Dale,

How do you differentiate the "T" and the Love and Raleigh waves.

The recent M7.8 New Zealand EQ produced " T " waves which showed up very
strongly on my geophone.

"T" phase & is seen for big events - it is transmitted through the ocean
water, rather than through the rock below  - hence it is slower  - only seen
for events under oceans ( & probably have to be shallow as well)
