Why don't towns like to use sirens as a warning signal for tsunamis?

Firstly, sensors in the ocean detect seismic activity. Increases in seismic activity are the main cause of a tsunami and as such, signs of a earthquake at sea can be the beginning of a tsunami.
These initial detectors are supplemented by buoys, round floating plastic objects in the sea, and tide gauges which record an increase in the sea-level. When both of these factors match, it is clear that a tsunami is imminent.

What areas are prone to tsunamis?
tsunamis such as the one that hit Thailand are prone to these areas because these countries lie on plate boundries. Converging and diverging plates cause earthquakes along the plates. When an earthquake happens it's just a normal earthquake (ground shaking..etc) but when an earthquake happens in the ocean it breaks the sea bed(floor) this makes water diverge away from where the earthquake hit. This causes large waves that get higher and faster as they get close to land. Countries in the ring of fire are prone to volcanic eruptions, earthquakes, tsunamis and other natural disasters.

Where did people go in london when the bombs were dropped?
People were warned of a likely air raid by loud sirens, positioned in different parts of towns and cities. During the blitz, they became an almost daily part of life. The sirens made a very loud and long signal or warning sound. For an alert, the siren sound pitch rose and fell alternately. The All Clear was a continuous sound from the siren. Not every alert brought a raid, and sometimes raids happened when no alert had sounded. When people heard the siren they would stop what they were doing and make for a shelter usually located in the back yard or in a basement.
What type of warning systems are in place with tornadoes?
The most advanced tornado warning system belongs to the U.S. Doppler radar scans the wind an rain inside thunderstorms, which allows meteorologists to see if there is rotation in a storm which can produce a tornado. Weather spotters, firefighters, and police can report sightings of rotation in the clouds, funnel clouds, and tornadoes that touch down. If a tornado is spotted or is likely to form soon, then a tornado warning is issued. The warning will be broadcast over TV, radio, the internet, and smartphone apps. In some towns loud sirens will sound if a tornado warning is issued.
