It is difficult to determine the "worst" natural disaster as each disaster has varied impacts depending on factors like location and population density. Some of the most devastating natural disasters include earthquakes, tsunamis, hurricanes, and volcanic eruptions. The severity of the disaster is typically measured by the loss of life, property damage, and long-term impacts on the affected area.
Hurricane Katrina was considered the worst natural disaster in US history due to the widespread destruction it caused in New Orleans and along the Gulf Coast. The response to the disaster was criticized for its slow and inadequate efforts in evacuating residents, providing relief, and managing the aftermath, leading to loss of life and prolonged suffering for many affected individuals.
