Three studies now published in the open-access journal The Seismic Record offer an initial look at the February 6, 2023 earthquakes in south-central Türkiye and northwestern Syria, including how, where, and how fast the earthquakes ruptured and how they combined as a “devastating doublet” to produce damaging ground shaking.
An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications.
Sensors that detect changes in atmospheric pressure due to ground shaking can also obtain data about large earthquakes and explosions that exceed the upper limit of many seismometers, according to new research.
Title 42, the United States pandemic rule that had been used to immediately deport hundreds of thousands of migrants who crossed the border illegally over the last three years, has expired. Those migrants will have the opportunity to apply for asylum. President Biden's new rules to replace Title 42 are facing legal challenges. Border crossings have already risen sharply, as many migrants attempt to cross before the measure expires on Thursday night. Some have said they worry about tighter controls and uncertainty ahead. Immigration is once again a major focus of the media as we examine the humanitarian, political, and public health issues migrants must go through.
Geoscientists have detected specific gases being released from fractured rocks in real time after a series of small chemical explosions set underground. This fundamental research, led by Sandia National Laboratories geoscientist Steve Bauer, could one day improve the prediction of earthquakes or detection of underground explosions.
An early warning system that quickly classifies submarine earthquakes and determines the risk of tsunami events has been developed by scientists at Cardiff University.
In Physics of Fluids, researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries information about the tectonic event and travels significantly faster than tsunami waves. The computational model triangulates the source of the earthquake and AI algorithms classify its slip type and magnitude. It then calculates important properties like effective length and width, uplift speed, and duration, which dictate the size of the tsunami.
Researcher will discuss the study which involved a sleeping aid known as suvorexant that is already approved by the Food and Drug Administration (FDA) for insomnia, hints at the potential of sleep medications to slow or stop the progression of Alzheimer’s disease.
Researchers know a lot about Turkey’s next major earthquake. They can pinpoint the probable epicenter, estimate its strength and see the spatial footprint of where damage is most likely to occur.
By invading new environments, some alien species have caused disastrous consequences for local species and ecosystems, as well as for human activities – damage to infrastructure, crops, forest plantations, fishing yields, health and tourism. The areas affected are multiple and the damage is costly.
In the wake of the 2020-2021 Southwest Puerto Rico earthquake sequence, researchers asked emergency responders and residents in affected communities about the information they needed to prepare for the next earthquake.
Ocean-based hydrophones in the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO)’s seismic-acoustic monitoring network could provide a better look at how ocean temperatures are changing over time, according to a presentation at the Seismological Society of America (SSA)’s 2023 Annual Meeting.
Seismic arrays deployed in California’s Long Beach and Seal Beach areas detected more than a thousand tiny earthquakes over eight months, many of them located at surprisingly shallow depths of less than two kilometers below the surface.
The country of Turkey is still reeling from a 7.8 and a 7.5 magnitude earthquake and thousands of aftershocks that occurred in February, causing widespread destruction to infrastructure and human life. To aid response and recovery efforts, two researchers from the University of Alabama in Huntsville (UAH) Earth System Science Center (ESSC) are using Earth observations to help those on the ground in Turkey make informed decisions.
At Idaho National Laboratory, computational scientists use INL’s supercomputers to perform “virtual experiments” to accomplish research that couldn’t be done by conventional means. While supercomputing can’t replace traditional experiments, supercomputing is an essential component of all modern scientific discoveries and advancements.
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.
