Explore a wide variety of videos that highlight natural hazards, the risks they pose and the science we conduct to better understand and prepare for them.
Learn about the natural hazards you might face and how science can help us be better prepared.
Earthquake hazards are a national risk, with nearly half of Americans living in areas prone to potentially damaging earthquakes. Learn about tools and resources that can help us all be better prepared.
To better understand the geophysical characteristics and seismic history of the Cascadia Subduction Zone, USGS researchers conduct fieldwork at sea to collect evidence of turbidity currents from underwater landslides likely caused by earthquake shaking.

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone in this monthly update for October 1, 2022.
The update comes to you from Artist Paintpots in Yellowstone National Park. The paintpots are acid sulfate springs, one of three different types of thermal features in Yellowstone.

During a geologic emergency response, scientists can be integral to the response by distilling complex, technical information for decision-makers. As a scientist assigned to an emergency response and a member of an Incident Management Team (IMT), the scientist must understand their role and how they can help decision-makers make informed decisions.

El aumento de riesgos por inundaciones a lo largo de nuestras costas está causado por el cambio climático, el desarrollo urbano y la pérdida de hábitat.

Coral reefs are important for supporting biodiversity, fisheries, tourism, and coastal protection, but are in decline worldwide, primarily due to extreme heat waves and subsequent coral bleaching, in addition to other stressors.

During the late Oligocene to early Miocene, the Marysvale volcanic field of southwestern Utah experienced three consecutive, catastrophic, mega-scale collapse events: the Sevier, Markagunt, and Black Mountains gravity slides, which we refer to collectively as the Marysvale gravity slide complex (MGSC).

Coral reefs act like submerged breakwaters by breaking waves and dissipating their energy offshore before they flood coastal properties and communities. This is an enormously valuable function: In 2017, Hurricanes Harvey, Irma and Maria alone caused over \$265 billion in damage across the nation.

This talk was presented at the 15th International Coral Reefs Symposium, 03-08 July 2022 (Hybrid event), under Theme 12, Conservation and Management, Session 12E: How can scientists and managers identify optimum catchment management actions to improve downstream condition for reefs and people?

The complex, three-dimensional reefs built by corals over hundreds to thousands of years provide invaluable ecosystem services to society—contributing billions of dollars per year to the global economy through shoreline protection, tourism, and habitat for biodiversity and fisheries.

Landslides display a broad spectrum of speeds for incompletely known reasons. Sliding occurs along slickensided undulatory shear surfaces within boundary shear gouge comprising clay mineral and non-clay (granular) particle mixtures, similar to tectonic fault gouge.
