No not always only when the earthquake is off shore if it is on land then there isn't a tsunami. What happens is if the earthquake is off shore it causes a little mountain form and the water that was once in the space that the mountain now takes up creates a wave that gradually picks up more water then more speed and there you have it: A tsunami
What else can I help you with?
Was the earthquake first or tsunami first in Japan 2011?
The earthquake was first and caused the tsunami, like when you throw a stone into a pond first and then the ripples go out.
How soon can a tsunami appear after a tsunami?
There are tsunamis and there are tsunami trains. A tsunami is generated by an underwater earthquake. A new tsunami has to wait for a new earthquake. It is not uncommon for any earthquake to be followed by one or more aftershocks within a matter of hours or days, so a new tsunami can result similarly. Since earthquake behavior is notoriously unpredictable, so is tsunami generation. A single tsunami results in a series of waves with periods ranging from minutes to hours. This is called the tsunami "wave train". There is more information in the related links.
What shows that a tsunami followed the great cascadia earthquake?
There is evidence in the sediment on the U.S. west coast and there are records of a tsunami hitting Japan during that time as well.
When did Japan earthquake happen before or after the tsunami?
The Earthquake occurred before the tsunami as it is what caused the tsunami.
What caused the Japanese earthquake and tsuname?
The earthquake and tsunami in Japan in 2011 were caused by a powerful undersea earthquake that occurred along the subduction zone where the Pacific Plate slides beneath the North American Plate. This movement displaced a vast amount of seawater, generating the destructive tsunami that followed.
What catastrophe followed in japan earthquake?

Does an earthquake always mean an tsunami?
No, Only earthquakes which cause changes to sea floor topography result in tsunami.

Did the people in japan get any warning before the earthquake?
The alarms did sound, but considering how fast the tsunami followed on the heels of the earthquake, there was no time to head for higher ground.
How was the earthquake followed by the tsunami in Japan?
Tsunamis always begin with an earthquake. Sometimes the earthquake is far away from land, and the earthquake itself might not cause catastrophic damage. But the quake happens at sea, and it causes a massive shift in the sea floor. This gets the tsunami going. Tsunamis contain massive amounts of energy and move very rapidly. The recent Japanese quake was close enough to land to cause massive damage, and then the tsunami followed and caused massive damage on its own.
Is a tsunami an earthquake?
No. A tsunami is a giant ocean wave. A tsunami can be caused by an earthquake, but they are completely different things.
