Scientists have successfully developed and tested a high-tech device that can detect the small movements and changes in the Earth's seafloor -- often a precursor to deadly natural hazards, like earthquakes, volcanoes and tsunamis. The shallow water buoy was installed off Egmont Key in the Gulf of Mexico last year, and has been producing data on the three-dimensional motion of the sea floor, according to the researchers from the University of South Florida (USF) in the US. The system will be able to detect small changes in the stress and strain of the Earth's crust, the researchers noted. The patent-pending seafloor geodesy system is an anchored spar buoy topped by high precision global positioning system (GPS), they said. The buoy' orientation is measured using a digital compass that provides heading, pitch, and roll information -- helping to capture the crucial side-to-side motion of the Earth that can be diagnostic of major tsunami-producing earthquakes, Dixon said. While … [Read more...] about Scientists develop device to improve earthquake, tsunami forecast

In a decision handed down Wednesday by a three-judge panel of the First Appellate District Court of Appeal, the court went against a 2013 United States Supreme Court decision known as Maryland v. King. That case found that a similar DNA law in Maryland was a valid form of police identification of suspects, analogous to fingerprinting and photographing. … [Read more...] about Court strikes California law requiring DNA collection for felony arrestees
Some natural infrasound signals may be clearest in the atmosphere, noted Omar Marcillo, a geophysicist at Los Alamos National Laboratory in New Mexico, who was not involved in the study. The atmosphere refracts some sound waves away from the ground, so some infrasound signals may never reach the ground. In the sky, there is also less interference from human noise. … [Read more...] about Eerie ‘X-Files’ Sounds Recorded from the Edge of Space
Before last night’s accident, the company said it was about to conduct the very first hot fire test of the core section of its Alpha rocket, which entails holding down the vehicle on a test stand and igniting the engines. The Burnet County Sheriff’s Office said it was informed of a “possible explosion” at 7:24PM ET, though Firefly later claimed the accident was a “small fire.” Video of the event posted by a local reporter at KXAN shows the test stand going up in flames. … [Read more...] about Fire breaks out during test of Firefly Aerospace’s rocket in Texas
Geoff Wade, Senior Research Fellow at the University of Singapore's Asia Research Institute, echoed her sentiment. "The map is an 18th-century copy of a European map, as evidenced by the two hemispheres depicted, the continents shown and the non-maritime detailed [sic] depicted," he wrote recently to a group of maritime scholars. … [Read more...] about Map Fuels Debate: Did Chinese Sail to New World First?
