Caution! These Places are Dangerous

Oregon is the Place to Be!
What Really Happens Under the Surface?
Tectonic plates cover the whole Earth and one of the places that gets a lot of tectonic plate movement is Oregon. The Juan de Fuca plate is Oregon’s main tectonic plate. The plate that takes up some area in this state is the Pacific Plate. Oregon is in a convergent boundary so it is in a destructive area. This means that Oregon gets a lot of tectonic action. The Juan de Fuca and Pacific Plate move toward each other causing one plate to be forced down and the other moves up forming a hill or mountain. This is why Oregon is filled with mountains. Earthquakes and volcanoes are formed as a result of the pressure, friction, and plate material melting in the mantle. Earthquakes and Volcanoes are common in convergent areas. When the two plates move toward each other that causes continental collision or a formation of a subduction zone. Subduction zones are formed when a oceanic lithosphere and the earth's mantle collide forcing the earth’s mantle to move upward. The mountains in Oregon such as: Mt. St. Helen, Three Sisters, ect. are examples of tectonic plate movement. These mountains are results of continental collision and subduction zones. This magnificent place has catastrophes almost daily, and there are facts to prove that.
The Numbers Tell the Truth.No one ever really knows when they have the right facts about tectonic movement until they see the numbers. The highest richter scale rating in Oregon to ever happen was at the coastline of Oregon and California near Brookings, Oregon, on November 23, 1873, with an estimated 6.8 magnitude. With records of a 7 Crater Lake holds the highest spot on the VEI scale in Oregon. There are over 1,000 earthquakes a year here. The last volcanic eruption to happen in Oregon (Mount Hood) was in 1866. Oregon is on the west coast of the United States so that gives high chances of tsunamis. The last major tsunami to occur in Oregon was in 1964 the wave reach over 45 ft. above the shoreline. This state is considered one of the most dangerous places in the world. Any convergent place is considered dangerous, but Oregon sits on two of the most active tectonic plate in the world. If someone lives there they have to be cautious. There is a chance of having a 9.0 earthquake every 300-800 years on the coast of Oregon. These are risks that people have to be willing to take if they live here.
Heading - Tropical tour
Puerto Rico is located between the Caribbean Sea and the North Atlantic Ocean. Puerto Rico is a tropical place with around 80 degrees weather in the summer and 70 degrees weather in the mountain area. People from Puerto Rico speak the language spanish and English. Puerto Rico uses US dollars and coins. Driving in Puerto Rico could get a little confusing. People still drive on the right side of the road but the signs are in spanish and the gas is in liters. If someone were to visit Puerto Rico they would definitely see a beach Puerto Rico has such beautiful scenery like the blue cobblestone paved streets. Puerto Rico is on a plate boundary so, it is very dangerous.
Heading - Plate danger
The Puerto Rico trench is the deepest part of the atlantic ocean which is 8,400 meters deep. The trench is created from the Northern American plate and the Caribbean plate. It started to form about 70 million years ago after the two plates started to grind past each other. This is a convergent boundary which means the plates are moving towards each other colliding. This boundary is very destructive because of subduction causing movement downward into another plate. When the plates collide it causes large amounts of friction that rise to the earth's surface making earthquakes and volcanoes happen. In Puerto Rico there are no active volcanoes. One landform made from tectonic activity is the Cordillera Central Mountains. This is the main mountain range in Puerto Rico. Its highest peak is 4,390 feet high.
Heading - Dangerous Quakes
Even though Puerto Rico is a tropical paradise, it has danger to. Puerto Rico has had tons of Earthquakes. There are no active volcanos in Puerto Rico though. Earthquakes happen daily with magnitudes ranging from 2.0 - 8.0 on the richter scale. These earthquakes are happening daily. Most of the time the quakes are not felt by humans. The highest richter scale rating for a earthquake in Puerto Rico is 8.0 in North Puerto Rico leaving many buildings damaged and hundreds dead.This earthquake happened May 2nd 1789 which is over 100 years ago. Many tsunamis happen after these large earthquakes.The earthquakes still happen daily but with a average magnitude of 3.5 - 4.0 on the richter scale. Puerto Rico may be beautiful but, it's still one of the most dangerous places in the world.

Why you should live there
The Philippines are a great place too live because first off Filipinos are among the kindest people on earth, two the Philippines are a much easier place too fit in with other people, and three, the beaches are incredibly beautiful and warm, and also some of the best on the planet.
Why it has Earthquakes and Volcanos
But the Philippines also have volcanoes and earthquakes. The reason for the earthquakes is because the Philippine and Eurasian plate tectonics are convergent too each other which means that will crash or crunch together causing the vibration we call earthquakes. But there are volcanoes caused by the plate tectonics also. When the tectonic plates push together they can't keep going forward so eventually the force of pressure causes the front of the too push upward and push the ground with it, making it mound and form a volcano. It's also has Sierra Madre Mountain range. That mountain range is the biggest in the Philippines. It was created the same way volcanoes are made, the tectonic plates pressed together not able to push each other back they pushed up with the pressure. When the plates pressed up they pushed up the earth with it creating the mountain
Why it's dangerous
But, though the Philippines are beautiful, they are also very dangerous. There are at least 15 earthquakes a year and they have gotten up too a 7.8 magnitude. About 100 people a year are killed by earthquakes. Although they are dangerous, Earthquakes are not the only nature made threat. There are 18 active volcanos. Even though the last Volcano eruption was 2010 just makes the risk of another eruption far greater. The biggest volcanic eruption, in the Philippines, was made by mount Pinatubo, June 15 1991. The eruption caused high-speed avalanches, giant mud flows, and a cloud of volcanic ash hundreds of miles long. Although over 500 people were saved, thanks too prediction of the eruption by scientist, $250 million in property was not.
Why people want to live in Pompeii?
People want and do live in Pompeii,campania italy, though aware of the dangers. One of these reasons is the rich soil the volcanic ash creates. Another is the Scenery of the volcano. Though it is dangerous it is also very beautiful.
My last reason is it is a huge tourist attraction because of the well preserved bodies that were preserved because of the fast and intense ash cloud and cooling. Many were preserved doing exactly what they were doing before the volcano erupted.
The terrible Plate Tectonics
The Eurasian and African plates make up the convergent boundary in which lies the dangerous Mt. Vesuvius and the deadly earthquake cause. The Eurasian plate is currently pushing the african plate. So the african plate in retaliation is subducting and slipping underneath the Eurasian because of the pressure. Soon leading the the forming of many Earthquakes and Mt. Vesuvius.The subduction zone does this by the lower plate sliding under the upper plate pushing it up making one release magma forming a volcano. The subduction zone causes earthquakes kind of the same way because it is slipping all the time and when the pressure gets to be too much they slip fast creating the vibrations we call earthquakes.
The Deadly Pompeii
Pompeii is one of the world's most dangerous places because it has a convergent boundary and the volcano Mt. Vesuvius nearby. This volcano is why we have the petrified bodies preserved so well. We also owe the volcano for the VEI factor of 6 of 7 for it’s long and explosive eruption. Not only is Vesuvius one of the most dangerous volcanos,Being a Stratovolcano, It also is not yet dormant and could erupt anytime! The Number of lives it has claimed is around 2,000. The Volcano is hundreds of thousands years old. It has also Erupted more than 50 times through history. There is sometimes 2,000 years between eruptions but it still is not safe for it is as I said before still active. Other than Vesuvius there is the problem of the earthquakes That take place around this area everyday. In calculations there are about 2 earthquakes per day depending on the day. Whereas the Rating of these earthquakes are unnoticeable they mean the plates are shifting and agitating this volcano area thus aggravating the volcano. The earthquakes have had some bigger ones but not many the biggest was right before Mt. Vesuvius erupted. It’s richter scale factor was a 5 or 6. The tsunami factor is a there but not as bad as say hawaii. It is only surrounded on 2 sides instead of all or three.
