A Comparative Study of the Chile and Haiti Earthquakes of 2010 and the Nepal Earthquake of 2015

Abstract: Earthquakes have been among the most terrifying natural disasters since prehistoric times. When gas within the Earth escapes through cracks in the surface or volcanic vents, the resulting voids are filled by the pressure from the Earth's surface above, causing earthquakes. Furthermore, the shifting and sliding of subsurface rocks over one another causes earthquakes. There are roughly six thousand earthquakes per year on Earth. Volcanic activity, sudden Earth surface changes, and landslides can all cause them. This paper presents a comparative study on three devastating earthquakes—the 2010 Chilean earthquake, the 2010 Haitian earthquake, and the 2015 Nepal earthquake—and contrasts them in this essay. Evaluating the damage as soon as possible and assisting with rehabilitation efforts to demonstrate compassion for the impacted populations is imperative. Assistance of this kind is necessary for efficient disaster response and recovery. We may determine significant primary, minor, and major effects and short- and long-term plans for precise forecasting, defense, and readiness by looking at these case studies. This synopsis emphasizes the difficulties these countries face in overcoming these tragic occurrences.This comparative analysis provides insights into improving earthquake resilience in developing nations.
