Due to increase Sun activity more potent quakes are a possibility this week. Four 8.0 have been suggested by scientist. 7.8, 7.1 have recently hit. Tsunami could be 100-150 feet in height. Tsunami's wrap around bays then slam into them. Unless you are above the height of a wave then your chances are slim.
Being prepared is what is needed. Warnings can be off target. Just be Safe...
