### If a very huge Earthquake occured anywhere on Earth could waves emerge to come together again on the opposite side?

It is called "antipodal focusing". See for example Antipodal focusing of seismic waves observed with the USArray. We present an analysis of the M-w = 5.3 earthquake that occurred in the Southeast ...

### Why are there waves in seas towards shore - even in night?

Ocean waves (and also in mediterranean type seas and larger lakes, but on a smaller scale) are generated by two processes: locally generated waves ("wind waves"), which follow the direction of the ...

### Why do Tsunamis travel slower than sound?

Tsunamis and sound waves are different types of wave - one is a transverse wave and the other is a longitudinal one. Let's look at the factors that influence the speed of each one. Tsunami - ...

### What causes waves to form the characteristic "breaking" shape as they approach the shoreline?

One thing that I would add is a discussion of a physical parameter that is a simple measure of whether a wave is going to topple or not. The Froude number is defined as the ratio of the maximum ...

### How to distinguish P, S, Love, and Rayleigh waves in a seismogram?

You can automatically detect the P and S waves for an event but I don't know of a way to automatically extract the Rayleigh and Love waves directly from the seismograms. As @kwinkunks points out ...

### How do Kelvin waves determine surface temperature variations?

Coastal trapped Kelvin waves are important processes contributing to variability in the sea surface height and temperature near the coast. Field studies have measured large temperature fluctuations ...

### Should one extract wavelet from seismic or well log for the generation of synthetic traces?

Seismic, but... There are lots of ways of estimating wavelets. None of them rely on well logs alone, because they don't contain any information about the wavelet. Some methods are purely statistical, ...
