In the Atlantic ocean it's considered a hurricane, in the Pacific it's a typhoon. Tsunami is for certain areas, i.e., Indian Ocean and Pacific Ocean; whereas tidal wave is used—sometimes incorrectly—in other areas.
A tsunami is a seismic sea wave, not a tidal wave. The tsunami is caused by a slipping of the sea bed which is usually triggered by an earthquake. The wave has great depth through the ocean and can travel at 500kph or more. As the sea shallows, the wave gets higher and, depending on the shape of the coast and a few other things can be destructive. Most tsunamis occur in the Pacific Ocean.
Please remember that tides are caused by the gravitational effect that the Moon (and to a lesser extent) the Sun have on the Earth. Tidal waves occur daily and have nothing whatsoever to do with earthquakes.
A tsunami, however, is the result of the displacement of water following a seismic event. Tidal Wave is an old expression with a number of meanings and it is not used seriously by anyone todays.
A tidal bore is a true tidal wave. This is a wave produced when the coastline funnels the incoming tide into a river mouth.
A storm surge is a rising of the sea level in the centre of a Tropical Cyclone caused by the very low pressures. If the storm surge comes ashore on top of the high tide, major flooding can occur.
A cyclone is a low pressure system just as an anti-cyclone is a high pressure system. All low pressure systems are cyclones. A Tropical Cyclone(TC), also known as a Typhoon and a Hurricane, is a tropical revolving storm. All TCs are cyclones but not all cyclones are TCs.

A tsunami is not a title wave, nor is it associated with any weather phenomenon (hurricane, typhoon, etc.), nor is it associated with so called "rough waves". All of these can produce large waves, but because they are produced by different mechanisms, they are not tsunamis.
A tsunami is created by a land shift underwater. The moving land displaces water creating the wave. The most common cause of the movement is an earthquake in subduction zones. However, landslides in the water can also cause tsunamis.
Tsunami is a Japanese word that literally translates to "harbor wave". The height of a tsunami in the open ocean is very small (only a few feet), but when they get close to shore, their height increase as the water depth decreases. Thus, they can appear to originate near a harbor.
I know of no other term for a tsunami that is correct.

It is a geological name , a tsunami is a large ocean wave that is caused by sudden motion on the ocean floor. This sudden motion could be an earthquake, a powerful volcanic eruption, or an underwater landslide.

A lot of people call them title waves.
