Question

what is the units of tsunami?

Answer 1

Tsunami are – technically speaking – ocean waves, but they are quite unlike ordinary ocean

waves at the shoreline. They do not come crashing down upon the shoreline, because they never

become large enough to break. (At most, the front of the wave collapses when it is pushed

forward too fast by the water behind it.) Instead, they are very long-wavelength waves that just

keep going forward when they hit land, surging up the shoreline at 30 mph or more (faster than

you can run). The tsunami picks up people, smashing them into buildings and squishing them

between other objects (e.g., cars) it picks up. So much junk is picked up that people struggle to

stay at the surface to breathe. You may consider water to be soft, but it is quite heavy; just

imagine how much it would hurt to have several jugs of water dropped on top of you. Bodies and

the debris are sucked out into the sea when the water finals slides back into the ocean. Anyone

still alive is typically injured, so they cannot swim for long and drown.

Answer 2

The recorder, sitting at a depth of up to 5,000 meters, measures changes in pressure due to changes in water level. The recorder transmits acoustic signals to the buoy, which, in turn, relays the measurements of wave height to satellites. This information is then used to forecast the progress of a tsunami
