Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

THE velocity of longitudinal waves in the earth increases with depth down to the core, at a depth of about 2,900 km., where there is a discontinuous drop from 13·7 km. to about 8 km. per sec.

It just shows that the earthquake was a shallow one. Suppose a train is coming, as it gets closer, the sound gets louder. In the same way, when an earthquake occurs, seismic waves travel through the ...

This course gives a basis for understanding how elastic waves, generated by earthquakes or controlled sources, propagate through the Earth and thus provide information about its interior. Students ...

A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents ...

I’m now funded by Research Ireland on a Government of Ireland postdoctoral research fellowship to look at how machine learning techniques could help us to apply seismic data in new ways.

AM, a 4.0 earthquake hit Delhi and the surrounding areas. Residents moved out of their houses due to the rumbling sound and massive jolt. The epicenter of the quake was Delhi’ Durgabai Deshmukh ...

From exploding the smartphone market with the iPhone to single-handedly killing the headphone jack, Apple is one of only a ...

In fact, that eruption produced two signals that are evident in the Yellowstone seismic record. The first signal is the direct P-wave (seismic phase) that traveled through the earth from the eruption ...

Abstract: Because of the viscoelastic properties of the Earth, seismic waves experience attenuation during propagation, resulting in decreased amplitude and phase distortion, ultimately reducing ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges Sara Hashemi Daily Correspondent Deep at the ...
