when tectonic plates slide past eachother
The Pacific and North American plates cause most of Alaska's earthquakes.
the movement of tectonic or lithoshereic plates
Undersea earthquakes or volcanic eruptions.
Volcanoes are not the primary cause of earthquakes. Most earthquakes result from the stresses created by tectonic plates moving past or against one another. At transform boundaries there is no mechanism to produce volcanoes, but the movement of the plates will still cause earthquakes. Stresses within a plate can also cause earthquakes.

Of these things, earthquakes are the only ones that can cause tsunamis.
Of course! In fact, underwater earthquakes are a major cause of tsunamis.
most of the time it depends what country it is
Earthquakes are one (but not the only) cause of tsunamis.
Earthquakes have a geological cause.
No, but they are very related. Tectonic plates shift which could cause earthquakes because of the strong vibrations and could also cause the pushing up of magma, causing the volcano to erupt.
