into the sea can cause
tsunami’s. Another
reason tsunami’s can
start is by movement of
the Tectonic Plates.

Warnings of tsunamis

tsunami
Moves so fast. Highly sophisticated tsunami-detecting
System was developed by the U.S National Oceanic
Atmospheric Administration. Features deep ocean
Assessment and Reporting of tsunami’s (DART) Sensors.
As a tsunami passes overhead the heart of the system is
bottom-pressure records that are anchored to the ocean
floor. They monitor water pressure and sea level. So
sensitive That they can detect the tiniest changes and
pressure. They Can also sense a rise in sea level of just
half a inch. When Sensing changes, relay the info to large
high-tech buoys that Float above them on the ocean
surface. The buoys have Global positioning system (GPS)
antennas mounted on top Transmit data to satellites which
also send signals to a Regional Warning Center.
