WEEK 3: EARTHQUAKES



    Many people have or may not have felt a earthquake in their lifetime. Earthquakes occur when faults break, which causes displacement on the Earth. Three different variations of faults can occur. We know this because of the direction they have moved. One of the faults is called a "Reverse Fault", this causes the block above the fault to lift due to compression. Another fault is a "Normal Fault", this causes the block above the fault to sink, exposing a Fault Plane on the surface of Earth. Another fault is the "Strike-slip Fault", that causes a vertical fracture on the earth resulting in the ground moving horizontally. Cuba is positioned among several active fault systems, resulting in typically two thousand earthquakes annually. Most of these earthquakes are ignored, although the island has faced numerous destructive earthquakes up to magnitudes of 7.0 or higher. I believe that because Cuba is not "seen" they cannot get the help they need in devastating times like this. Cuba is undoubtedly in a seismically prone area, with a long record of high-magnitude quakes. The southeast region of Cuba is believed to be the epicenter of most earthquakes in Cuba. 

    Mitigation is significant in life-or-death situations such as an earthquake. An individual must react calmly yet swiftly to allow themselves maximum security against the quake. People need to know how to react when uncontrollable dangers appear because it could save their and other people's lives. The first step would be to identify the hazard to visualize how you will face the situation. Another form of mitigation could be making earthquake-safe buildings that are meant to protect against natural hazards. Providing education on how to deal with situations like these is also very helpful because it helps build confidence and security in life-threatening events. 


USACE HQ on X: "What is Earthquake Mitigation? Earthquake mitigation is any action taken to reduce damages or losses to your business, employees, building, and building contents should an earthquake occur. https://t.co/3q57WuUw3c

    Its amazing to see how Cuba and morocco have similar safety pro cations for earthquakes also similar to Morocco is that not everywhere in Cuba gets earthquakes only certain spots.

WEEK 1: ABOUT CUBA

Image
Cuba is the largest tropical island located in the Caribbean, the average temperature is 79 degrees. Most of Cuba is made up of forests - covering about one-fourth of the surface area. The official name is the Republic of Cuba. There is a variety of different environments such as mountain forests to jungles and grasslands that unique animals call home. Cuba's original inhabitants were the Ciboney and Guanahatabey people. Later they would have the island taken over by the Taino people from Venezuela. Shortly after, American forces helped drive the Spanish out of Cuba in 1898, and by, 1902 Cuba obtained their own independence but with the strong influence of the United States over the island. A natural hazard is an event/process caused by the earth that potentially threatens human life and property such as houses, cars, etc. A disaster is an unpredictable event that takes place within a limited period and specific area. A disaster would declare a state of emergency, affecting over 10...

WEEK 2: TECTONIC PLATES

Image
 Tetnoic Plates are massive rocks under the earth's surface, generally composed of continental and oceanic lithosphere. Cuba is a part of North America, separated from the Caribbean plate by the Oriente Transform Fault. The North American Plate is the Earth's largest tectonic Plate, behind the Pacific Plate. This plate is part Oceanic and Continental. The Southern boundary with the Cocos Plate to the west and the Caribbean Plate to the east is a transform fault, represented by the Swans Island Transform Fault under the Caribbean Sea and the Motagua Fault through Guatemala.  Works Cited  https://rock.geosociety.org/net/gsatoday/archive/26/10/article/i1052-5173-26-10-4.htm#:~:text=Cuba%20is%20the%20largest%20island%20in%20the%20Greater%20Antilles%20and,NOAM)%20since%20late%20Eocene%20time.  https://www.researchgate.net/figure/a-Tectonic-map-of-the-Caribbean-showing-the-position-of-Cuba-as-a-part-of-the-North_fig3_252786886  https://en.wikipedia.org/wiki/North_Amer...
