Sending multiple alerts (or more "cancel" alerts) after the initial alert 
tends to interfere with news reports covering or correcting the story.

Sending more EAS alerts tends to just make things worse.

Instead....

1. If using IPAWS, use the "cancel" function to cancel the message, do not 
send a new alert message trying to correct the previous message.  Check 
with your IPAWS CAP vendor how to use the cancel function.  The cancel 
function is NOT the same as sending a new message.

2. If using classic EAS, do NOT send more EAS messages trying to correct 
the previous message.

3. Notify all news media using non-EAS channels, such as email blast, 
twitter, etc the alert was false or accidentially activated.  Journalists 
are very good at correcting the story and keeping the public informed.
EAS is a very loud wake-up bell. Journalists will quickly respond.

4. If the public is concerned about an alert, they will check other news 
stations and news web sites for more information.  Most of the time, if 
the message isn't repeated and there are no other alert indications; the 
public just ignores a single erronous alert.

The public doesn't panic about alert, they look for confirmation sources.
