I’ve hit the water so many times, really hard and had hundreds of mild concussions, perhaps even a thousand or more," says surfing legend Garrett McNamara ...

Scientists define a rogue wave as any wave more than twice the height of the waves surrounding it. The Draupner wave, for instance, was 25.6 meters tall, while its neighbors were only 12 meters tall.

Another scale is based on the physical size of the earthquake fault and the amount of slip ... think of it in terms of the energy released by explosives: a magnitude 1 seismic wave releases as much ...

Underwater waves could also be used to reduce the risks of tsunamis and to improve their early warning systems.

Thus, the P wave height becomes larger. The ECG criteria for diagnosing right atrial enlargement (RAE) are as follows: The P wave amplitude in lead II > 2.5 mm, or The upward deflection of the P ...
