I'm not sure how many of you are aware of the CERT program (Community =
Emergency Response Team) which was developed in 1985 by the Los Angeles =
City Fire Department in 1985 to train ordinary citizens to be first =
responders in a major disaster.  The program was later adopted by FEMA =
(1993) and the training materials are available online at =
http://www.citizencorps.gov/cert/index.shtm

In their training manual they discuss various earthquake myths.  One of =
them perplexes me and I would love to hear from anyone who can explain =
this.  Below is the material in their training manual.  My questions is =
what are the "first low frequency waves of an earthquake" that come =
PRIOR to the primary and secondary waves?  Are they talking about EM or =
non seismic waves?

Their training guide.....

      Myth:
     Animals can sense earthquakes and give advance warning.

      Fact:
     Animals may be able to sense the first low-frequency waves of an =
earthquake that occur deep within the Earth, but the damage-causing =
primary and secondary waves follow just seconds behind.  Animals do not =
