The quake happened at 2:46PM local time.
The wave travels at 500 MPH.
So for Tokyo, the time was half hour from quake to landfall.
For the places seen destroyed, the quake was 80 miles off the coast. For San Diego, think Catalina island.
So Sendai would have been hit in under 10 minutes of the quake.
10 minutes… –edit—
I stand corrected, apparently time lag for nearest points was 10-30 minutes. Sendai airport, (distance unknown) was 1 hour.
The wave slows to approximately 45MPH with shorefall.
