There are about 170 potentially active volcanoes in the U.S. The mission of the USGS Volcano Hazards Program is to enhance public safety and minimize social and economic disruption from volcanic unrest and eruption. We deliver effective forecasts, warnings, and information about volcano hazards based on a scientific understanding of volcanic processes to accomplish our mission.

Interactive map of volcanoes and current volcanic activity alerts in the United States

The U.S. Geological Survey's Volcanoes and Current Activity Alerts map shows the location and activity levels of all volcanoes in the United States. The map allows for filtering based on both location and current volcano status. Each volcano is depicted by a small colored triangle with different colors indicating various volcano alert levels: Green = normal Yellow = advisory Orange = watch Red = warning

Water contamination

Thermal Pollution Thermal pollution is the addition of heat to a cool environment, and it is caused by water or air used as cooling fluids in power plants and manufacturing that becomes heated in the process. Heated cooling water from power plants may be 15 ˚C (27 ˚F) hotter than lake or stream water, which increases metabolic rates in fishes and reduces the amount of dissolved oxygen that the water may hold. In extreme cases, it can be hot enough to burn animal tissues.

Thermal Pollution

Light Pollution Light pollution is unwanted or excessive light caused by streetlights and illuminated buildings, towers, and other structures. Light pollution changes nighttime visibility of natural features, disorienting migratory animals and fostering bird collisions with lighted towers and buildings.

Light Pollution

Plastic Pollution Plastic pollution is the addition of plastic waste to the landscape and waterways. It is caused by manufactured plastics that are not properly disposed of. It is a problem because plastic does not break down easily, the chemical additives in plastic may become endocrine disrupters, plastic waste flows downstream into rivers and oceans (sea life can ingest, choke on, or become trapped in plastic waste), and plastic is a source of polychlorinated biphenyls (PCBs), which are suspected carcinogens

Noise Pollution Noise pollution is unwanted or excessive sound that affects health and environmental quality. It is caused by machines and engines associated with industry, as well as airports and other transportation systems. Noise is problematic because it can cause physical damage to hearing organs in humans and other animals, it produces increased stress levels, and it disrupts ecosystems by driving certain species away and altering the habits of wildlife. Noise pollution occurs primarily on land located close to industry and transportation and at sea, where it emanates from ship engines and sonar.
