Natural hazards and disasters in Latin America

Natural hazards and disasters occur widely throughout the world. Disasters can be costly both in terms of human lives and property and ecosystem disruption. Higher death tolls in developing nations may be the result of poverty, rapid population growth, urbanization, and inadequate communication facilities. The purpose of this study is to show patterns of major catastrophic events in Latin America so that their impacts can be evaluated and compared.Latin America was selected because of the variety of recent events commanding wide attention: earthquakes in Mexico, volcanic eruptions in Colombia, hurricanes and floods in Haiti, and drought and mudflows in Brazil. Spatial and temporal aspects of natural disasters are presented in nine tables and 21 maps. The tables give selected disaster data by country for volcanic eruptions, earthquakes, landslides, and atmospheric disturbances from the 16th century to 1989. Most data is derived from disasters occurring during the 20th century and include number of events, people killed, people affected, and U.S.$ damage. Maps show environmental settings for disasters and allow detailed comparison among countries. Floods account for the greatest number of major events in the most countries, earthquakes cause the most deaths and damage, while droughts affect the most people. Peru surpasses all others in susceptibility to major disasters. Assessment of vulnerability to hazards, improved economic opportunities, and an increased social and political concern for poor people should help reduce future losses from natural disasters in Latin America.
