Probably a DSC mayday. Good thing you didn't respond!

Yesterday my ICOM vhf (which has DSC capability) would suddenly change to
channel 16 and emit a very loud ambulance siren type sound from the
speaker.
The volume of the sound was not controllable and be canceled by changeing
channels or pushing the DSC button.This happened quite a few times. Today
I
tested the unit by leaving it on for a good while , checks OK. So could
this
be caused by solar flares?

Actually, there was no transmission, this happened about every thirty
minutes for over 12 hours. Surely no emergency would last that long or they
would figure out what they wanted to say? I did recieve a few coast guard
pan-pan's on my other non DSC radio at various times that did not coincide
with these alarms.
