volcanoes. There are hundreds of active and dormant volcanoes in the Andes. With 36 historically active volcanoes, Chile has had the largest number of volcanoes in that region. They are also ranked fifth among other nations. A report from tradingeconomic.com says that Chile’s population is 17.3 million people. With that size of a population more people are in danger if a large earthquake would strike. Many earthquakes in the ocean cause large tsunamis causing great destruction and death. Two of the top ten largest earthquakes happened in Chile, and many other strong quakes have occurred. Chilean cities may also have tall buildings. This creates the danger of crumbling and falling debris injuring people.

Shaanxi, China - By Faith


In China there is a region with a diverse array of climates, and environments. In some sections of this region they have hot summers and very frigid winters, but in others it is subtropical and there are very mild temperatures. Many people come to visit this region of the world because of the beautiful scenery and the vast range of climates. A tourist’s attraction would be the Loess Hills where people in the earlier Chinese culture built their homes. People live here because of many different reasons; beautiful scenery, climates fit for anyone’s liking, and many different collages, and Universities that are open for schooling. Are people making good choices by choosing to live here due to tectonic activity? That’s what we’re going to find out.



Shaanxi, China sits on the Eurasian plate, which moves east and down towards Australia. It’s only a few hundred miles from a major plate boundary. This boundary is the Indian plate. Shaanxi, China sits on top of a dip-slip fault. This type of fault occurs where rocks are pulling apart. When rocks pull apart it causes vibrations to flow, and that causes an earthquake. This type of fault can cause very dangerous earthquakes.



This type of fault can be very harmful to humans living in that area because rocks are often pulling apart which causes the earthquakes to occur. When an earthquake happens buildings can fall and cause pipelines to burst. Flooding can wash away other smaller buildings along with people, and their belongings. Earthquakes can also cause power outages. Tsunamis are caused by earthquakes, and other places are affected by these. Flooding can occur, and also the destruction of towns, and villages. When an earthquake occurs it causes other events which can cause other places to be affected by it. Earthquakes are one of the most dangerous natural disasters.

Naples, Italy- By Jenny

Location

Naples is in the region of Campania in Southern Italy, about 2-hours south of Rome. It sits on the coast on the northern edge of the Bay of Naples, one of the most beautiful bays in Italy. Its harbor is the most important port in Southern Italy. With the population of over 900,000 people this city has many tourist attractions such as the National Archaeological Museum, Duomo, shopping, the harbor, castles, and other museums. This city has many things to do and is a great place to live and visit.


Tectonic Activity

Italy sits on the Eurasian plate, which is undergoing a continental-continental convergence with the African plate to the south. It is definitely a primarily convergent boundary a convergent boundary is when one tectonic plate moves under another tectonic plate causing earthquakes.


The Dangers

Italy is known for one of the most dangerous volcanoes in the world, Mount Vesuvius. The deadly power of Vesuvius was dramatically demonstrated in AD 79, when a monumental eruption wiped out the Roman cities of Herculaneum and Pompeii. The last eruption was in 1944. As for earthquakes in 1693 an earthquake hit southern Italy, killing an estimated 60,000 in Catania, Sicily, and 93,000 in Naples. That earthquake had a 7.4 magnitude. The more recent earthquake in 2012 a 6.0-magnitude quake killed seven people and toppled centuries old buildings. This information makes Naples, Italy a beautiful place to visit but can also be very dangerous.

Conclusion

Earthquakes and volcanoes can be very deadly, and can destroy cities and hurt country’s economies. Depending on the location of where one lives, the plate activity is different and can do different kinds of damage throughout the city. Although some of these places in the world are very dangerous, people still choose to live there because of their natural beauty.
