Tillamook County has decided to remove their Tsunami sirens.. And I wonder what people think about this.. in fact I even found a Facebook group who disagree with the whole idea… http://www.facebook.com/SOSTillamookCounty
What do you think?
It seems to me that in an emergency you should have MORE ways to notify the public.. And that folks who may be sleeping, or may not have access to telephones may not get the message.. There is another point here.. Many people assume that the Tsunami threat will be evident because of the preceding earthquake but this fails to take into account the very real possibility of tsunami being generated from a distant even.. Much like is thought with the megatsunami event which have been in the past triggered not only by earthquakes but also by Volcanic Eruptions and even distant mega land slides..
Personally I think that limiting the contact possibilities is a horrible idea.. But who am I anyway..

Next time a tsunami from foreign shores is headed our way, you might hear the warning in Tillamook County by phone, over public address systems from police or fire agencies or even from the sky.
But come January 2013, you will not hear it in the wail of a siren.
After more than a year of discussion, the county has decided there are better ways of reaching the public. And Tillamook County is not the only coastal county with that idea. Emergency managers are increasingly looking to phone, email, text notifications, social media, the Civil Air Patrol and good old-fashioned personal contact.
“It’s WWI and WWII technology,” said Gordon McCraw, director of Tillamook County emergency management, of the sirens. “It’s outlived its usefulness. With all the new technology, we are now able to deliver a specific, targeted message to residents and visitors that informs them about the threat and recommends actions, and in more than one language.”
Tillamook County began evaluating the warning system after cities within the county asked commissioners to take over maintenance and responsibility for the tsunami sirens.
It is generally accepted that in a local event, such as the one anticipated when the Cascadia Subduction Zone ruptures, the three to five minutes of violent shaking will destroy power lines, rendering the sirens silent.
But the sirens have been considered a key warning device for tsunamis triggered by distant earthquakes, such as the one that reached Oregon and Northern California shores after the 9.0-magnitude earthquake in Japan in March 2011.
Tillamook County commissioners decided their first action should be to make sure the sirens were where they were most needed. So they turned to the state Department of Geology and Mineral Industries for new inundation maps and found quite the surprise.
“We said, ‘Whoa,'” McCraw said. “We’re not nearly as threatened from a distant tsunami as we thought. New maps show a distant event would only affect the immediate coastline equal to the astronomical high-tide marks. A distant tsunami would not be enough to threaten anything but people on the beach.
