New USGS-FEMA study highlights economic earthquake risk in the United States
Natural Hazards Mission Area
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.

Estimating aftershock risk for entry into earthquake-damaged buildings Estimating aftershock risk for entry into earthquake-damaged buildings
We present a simple method to estimate the risk of experiencing strong shaking from aftershocks during entry into earthquake-damaged buildings. We compute wait times until the probability of strong ground shaking from aftershocks reaches a predefined risk threshold; for example, a 0.4 percent probability of experiencing Modified Mercalli Intensity 7 or greater shaking during the planned...
CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform CRESCENT earthquake dynamic rupture, earthquake cycle, and tsunami code verification platform
Physics-based simulations are critical for understanding natural hazards. The increasing complexity of numerical codes requires benchmark exercises to verify that different computational methods yield consistent results when solving the same governing equations. Here, we present an open-access web platform designed for the verification of earthquake dynamic rupture, seismic cycle, and...
Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars
Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase-rich light-toned float rocks. SuperCam identified the distinctive signature of corundum (α-Al2O3) in these...

2026 Nepal Debris Avalanche and Flash Flood
On Wednesday morning (local time), 26 August 2026, a catastrophic debris flow and flood was likely triggered by rapid slope failure involving a glacier in Lāṅṭāṇ National Park, Nepal, near the border with China. This debris flow and flooding travelled nearly 100 km and impacted populated areas downstream along the Lende Kholā and Trishuli̇̄ Kholā rivers, including the Rasuwāgaḍhi̇̄ border post...

2026 Venezuela Sequence Earthquake-Triggered Landslide Hazards
On Wednesday, June 24th, 2026, a pair of earthquakes of Magnitude 7.2 and Magnitude 7.5 occurred in northern Venezuela, west of Caracas. The U.S. Geological Survey (USGS) Ground Failure product estimated that landslides triggered by this earthquake would likely be significant in number and/or spatial extent. This landslide event page serves to communicate timely science information to our partners...
