The Northwest Pacific coast of Mexico is an area struck by large earthquakes and tsunamis as a result of the interaction of two tectonic plates. However, to date, the structure of the continental margin and, therefore, the causes behind the generation of these natural hazards were unknown.
The claim a Dutch researcher predicted the February earthquake in Turkey and Syria would happen three days before it occurred is misleading. Despite the accuracy of his prediction, scientists cannot predict when and where an earthquake will occur.
Residents of Southern Turkey were again jolted by a new earthquake Monday, this trembler reported by the U.S. Geology Survey (USGS) as 6.3 in magnitude. News reports state that scores of buildings that were damaged in powerful quakes on February 6 have been further damaged or outright collapsed. Virginia Tech’s Robert Weiss, who studies natural hazards, calls the devastating trio of earthquake “unusual,” but not “impossible.
The earthquakes in Turkey and Syria killed over 45,000 people and decimated large areas. The shockingly high number of fatalities raises the question of whether infrastructure issues are to blame. Roberto Leon, a professor of civil and environmental engineering at Virginia Tech, said there are several reasons for the large number of collapses, leading to mass casualties: Poor enforcement of existing codes (modern codes instituted after the 1999 Izmit earthquake) Grandfathering of older, deficient structures and not requiring their retrofit (structures built before 1999) Poor construction practices (i.
Renaissance polymath Leonard da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force. When two objects are pressed together twice as hard, friction doubles.
A magnitude 7.8 earthquake struck south central Turkey near the Turkey/Syria border on February 6. Within 11 minutes, a magnitude 6.7 aftershock convulsed a region 60 miles north. So far, more than 35,000 people have died, surpassing Japan’s Fukushima earthquake disaster in March 2011. Scientists at the U.S. Geological Survey (USGS) said an earthquake of this magnitude is rare anywhere in the world Husam Najm, a professor of civil and environmental engineering in the Rutgers School of Engineering who specializes in the study of various advanced concrete materials and the design of novel forms of concrete bridges, discusses the unfolding tragedy, its causes and efforts to design earthquake-resistant structures to stave off such catastrophic losses in the future.
Modeling the effects of earthquakes on homes, businesses, and infrastructure is about to get a lot easier, thanks to advanced simulations performed on the world's fastest supercomputers.
University of Miami College of Engineering faculty members Nurcin Celik and Derin Ural lived through the 1999 temblor that struck near the Turkish city of Izmit. They stand ready to offer their expertise in the aftermath of Monday’s disaster.
Sinan Akçiz, assistant professor of geological sciences at Cal State Fullerton, turned his Introduction to Geology class on Monday into a real-life lesson about earthquakes and the devastation taking place in his native country, Turkey.
The false alert, the first of its kind in the United States, offered a unique opportunity to learn more about the importance of early warning earthquake and post-alert messaging.
When the rigid plates that make up the Earth’s lithosphere brush against one another, they often form visible boundaries, known as faults, on the planet’s surface. Strike-slip faults, such as the San Andreas Fault in California or the Denali Fault in Alaska, are among the most well-known and capable of seriously powerful seismic activity.
When it comes to predicting disasters brought on by extreme events (think earthquakes, pandemics or “rogue waves” that could destroy coastal structures), computational modeling faces an almost insurmountable challenge: Statistically speaking, these events are so rare that there’s just not enough data on them to use predictive models to accurately forecast when they’ll happen next.
A $500,000 grant from the National Science Foundation will spur The University of Texas at El Paso’s efforts to help underserved communities across the nation become more resilient to earthquakes.
Satellite observations have revealed that weak seismic ground shaking can trigger powerful landslide acceleration – even several years after a significant earthquake.
Caltech Hall, a 55-year-old nine-story reinforced concrete building on the Caltech campus, has been getting structurally stiffer over the past 20 years, according to a new report published in The Seismic Record.
One natural disaster can knock out electric service to millions. A new study suggests that back-to-back disasters could cause catastrophic damage, but the research also identifies new ways to monitor and maintain power grids.
An artificial-intelligence approach borrowed from natural-language processing — much like language translation and autofill for text on your smart phone — can predict future fault friction and the next failure time with high resolution in laboratory earthquakes,. The technique, applying AI to the fault’s acoustic signals, advances previous work and goes beyond by predicting aspects of the future state of the fault’s physical system.
66 million years ago, a 10-kilometer asteroid hit Earth, triggering the extinction of the dinosaurs. New evidence suggests that the Chicxulub impact also triggered an earthquake so massive that it shook the planet for weeks to months after the collision.
Scientists who drilled deeper into an undersea earthquake fault than ever before have found that the tectonic stress in Japan’s Nankai subduction zone is less than expected, according to a study from researchers at The University of Texas at Austin.
By: Kathleen Haughney | Published: September 19, 2022 | 4:01 pm | SHARE: Mexico is dealing with the fallout of a powerful 7.6 magnitude earthquake that occurred near the Pacific coast on the anniversary of two previous tremors. Earthquakes occurred on Sept. 19 in both 1985 and 2017 in Mexico, killing thousands of people.Florida State University Professor of Geology James Tull is available to speak with reporters about the effects of the earthquake and the geology behind this catastrophic event.
A new experimental facility that replicates realistic earthquakes in the laboratory, paired with the world’s fastest supercomputers, will help scientists and engineers build and retrofit shake-resilient buildings and infrastructure across the U.S.
Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas.
A new research center is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January created an initial wave 90 metres high – almost the height of the Statue of Liberty (93m)
Now, researchers say ubiquitous evidence for ongoing geological carbon sequestration in mantle rocks in the creeping sections of the SAF is one underlying cause of aseismic creep along a roughly 150 kilometer-long SAF segment between San Juan Bautista and Parkfield, California, and along several other fault segments.
California’s McKinney Fire grew to become the state’s largest fire so far this year. The risk of wildfire is rising globally due to climate change. Below are some of the latest articles that have been added to the Wildfires channel on Newswise.
