Atmospheric gravity waves drive winds, temperature and chemical composition in the middle and upper atmosphere, but not enough is known about those that occur at higher altitudes. Now though, an ...

SWOT observations of the tsunami wave field offshore Kamchatka about one hour after the earthquake covering the two parallel diagonal lines cutting across the image. The measurements allowed the ...

Surface Acoustic Wave (SAW) devices represent a class of sensors that exploit the propagation of acoustic waves through piezoelectric substrates to detect changes in mechanical and environmental ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network of Global ...

Researchers develop a proof-of-concept millimeter wave radar sensor that can detect extremely small vibrations and movements. Researchers at the University of California, Davis, have developed a proof ...

BILLINGS — The installation of powerful seismic sensors in Yellowstone National Park over the past four years to track the area’s sleeping volcano has incidentally provided insight into rhythmic wave ...

This prototype millimeter-wave radar sensor developed at UC Davis is capable of measuring extremely small vibrations and movements while being energy-efficient and cheap to produce. Researchers at the ...
