Internal Displacement and Recovery from a Missouri Earthquake

If a major earthquake occurs in the New Madrid fault in the southeastern state of Missouri, at least 42,000 Missouri houses were destroyed and at least 83,000 homes could have been moderately damaged. This number applies only to Missouri state. Missouri deprives the other seven countries in the region and resources and it is also damaged. Three days after the incident, the climax of refugees in all eight states is estimated to reach 2 million people (Elnashai, Jefferson), Fiedrich, Cleveland and Gress, 2009), as the earthquake caused by the earthquake was eliminated.

From 2008 to 2014, according to the data of the National Evacuation Surveillance Center (IDMC), an average of 26.4 million people evacuated every year due to natural disasters such as earthquakes and floods. IDMC recognizes that climate change plays an important role in these disasters, as climate change changes normal weather patterns and makes disasters "more serious and frequent". Their report also stated that climate change "expands the tendency of evacuation."

Although Port-au-Prince is greatly affected by the earthquake four and a half years ago, although it still faces many challenges, recovery is progressing. More than 90% of the families evacuated moved from refugee camps to safer communities, more children attended school, and residents are now improving access to water and other basic services . In Haitian countryside, getting clean water is not always easy. In fact, about 40% of the rural population in Haiti uses unprotected water sources such as rivers and unprotected wells, so the risk of diseases such as cholera is elevated. By contrast, in cities, people who can not access clean water have a higher chance of purchasing bottled water and easier management of the disease.

The main mechanism (or cause) of the tsunami is massive water movement or sea disturbance. This water movement is usually caused by earthquakes, landslides, volcanic eruptions, glacial calves, vermiculite and fewer nuclear tests. The waves thus formed are maintained by gravity. If the ocean floor suddenly deforms and moves vertically on the water surface, a tsunami may occur. Structural earthquakes are special earthquakes related to deformation of the Earth's crust. When these earthquakes occur at the ocean floor, the water above the deformed area moves away from its equilibrium position. More specifically, if a thrust fault associated with a convergent or destructive slab boundary suddenly moves, a tsunami may occur and cause moisture migration due to the vertical component of the involved movement.
