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.
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.

Last week’s magnitude 7.1 earthquake near Puebla, Mexico, killed and injured hundreds of people and caused widespread damage to structures in Mexico City. Civil engineering professor Clint Wood, a geotechnical-engineering specialist, will travel to Mexico City this week to study the earthquake’s impact on buildings and infrastructure in the area.
Disaster relief workers searching for earthquake survivors in Mexico City are using technology developed by NASA's Jet Propulsion Laboratory and the Department of Homeland Security's Science and Technology Directorate.
Oceanographers and a Seattle engineering company are testing a simple technique to track seafloor movement in earthquake-prone coastal areas.
East Africa may be a long way from the Crescent City but it is top of mind for Tulane PhD student Sarah Oliva, who is studying data from volcanoes and earthquakes in that region. Her goal is a better understanding of how a 3,000-kilometer long deep valley– the East African rift system— formed. Ultimately, she hopes her research will enable her to work with scientists and help governments protect residents living near the rift.
Using a fleet of airplanes, ships and intrepid scientists, Cornell is leading the largest single deployment of seismometers along the Alaskan Peninsula – a $4.5 million endeavor that geologists from across the country hope will solve long-standing mysteries about the region and the planet.
By listening to the acoustic signal emitted by a laboratory-created earthquake, a computer science approach using machine learning can predict the time remaining before the fault fails.
Wastewater injection rates in Oklahoma have declined recently because of regulatory actions and market forces, but seismologists say that has not yet significantly reduced the risk of potentially damaging earthquakes.
The stresses released by human-induced and naturally occurring earthquakes in the central United States are in many cases indistinguishable, meaning that existing tools to predict shaking damage can be applied to both types.
-- A two-story wooden structure endured four different earthquake simulations on July 14, 2017 on the world’s largest outdoor shake table here in San Diego. And it’s still standing before more tests in the coming weeks. The goal of the tests is to gather enough data to design wood buildings as tall as 20 stories that do not suffer significant damage during large earthquakes. That is, not only can occupants leave the building unharmed, but they can come back and resume living in the building shortly after a temblor.
Earthquakes and explosions damage thousands of structures worldwide each year, destroying countless lives in their wake, but a team of researchers at Penn State is examining a completely new way of safeguarding key infrastructure, thanks to a $50,000 Multidisciplinary Research Seed Grant provided by the College of Engineering.
An international team of scientists has found evidence suggesting the dehydration of minerals deep below the ocean floor influenced the severity of the Sumatra earthquake, which took place on December 26, 2004.
Experiments at Berkeley Lab’s Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.
West Virginia University professor Hota GangaRao and Praveen Majjigapu, a Ph.D. student in civil engineering, have developed a system that will increase the strength and endurance of structures in earthquakes, hurricanes, tornadoes and other large blasts, helping communities prevent catastrophe. The system is also beneficial for repairing historic or aging structures.
Using radioactive elements trapped in crystallized, cream-colored “veins” in New Mexican rock, geologists have peered back in time more than 400,000 years to illuminate a record of earthquakes along the Loma Blanca fault in the Rio Grande rift. It is the longest record of earthquakes ever documented on a fault.
An algorithm for stock prices can be used with GPS data to automatically detect slow-slip earthquakes at a single station, offering a new way to monitor seismic activity.
Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world’s fastest supercomputers, a team led by Jeroen Tromp of Princeton University is creating a detailed 3-D picture of Earth’s interior. Currently, the team is focused on imaging the entire globe from the surface to the core–mantle boundary, a depth of 1,800 miles.
When geologists went in search for evidence of ancient tsunamis along Southern California’s coastal wetlands, they found something else. Their discoveries have implications for seismic hazard and risk assessment in coastal Southern California.
The Newport-Inglewood and Rose Canyon faults had been considered separate systems but a new study shows that they are actually one continuous fault system running from San Diego Bay to Seal Beach in Orange County, then on land through the Los Angeles basin.
Researchers at the San Diego Supercomputer Center (SDSC) at the University of California San Diego have developed a new seismic software package with Intel Corporation that has enabled the fastest seismic simulation to-date, as the two organizations collaborate on ways to better predict ground motions to save lives and minimize property damage.
A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth.
When Superstorm Sandy lashed New Jersey in 2012, Narayan B. Mandayam lost power in his East Brunswick home for five days.
