A major earthquake often generate smaller earthquake called?
These smaller earthquakes are called aftershocks. Aftershocks can often be as strong as the earthquake its self and there can be many.
What active fault zone generate earthquakes?
The San Andreas Fault
How is a earthquakes are formed?
Earthquakes don't generate tsunamis - a tsunami is caused by different atmospheric pressure systems coming together. An underwater earthquake would generate a tidal wave, which is caused by the water displaced by the earthquake.
How do geologists measure earthquakes?
The amplitude of the waves created by the earthquake that move thru the earth are measured by a seismometer which creates a seismograph which is produced as a lot of up and down lines. The larger the lines up and down, the more powerful the earthquake. It uses a logarithmic scale called the Richter Scale to measure strength up to 10 ... so a 3 is 10x more powerful than a 2 and so on.
What are the effects earthquakes have on water supply?
Not really. However, in regions that were covered by ice sheets in the last ice age, there have been very small earthquakes that some experts blamed on the Earth's crust there still rising. The Earth's crust floats on the deeper, semi-molten layers. The ice age glaciers added weight to the crust, pushing it deeper. Then the glaciers went away. Even now, the crust is still rebounding from that weight having been removed. As it moves upward, small earthquakes can occur from time to time. Theoretically, if you melted all the remaining glaciers the land beneath them would experience similar effects. In my opinion that's the least of our worries, though.

How does earthquake generated tsunami?
Earthquakes don't generate tsunamis - a tsunami is caused by different atmospheric pressure systems coming together. An underwater earthquake would generate a tidal wave, which is caused by the water displaced by the earthquake.
Is an earthquake a transverse wave or a longitudinal wave?
Earthquakes generate both transverse and longitudinal waves.
How earthquakes generate tsunamis?
The earthquakes that generate tsunamis usually occur at locations known as subduction zones, where one tectonic plate slides under another. The plates will generally snag as they move and build up stress, which is periodically released in the form of earthquakes. Large subduction zone earthquakes cause sections of the sea floor to move up or down, which displaces the water above, triggering tsunamis. Earthquakes can also cause tsunamis indirectly by causing underwater landslides or landslide into water.
Can tsunamis be refered to as seismic waves?
No. Seismic waves are the actual vibrations in the ground generate by an earthquake. Tsunamis are a different matter, nor are all tsunamis triggered by earthquakes.
Are earthquakes caused by wind?
No, earthquakes cannot be caused by the wind at all. Earthquakes are caused by tectonic plate boundaries, where the moving plates generate pressure. The pressure is released as an earthquake. Occasionally earthquakes may be caused by volcanoes, but this is simply another effect of moving tectonic plates. So the wind has no influence whatsoever on earthquakes or seismic activity.
Can earthquakes generate a tsunami?
Yes
Is an earthquake always followed by a tsunami?
No, not all earthquakes are followed by tsunamis. Tsunamis are typically caused by underwater earthquakes or landslides, but not all earthquakes generate tsunamis. The likelihood of a tsunami depends on the magnitude and location of the earthquake.
What happens when earthquakes generate tsunamis?
Japan
How does a Richter magnitude 5 earthquake generate compared to a Richter magnitude 3 earthquake?

Do most earthquakes generate tsunamis?
yes because most earthquakes are under the sea
What active fault zone generate earthquakes?
The San Andreas Fault
