ANCHORAGE, Alaska (AP) – A National Weather Service worker
inadvertently sent a tsunami warning to Alaska radio and television
stations Monday as employees were reviewing procedures to issue such
alerts.
Officials suspect the warning was transmitted when someone
accidentally double-clicked the cancel button with their computer’s
mouse, said Sam Albanese, warning co-ordination meteorologist for the
National Weather Service’s Anchorage office.
After the cancel button is clicked once, the screen disappears. But
once it goes away, the screen behind it has the transmit button in the
same location as the cancel button.
Rapidly clicking the mouse twice may have unintentionally sent the
tsunami warning since the computer program did not have a confirmation
screen to send it, Albanese said.
"There is no confirmation when that transmit is hit, it just starts to transmit," Albanese said.
Officials have initiated procedures to make sure the error is not repeated.
"We’re working with programmers to make sure there is a fail-safe
put into the program so we don’t transmit something inadvertently," he
said.
The message, which went directly from the weather service to Alaska
broadcasters, only contained a tsunami warning header. If it were a
real emergency, meteorologists would have added actual text into the
body of the message, outlining which areas of the state would have been
covered by the warning.
The Weather Service later sent a correction.
Media outlets across the state were taken by surprise with the 8:53
a.m. warning. The weather service received phone calls from stations
from Fairbanks to Juneau when the tsunami warning was not followed by
any further information.
Television stations also received calls after the tsunami warning crawled across their screens.
"Every phone in the place started ringing," said Ed Bennett,
assignment editor for KTUU television in Anchorage. "We had between 30
to 50 phones calls in the newsroom and an equal number at the front
office in a 15 minute period."
