Natural Hazards
Every year in the United States, natural hazards threaten lives and livelihoods and result in billions of dollars in damage. We work with many partners to monitor, assess, and conduct targeted research on a wide range of natural hazards so that policymakers and the public have the understanding they need to enhance preparedness, response, and resilience.
Reducing Risk
USGS scientists develop new products to make science available to the public, emergency managers, and decision-makers. These efforts increase public safety and reduce risk and economic losses caused by natural hazards.

The most powerful earthquakes, tsunamis, landslides, and volcanic eruptions occur in subduction zones, where two plates collide and one is thrust beneath another.

Natural Hazards Newsletter - Inaugural Issue - Vol. 1 | Issue 2021-Winter
We introduce the USGS Natural Hazards newsletter. In this issue: A new geonarrative about the 2019 Ridgecrest earthquake, Potential landslide in Alaska, Subduction Zone Science, Post-wildfire debris flow assessments, new @USGS_Quakes Twitter account, Mapping faults in Puerto Rico, Coastal Change Top Story, Photo Round Up and more!
USGS Reducing Risk Website
The Reducing Risk website under the USGS Natural Hazards Mission Area showcases the USGS Risk Plan and pulls together research and activities from around the USGS that focus on the goals of the plan: to advance USGS capabilities in risk assessment, mitigation, and communication.
Follow Earthquake Tweets
The USGS launched a new social media account (@USGS_Quakes) run by earthquake scientists and staff to "provide context for significant earthquakes and insights into seismic science."

Exposure of an early to middle Noachian valley network in three dimensions on Mars
We document a set of channels in a section of the Martian cratered highlands located between crustal massifs northeast of Hellas Planitia that are visible in cross section and planview >200 m below the surface. The morphometry and spatial distribution of the outcrops provide concrete geological evidence of a dynamic aqueous system in a...

Geologic map of Jezero crater and the Nili Planum region, Mars
The cratered highlands located northwest of Isidis Planitia have been recognized as one of the best preserved Noachian landscapes currently exposed on Mars; the area hosts a record of diverse surface processes, diagenesis, and aqueous alteration. This region has consistently been considered a high priority for landed-mission exploration and...
Sun, Vivian Z.; Stack, Kathryn M. Planetary cave exploration progresses
Planetary caves have been identified on the Moon and on Mars, and are likely to occur across the Solar System. They present a new frontier for planetary science, subsurface astrobiology, geology and human exploration. The fourth in a series of scientific meetings focusing on the science and exploration of planetary caves brought together 55...
