It may be a day or two before we actually get the real measurement, I believe what caused the moderate sized tsunami to hit Hawaii back in the 60’s at Hilo was the result of an undersea mountain collapse off the coast of Peru.

Please forgive my dumb question...can planes observe a wave coming way before it arrives?
