Morning from New Zealand
I'm one of those WHAT,WHERE & HOW people I don't know at your talking about 

I've got a question in your Email you said that  you I recieved a 
Teleseismic event from New Zealand

What is a Teleseismic event?
Where did the Teleseimic event happen?
How long was the Teleseimic Event?

How did you or they measuring the Hz rates?  are you talking about  radio 
noise your measuring or Wind or what?

I understand and know "tele" means visial affect and seismic is the resolt 
of waves radiating outwards from a centre of force release eg: a stone 
thrown into water generates a seismic affect
