Alaska residents get false tsunami warning on TV, radio
JUNEAU, Alaska — Many Alaska residents were mistakenly warned on TV and on the radio Friday morning of a tsunami threat along the West Coast of the United States, from San Diego to Alaska’s Aleutian islands.
The alert said at the end of a nearly two-minute long message that it was a test. But not all listeners and viewers received that information, officials said.
The National Tsunami Warning Center said there was no threat. It said the message was a routine test sent at about 7 a.m.
Susan Buchanan, a National Weather Service spokeswoman, said the centre’s test message was properly coded but somehow re-transmitted in an abbreviated format. That stripped the test coding and caused activation of the Emergency Alert System that sends messages to TV and radio stations.
