       As if Haiti's misfortunes weren't enough, it is now in the midst of a dual catastrophe—earthquakes and hurricanes, which have left the island only as a wretched witness in ruins. The earthquakes are, geologically speaking, the result of the collision of two tectonic plates, North American and Caribbean at this very place combined with many faults in the area, the Enriquillo–Plantain Garden fault system running through the region being the most significant one. In this manner, the geologic setting is the ground for the strong and shallow earthquakes that may hit without prior notice, just like the earthquakes of 2010 and 2021. Natural disasters of comparable destructiveness characterize hurricanes as well. Haiti is located right underneath the zone of Atlantic tropical storms, and the island's environmental degradation is a large factor as well. Heavy rainfall caused by the storms combined with the steepness of the land can easily result in landslides and flood...

      The coastline of Haiti is eroding severely and more and more seriously, as the seas get higher, the tropical storms get stronger, and the large-scale deforestation of the mangroves, which provide the best protection, is going on. The combination of the rising sea and the storms is causing the beaches to recede more and more, thus damaging the infrastructure and making the coastal communities evacuate further inland. The deforestation of the mangroves for fuel and housing has been one of the main factors that reduced the natural barrier against the sea and that is why places like Les Cayes, Jacmel, and parts of northern Haiti are now very likely being flooded. These ecological factors, along with the heavy population in the coastal regions as well as the absence of good land use control, make it impossible for the people to hold onto their houses, fishing to be the only food and income source, and the growth of the economy to be sustainable in the long run. Haiti is ...

 Due to Haiti's location, they are susceptible to a numerous amount of extreme weather events. The most infamous one being the 2010 earthquake is easily the most devastating and notorious for the country's history. But due to being so close to the equator, they are also prone to dealing with hurricanes, tropical storms, and heavy rain. The last major hurricane to hit Haiti was hurricane Matthew on October 4, 2016. In 2021, a 7.2 magnitude earthquake hit the western part of the country, being the second biggest earthquake in the country's history behind the 2010 earthquake. Because of the island's location, being extremely close to the equator as well as it's tectonic plates, it makes Haiti extremely venerable to potentially very harmful extreme weather events.  Source: https://concernusa.org/news/haiti-timeline-history/#:~:text=2016:%20Hurricane%20Matthew%20hits%20amid,a%20lack%20of%20humanitarian%20funding.

       Haiti's geography and tectonics combined create conditions that are conducive to landslides, which are a type of mass wasting. One of the consequences of the 7.0 earthquake on January 12, 2010, was the summation of landslides up to 4,500, all of them occurring on a 2,150 km land surface. The slope failures which consisted of falling rocks, debris flooded down, and ground slipping, did not get distributed randomly. Instead, they were mostly clustered in areas where the combination of steep mountains, rough terrains along with complex fault activities had taken place. A prime example of this is the region around the intersection of the Léogâne blind thrust fault and the Enriquillo–Plantain Garden Fault. Interestingly enough, in comparison to other earthquakes, the landslides mostly occurred not above the main rupture area (hanging wall) but in high land that was uplifted. This is a clear case where topography and rupture dynamics dominate the distribution of lan...

Blog Week 5: Volcanoes in Haiti

Image
 Haiti is not known for any recent volcanic activity. Haiti has two known volcanoes: Morne la Vigie and Thomazeu. But, they are considered to be, "Pleistocene Volcanoes," aka extinct. Both previous volcanoes are described to be north of the capital Port-au-Prince. The two volcanoes are described to have been active around 1.5 million years ago. Haiti's most prominent natural disasters are earthquakes and hurricanes due to the country's location near to the equator as well as being set between two complex fault systems.  Sources: https://www.sarakauss.com/thomazeau-haiti-live-beyond-day-4/ https://volcano.si.edu/volcanolist_countries.cfm?country=Haiti#:~:text=Haiti%20has%200%20Holocene%20volcanoes,Minor https://www.wikiwand.com/en/articles/Thomazeau_Volcano

Week 3: Haiti & Earthquakes

Image
 For the country of Haiti, it is most famously known for its catastrophic and life-altering earthquake that occurred on January 12, 2010 in the southern part of the country, not too far off from the capital, Port-au-Prince. Haiti does experience very mild earthquakes often, almost happening daily. While analyzing the seismicity map of the 2010 earthquake, it illustrates which parts of the country were most affected, felt some of the earthquake and which received little shocks. Some of the ways that you can prepare for a hurricane are by creating a supply kit that includes all the essentials that would be needed for you and your family, as well as mapping out specific places of protection to reside.  Sources: https://culturalrescue.si.edu/why-it-matters/our-impact/haiti-2010-haiti-earthquake#:~:text=The%20catastrophic%20earthquake%20that%20struck,Led%20by%20Dr. https://earthquakelist.org/haiti/#all-latest-earthquakes https://www.britannica.com/event/2010-Haiti-earthquake

On the Caribbean Sea, specifically on the island of Hispaniola,  Haiti resides near an extensive tectonic fault. It presides at the boundary of the North American and Caribbean plates, ranking it to be one of the most diverse tectonic regions in the area. The adjacent area of Haiti is shaped as a transform boundary, where plates move in lateral directions.   Source: https://www.internetgeography.net/topics/haiti-earthquake-2010/#google_vignette
