If you live on or near the west coast of North America you likely had a stressful hour or so this past evening.
This is because a tsunami warning had been issued for all coastal areas between the California/Mexican border and Alaska.
We were watching a Seattle TV station at the time, it was about 8:15 when they interrupted the show we were watching to inform us of the tsunami warning. But there was very few details other than an earthquake happened off the coast of California and there was a warning issued. We had no idea who was affected or for how long.
So I decided to see what the net had for information.
