All earthquakes do not cause tsunamis but many do. When you hear that an earthquake occurred, stand by for a tsunami emergency message.
An earthquake in your area is a natural tsunami warning. Do not stay in low-lying coastal area after a strong earthquake has been felt.
A tsunami is not a single wave but a series of waves. Stay out of danger areas until an “all-clear” is issued by a competent authority.
Approaching tsunamis are sometimes proceeded by a noticeable rise or fall of coastal water. This is nature’s tsunami warning and should be heeded.
A small tsunami at one point on the shore can be few miles away. Don’t let the modest size of one make you lose respect for all.
All warnings to the public must be taken very seriously, even if some are for non-destructive events. The tsunami of May, 1960 killed 61 people in Hilo, Hawaii because some thought it was just another false alarm.
All tsunamis like hurricanes are potentially dangerous though they may not damage every coastline they strike.
Never go down to the shore to watch for a tsunami. When you can see the wave you are too close to escape it. Never try to surf a tsunami; most tsunamis are like a flash flood full of debris and they do not curl or break like surfing waves.
During a tsunami local civil defense, police and other emergency organizations will try to save your life. Give them your fullest cooperation.
