Sound waves may be able to trigger earlier tsunami warnings

Can sound waves improve tsunami warning systems?ERNESTO BENAVIDES/AFP/Getty Images By Mika McKinnon When a tsunami is barreling towards a coastline, the only way to stay safe is to flee to higher ground. But even when people are far enough away from the start of the tsunami to have hours of warning, no one really knows […]

Rogue waves can move rocks weighing hundreds of tonnesrock on coast Noel Moore/Alamy Stock Photo By Lucas Joel MONSTROUS oceanic waves are able to transport boulders weighing hundreds of tonnes. The finding helps explain how huge rocks end up atop high cliffs. It also implies that storm waves, and other rogue waves, can be more […]

Waves in lakes make waves in the Earth

Waves in lakes make waves in the Earth

Beneath the peaceful rolling waves of a lake is a rumble, imperceptible to all but seismometers, that ripples into the earth like the waves ripple along the shore. Scientists report that these small seismic signals can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over […]

LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

For the first time, scientists have directly detected gravitational waves–ripples in space-time–in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been observed in both gravitational waves and light. The discovery was made using the U.S.-based Laser Interferometer Gravitational-Wave Observatory; the Europe-based Virgo […]
