Earthquake Hazards
Home
The USGS monitors and reports on earthquakes, assesses earthquake impacts and hazards, and conducts targeted research on the causes and effects of earthquakes. We undertake these activities as part of the larger National Earthquake Hazards Reduction Program (NEHRP), a four-agency partnership established by Congress.

Can a deep-learning approach perform better than NEIC’s traditional methods to get more accurate earthquake locations and magnitudes? The NEIC monitoring system is a perfect candidate for deep learning because it processes large amounts of data.

USGS Seeks Earthquake Hazards Research Proposals
The U.S. Geological Survey (USGS) is currently soliciting project proposals for Fiscal Year (FY) 2022 grants on earthquake hazards science and is authorized to award up to $7 million. The deadline for applications is June 1, 2021, and interested researchers can apply online at GRANTS.GOV under funding Opportunity Number G22AS00006.

A review of timing accuracy across the Global Seismographic Network
The accuracy of timing across a seismic network is important for locating earthquakes as well as studies that use phase‐arrival information (e.g., tomography). The Global Seismographic Network (GSN) was designed with the goal of having reported timing be better than 10 ms. In this work, we provide a brief overview of how timing is kept across...

The Global Seismographic Network (GSN) is a multiuse, globally distributed seismic network used by seismologists, to both characterize earthquakes and study the Earth’s interior. Most stations in the network have two collocated broadband seismometers, which enable network operators to identify potential metadata and sensor issues. In this study,...
Ringler, Adam T.; Anthony, Robert E.; Dalton, C. A.; Wilson, David C. Physics‐based evaluation of the maximum magnitude of potential earthquakes induced by the Hutubi (China) underground gas storage
The world’s largest underground gas storage facility in Hutubi (HUGS), China, is a unique case where cyclic gas injection‐extraction induced both seismicity and ground deformation. To assess the potential for future induced seismicity, we develop a framework physically based on a well‐constrained hydro‐geomechanical model and on fully coupled...
