1. Tsunamis can be predicted using seismic sensors and ocean buoys that detect undersea earthquakes and abnormal wave activity, allowing for early warnings.
2. A tsunami is not a single wave but a series of waves, often with the most destructive wave arriving later in the sequence; safety is not guaranteed after the first wave.
3. Grabbing onto a solid object during a tsunami is extremely dangerous because the powerful currents can turn debris into lethal projectiles and sweep objects—and people—away.
4. There are many effective actions to avoid a tsunami, including evacuating immediately to high ground or inland when a warning is issued, following evacuation routes, and staying informed through official alerts.
5. A tsunami is not a tidal wave; it is caused by underwater disturbances like earthquakes or landslides, not by tides, which are driven by gravitational forces from the moon and sun.
6. Being a good swimmer does not help survive a tsunami because the force of the water and debris makes swimming impossible; survival depends on reaching high ground before the waves arrive.
