Hi David,

       I had to sign on, but there are three articles about earthquake / 
tsunami / alert warning / systems. They seem to have the most incompetent 
registration system that I have yet encountered. And you are prevented from 
complaining since the validation display text is not recognised!
       With some thousands of sensors around Japan, it is practicable to 
sense the first fast P wave. This could give some seconds warning before the 
damaging surface waves reach you - maybe enough to dive under the table!
       Regards,

       Chris Chapman
