Hayward Fault Earthquake Simulations Increase Fidelity of Ground Motions

In the next 30 years, there is a one-in-three chance that the Hayward fault will rupture with a 6.7 magnitude or higher earthquake, according to the United States Geologic Survey (USGS). Such an earthquake will cause widespread damage to structures, transportation and utilities, as well as economic and social disruption in the East Bay.

Oklahoma’s Earthquakes Strongly Linked to Wastewater Injection Depth, Finds Study

A huge increase in the number of man-made earthquakes in Oklahoma, USA, is strongly linked to the depth at which wastewater from the oil and gas industry is injected into the ground, according to a new study involving the University of Southampton.

Further Reducing Injections of Oilfield Wastewater Underground Can Prevent Larger Earthquakes

The new study shows that locations that experienced earthquakes are tied in proximity and timeliness to mass waste water injection sites. Further, the study indicates that tracking annual data on the injection well locations can help predict how corresponding earthquake activity will change. This new finding builds on previous studies showing that earthquake activity increases when wastewater injections increase.

A Chinese team of researchers awarded this year’s prestigious Gordon Bell prize for simulating the devastating 1976 earthquake in Tangshan, China, used an open-source code developed by researchers at the San Diego Supercomputer Center at UC San Diego and San Diego State University with support from the Southern California Earthquake Center.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown for the first time that dark fiber – the vast network of unused fiber-optic cables installed throughout the country and the world – can be used as sensors for detecting earthquakes, the presence of groundwater, changes in permafrost conditions, and a variety of other subsurface activity.

Analysis to evaluate the onset of global instability under tension/compression load shows that the onset of buckling can be identified using either a proposed buckling theory or computer simulations.
