Hazards Information

Preparing for a natural hazards, whether a hurricane, tsunami, flood, or other event, can mean the difference between life and death. We've put together a list of major hazards and what you can do before and during an event to maximize safety and minimize loss.

  • Earthquakes

    View recent earthquakes on the Global Hazards Atlas. The U.S. Geological Survey estimates that several million earthquakes occur each year, but only a few of these are strong enough to cause significant damage. Large-magnitude earthquakes are among the most destructive hazards on Earth and can change the landscape over thousands of square miles. Learn More »

  • Tsunami

    View the locations of events that generated tsunamis from 49 B.C. to the present. Tsunami waves travel at speeds of 300-600 miles per hour (483-966 km/hr), and the first wave may not be the largest one. Although most tsunamis are caused by earthquakes in oceanic and coastal regions, they can also be triggered by underwater landslides and submarine volcanic eruptions that are powerful enough to displace the surrounding water.

  • Tropical Cyclones

    Read daily coverage of tropical cyclone activity and worldwide severe weather. Tropical cyclones produce heavy rainfall and sustained winds that can exceed 155 miles per hour (249 km/hr). PDC posts daily Tropical Cyclone Activity Reports on the Weather Wall year-round for the Pacific and Indian Oceans, and during the hurricane season for the Atlantic Ocean, Caribbean, and Gulf of Mexico.

  • Floods

    Find the Global Flood Survey on the Weather Wall. Floods are one of the most common hazards on Earth and have claimed millions of lives in the past 100 years. Flooding can be triggered by heavy rainfall, tsunamis, high astronomical tides, snow melt, ice jams, prolonged strong onshore winds, or a failure of dams/levees to trigger. Learn More »

  • Volcanoes

    View historic volcanic eruptions from the last 10,000 years. Volcanoes are one of Earth's most destructive natural events. Eruptions can cover large areas and dramatically alter the landscape. Learn More »

  • High Surf

    View significant wave heights for the world's oceans. High surf is triggered by storms or high winds in the open ocean that can create waves and can catch beachgoers off guard. Although general forecasts can be made about surf conditions, the timing of individual waves can never be predicted. Learn More »
