… that its magnitude can be used to estimate the tsunami’s wave height. How much earlier the magnetic field arrives … field, similar to that of the beginning of a seismic wave, can be used for the purpose of early tsunami warning. … magnetic field is so sensitive that even a wave height of a few centimeters can be detected. “They did …
… speed of these disturbances and found the electromagnetic wave along the magnetic field lines travelled at 1000 … per second. This was far faster than the air pressure wave, which traveled at the speed of sound (a comparatively … of the ionospheric disturbance caused by the air pressure wave about three hours before the pressure wave originating …
… or even ice and snow. In this study, three nonlinear wave regimes are identified depending on the Froude … non-linear transition waves at small Froude number. The wave amplitude relative to the water depth increases with … or decreasing function of Froude number. Two of these wave regimes are rationalized by considering that the …
… landslide. Researchers come up with models to predict wave runup onto the shore following a landslide on an … challenging part is to account for the nonlinear nature of wave runup and rundown, as well as the complex shelf zone … on shallow-water equations to describe both surface wave generation and landslide movement. Despite a number of …
… On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the … the Great Lakes caused by an atmospheric inertia-gravity wave. An atmospheric inertia-gravity wave is a wave of air that can run from 6 to 60 miles long …
… wide – much larger than can be simulated in a traditional wave tank. “This is the first time anything like this has … soil, with gates to allow for flow simulating a tsunami wave. “We’re trying to mimic the entire process of a tsunami … drawing back,” Mason said. “If you’re putting soil in a wave flume to try to do that, it gets really, really …
… is remarkably sensitive, he noted, able to detect seismic wave velocities as small as tens of nanometers per second. … seismologists usually have to wait for the seismic wave data to reach distant stations before it can be … from global tide gauges and buoys that detect a tsunami wave in the open ocean, to determine whether a tsunami …

… issued, but by then, it was too late. In some places the wave had arrived just one minute earlier , swallowing coastal … “The magnetic field is generated like a circle around the [wave],” explains Lin, “so we can detect it earlier.” … adding that the fields can also be used to estimate the wave’s height before it strikes. “This means that we not only …
