Water waves exhibit negative gravity near a periodic array of buoys
'Virtual earthquakes' used to forecast Los Angeles quake risk
Stanford scientists are using weak vibrations generated by the Earth's oceans to produce "virtual earthquakes" that can be used to predict the ground movement and shaking hazard to buildings from real quakes.
Scotland to deploy largest hydro-electric wave energy farm to date (w/ video)
Chips that can steer light
If you want to create a moving light source, you have a few possibilities. One is to mount a light emitter in some kind of mechanical housing—the approach used in, say, theatrical spotlights, which stagehands ...
Magma in mantle has deep impact: Study suggests rocks melt at a greater depth than once thought
Magma forms far deeper than geologists previously thought, according to new research at Rice University.
What caused a giant arrow-shaped cloud on Saturn's moon Titan?
(PhysOrg.com) -- Why does Titan, Saturn's largest moon, have what looks like an enormous white arrow about the size of Texas on its surface?
World's biggest Wave Hub installed off UK coast
Triple whammy triggered Samoa tsunami (Update 2)
A tsunami that hit the Pacific islands of Samoa and Tonga last year was generated by three earthquakes unleashed by a seismic mechanism that has never been observed before, scientists said on Wednesday.
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
Better forecasts for sea ice under climate change
University of Adelaide-led research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating.
Small islands may amplify tsunamis
Small islands, long thought to be natural tsunami barriers for coast-dwellers, may in fact amplify the waves they are supposed to break, researchers warned Wednesday.
Studies in laser physics help understand rogue waves
(Phys.org) —University of Auckland physicist Dr Miro Erkintalo is part of an international team investigating how lasers and optical fibres can be used to understand freakishly large waves on the ocean.
Huge waves measured for first time in Arctic Ocean
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle ...
Directionality of crystal elasticity offers explanation for variable seismic character of the inner Earth
Seismic studies enable geoscientists to map the Earth's internal structure. Certain seismic observations, however, remain puzzling, such as the unexpected spatial variability in the speed of seismic waves ...
