The US Geological Survey (USGS) is a scientific agency of the United States government. Established in 1879, its primary mission is to study the natural resources and natural hazards of the country. The USGS conducts research on various topics, including geology, hydrology, biology, and geography, providing valuable data to help manage the nation's resources and protect the environment. The agency plays a crucial role in monitoring natural disasters such as earthquakes, floods, and volcanic eruptions. By providing real-time data and assessments, the USGS helps communities prepare for and respond to these events, ultimately contributing to public safety and informed decision-making regarding land use and resource management.
