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.
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 ...
Will the 2014 El Nino be like 1997?
Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet ...
Climate change likely to bring fewer big waves
A warmer climate is likely to result in fewer large waves along Australia's central east coast, according to Bureau of Meteorology research that predicts a decline in the frequency of storms known as East C ...
Seafloor carpet catches waves to generate energy
(Phys.org) —What do champion surfers who gathered at last week's Mavericks Invitational have in common with a UC Berkeley engineer? They all are looking to harness the power of big ocean waves.
Is there an ocean beneath our feet?
(Phys.org) —Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth's oceans to the upper mantle than previously thought.
