Is the device near the upper right of this pic:
http://sites.google.com/site/am909geo/osm-1/TsunamiAlert.jpg a tsunami
warning siren? I've seen a number of similar devices in coastal areas. This
particular one is at 33.4993, -117.67656.

Hi Alan,
It's a siren, they are pretty common in Denmark.
In Denmark they are used as part of a general warning system, I don't
know the use of the sirens in your area.
Best regards,

Similar things exist in various places for tornado
I just found a site that lists the location of their tornado warning sirens...

Their larger map doesn't look very nice, maybe someone could do up a

Here in the US they are called civil defense sirens and depending on
the area and the tones that they emit they can indicate any number of
threats to the public. Of course their first use was during WWII to
warn of air raids and then nuclear attack during the cold war. Now
they are probably best
