Ocean hazard events like tsunamis, triggered by earthquakes and landslides, storm surges associated with hurricanes and extreme storms, oil and gas spills, floods and associated watershed contaminants, affect the health and safety of our Nation 's ocean and coastal communities and ecosystems. USGS scientists reconstruct the geologic past looking for evidence of natural hazards events including but not limited to tsunamis, submarine earthquakes, submarine landslides, and submarine volcanic eruptions to better understand their causes, timing and extent. |
