My condolences to Chile but these tsunami things are usually just overreaction, sensationalism and people trying to cover their ass after the southeast Asian tsunami. They put us under tsunami warnings here all the time (and I guess we are right now). I may be proven wrong, hope I'm not though.

No one cares about the industrialized nations.
UPDATE: I was right.
Ventura County, CA saw a 3 ft water rise.
Also, there was a tsunami, but it wasn't a large as they thought it would be.
The warning was hyped because there was a deadly tsunami in Hawaii in 1960 that came from an earthquake in Chile, but there was a lot less warning for it. As a result, this one was warned to death.
They put the warning up based not solely on the fact that there was an earthquake, but what type and also from buoy observations, as well as observations from other islands closer to the earthquake epicenter (which did see a significant sea-level change).
You weren't under a warning, but you were under a tsunami advisory.

Looking from these maps, though, it seems that the impacts were too small to be of any interest except for local, and it probably was a slip event (earth moving sideways along a fault), which don't generate tsunamis.
Just because there was a 7.7 Earthquake in or near Japan, doesnt mean there will be a Tsunami. A Tsunami only forms after a certain type of earthquake, where Vertical Plate slip is involved.
Tsunamis occur when there is a sudden and large displacement of water. With earthquakes, it's with the sudden upward thrust of the seafloor, and chiefly in subduction zones like near Chile and Indonesia where the seafloor moves vertically (one plate slips under another). Slip faults like the San Andreas fault don't create tsunamis because the earth only moves horizontally along the fault.
